Filter "Lightning Effects" - "Lighting Effects" in Photoshop

The filter allows you to create various lighting effects on the image. You can select this effect by going to the tab filter- "Filter" and opening the list of commands "Render"- Rendering.

Compared to other filters in this group, the filter "Lightning Effects" - "Lighting Effects" is more functional. The filter settings window has a lot of options, thereby allowing you to set a variety of lighting options in the image. On the left side there is a window preview filter results. In it you will see how the selected light source will be applied. By default, it is enclosed in an oval-shaped frame. Two side markers of this frame allow you to change the width of the oval area, and the third - its length. All three markers can be used to rotate the frame. The shape of the frame affects the brightness of the light. So, the wider and shorter the frame, the brighter the light.

In chapter style- "Style" you can choose one of the seventeen lighting styles provided. Some of the styles on this list have more than one light source. It should be noted that each light source is displayed in the center of the viewport as a small white circle, and the frame shape is editable for any light source.

In addition to the lighting style, you can choose the type of light source. To do this, open the drop-down list in the group "light type"- "Source".

Parameter Directional- "Daylight" allows you to set diffused light from a source that is far away.

When applying the parameter "Omni"- "Bulb" light source is located within the image, and the light spreads evenly in all directions. When choosing of this type The lighting frame is displayed as a circle.

Parameter "Spotlight"- Spotlight is the default lighting type. This mode creates an elliptical light spot on the image surface.

You can set the intensity of illumination using the parameter "Intensity"- "Intensity", and the focusing of the light is set by changing the parameter "Focus"- "Focus".

Section Options "Properties"- "Properties" are used to change additional lighting properties. Slider "gloss"- "Gloss" allows you to change the surface that reflects light. Here you can simulate a reflection, both on matte and glossy paper.

Parameter changes "Material"- "Material" allows you to varying degrees to simulate the material on which the light falls. Meaning plastic- "Plastic" indicates that the color of the incident light must be present in the reflected light, and the value Metallic- "Metal" says that the color of the object should be represented in reflected light.

Light exposure is adjusted by changing the parameter Exposure- "Exposure" while using the slider Ambiance- "Environment" you can change the overall brightness of the image.

In the next tutorial, we'll take a closer look at how to create different lighting effects using the options in the filter settings dialog.

Shadows are a very important aspect in any collage. The same goes for lighting effects, if the shadows are applied correctly, then your image can end up being stunning. In this tutorial, I'll show you several ways to create realistic shadows in Photoshop.
In the first step there will be only theory to help you understand how lights and shadows work, and in the next steps I will show you how to create shadows.

Light source and shadow angles.
Before you start doing anything with your image, you must decide whether you need shadows or not. For orientation, you first need to determine the main light source.

As you can see, in the original image, the light source is located at the top left. In the collage, the sky and clouds are also illuminated from the top left. You must always respect the direction of the light. It is necessary to determine the elements in the image that will serve as a guide for you to create light and shadow.
Below is a similar case. But this time the light source is on the right side and again the artist used the highlights on the body of the model as a guide when creating (a) the collage.

It also happens that we can not find a landmark that will help us determine the position of the main light source, but existing shadows in the image can help you. Here is an example.

No original image road sign, I added it to Photoshop. Assuming I didn't have a starting point to help me decide where the main light source (in this case, the sun) is, I created the road sign's shadow based on the shadows from the man and the girl. I created it at the same angle and with the same opacity. If the original shadow you are using as a guide is blurry, you can apply to the shadow Gaussian blur(Gaussian Blur) to make it as close to the original shadow as possible.

This is a simple theory. Simply put, you must determine the light source in order to know how to create shadows. In the following steps, I'll show you how to create real shadows from scratch. I will show mine own methodology, but you can customize it to your liking. There are different types of shadows, so to make it easier for me to explain and for you to understand, I will give them different names.

Contiguous Shadow
I'll call this type of shadow "contact shadow" because I don't know its real name. This is very important view shadows, because it actually tells you if the object is on or close to the surface. The image below shows an example of a real shadow, where you can clearly see what type of shadow it is.

Recreating this type of shadow in Photoshop is not challenging task but takes some practice. For example, I took an image that I used for my other tutorial. I separated the model from her old background and placed her on a new one to create a collage. As you can see, it looks a little dull, obviously lacking shadows, and the model looks like it's hanging in the air.

The way I create the shadows you see in the image below is this: I take Brush(Brush) medium size (depends on the size of the collage), set it Pressure(Flow) around 30%, and Opacity(Opacity) brush - around 25%. Then I start painting the edges of the object where it touches the surface. I paint over the edges, so to speak, from the inside. Look at the image below for a better idea.

This is what I call a "before and after" touching shadow. I do not know its formal name.

soft shadow
This type of shadow is perhaps even more important than the touch shadow, because it is more visible and if you create it correctly, you may not need the touch shadow we talked about above.
In this case, you can be a little looser, since there is no need to be too precise here. Just take a soft brush, set the value Rigidity(Hardness) in the region of 20-45% and paint over the areas around the object you are working with. Keep in mind that the further you move away from the object, the less opaque the shadow will be as it fades.

Look at the image below. I painted the shadows with a large soft brush at a low value. Opacity(Opacity) (20% or so). As you can see, it's impossible to clearly define the figure of the girl in the shadow as it's too blurry, but it definitely adds realism to the overall scene. Also notice how the shadow loses intensity as it gets further away from the subject. It was all created with a mouse, not a tablet.

Cast shadow
If you want to create more realistic shadows in Photoshop then you need to use a different technique. Almost always in Photoshop, there are multiple ways to achieve the same result. Simply put, this technique is about using the shape of an object to create a shadow.

Method 1
One way to do this is to duplicate the layer, then scale it down. Brightness(Lightness) to 0. Then, place the duplicated layer under the original layer and rename it Shadow (Shadow) if you want.
I have already made a small demo video on how to create shadows of this kind. You can watch it. After that, use the tool Distortion(Distort) to adjust the shadow to your liking. You can apply Gaussian blur(Gaussian Blur) if you want to blur the shadow, and you can also adjust Opacity(Opacity) layer.

Then I applied some Gaussian blur(Gaussian Blur), reduced Opacity(Opacity) layer and used Layer mask(Layer Mask) and Gradient(Gradient) to make the shadow fade. Then, using distortion(Distort) (Ctrl+T or menu Editing(edit)- Transformation(Transform)- Distortion(Distort)) I tilted it a bit.

Method 2
The second way to achieve the same result as in the image above is to use layer style(Layer Styles). I believe it is lighter and faster. I'll show you a really cool way that a lot of people don't know.

Just open a window layer style(Layer Styles) (in my example the Tower layer) and add Shadow(Drop Shadow). The most important setting here is Size(Size) shadows. With this setting you control the degree of blurring of your shadow.
Zoom in Opacity(Opacity) to 100%, because then you can reduce it as desired using the slider Opacity(Opacity) in the layers palette. I used a high value Offsets(Distance) in this example, so that you can see the shadow being created better, but this parameter is not important.

Now the most interesting. You can turn this shadow into a separate layer. Right click on the shadow effect name for the layer in the layers palette and select Create layer(Create layer).

This action creates new layer with the same settings Blend mode(Blend Mode) and Opacity(Opacity). You can do this with any effect. Then, Reflect(Flip) the layer and scale it down if necessary Opacity(Opacity). Repeat the steps for tilting the shadow above.

I think what I have said about shadows is enough. Let's now move on to lighting. I'll show you some of the ways I use to create realistic light.

incident light
I want to show you how I created the lighting effects shown in the image below. I use this method in my collage, which I am currently working on. I will write whole lesson by him.

Creating this kind of lighting effect in Photoshop is not difficult, but if you want realistic incident light, then you have to think a little. Blending modes are very important here. Don't be afraid to create each light effect on a separate layer and apply a different blending mode for each of them.
The first thing I created is the light source. I took a fairly large soft yellow brush and painted a big dot. Then I went through all the blending modes to see which one works best for me.
Keep in mind that blend modes affect brightness values. If the light doesn't look the way you want with any of the blend modes, try using a darker, less saturated color. In this example, I've used dark yellow to create the glow.

I then created the final glow using a filter glare(Lens Flare) in the menu Filter(Filter)- rendering(Rendering)- glare(Lens Flare). I created a square selection, filled it with black on a new layer and added a highlight in the center of this black square. Then changed its color to yellow with Adjustment layer(Adjustment Layer) Color tone/ Saturation(Hue/ Saturation) and changed the layer blend mode to Screen/Lightening(Screen) to hide the black areas of the square.

When the light source is ready, it is necessary to reproduce the light falling from it on other objects, such as the ground or walls. The most common way to do this is to use a soft brush and, in this case, yellow.
I found that the blend modes Lightening Basics(color dodge), Bright light(Vivid Light) and Linear Dodge(Add) (Linear Dodge (Add)) are best for creating lighting effects, but as I said, it depends on the colors and brightness levels of your background. The realism of the lighting depends on where you place it.

As you can see in the image above, the addition of light on the ground makes the collage even more realistic. It was made with a large soft yellow brush and blending mode Lightening Basics(Color Dodge) then I used the tool Distortion(Distort) (Ctrl+T) and squeezed it horizontally. Thanks to the addition of lighting on the wall on the left, it became even more realistic. Therefore, as I said above, it all depends on where you place the lighting. To create the lighting on the wall, I simply duplicated the ground lighting and reflected it.

Surface lighting
Another way to create different kind lighting - use layer style(Layer Styles). This technique is used when the subject is illuminated from the side or from behind.
This technique consists of adding Inner glow(Inner Shadow) and use the blending mode that is more suitable in a given situation.
Using the same blend mode doesn't always work, you'll have to tweak it. Our goal is to recreate the light at the edges of the object.

The color of the lighting depends on whether you are working on a collage with daylight or a night scene. If you are using modes Lightening(Dodge) or Bright light(Vivid Light), then you should use dark colors as these blending modes will make them brighter. You will have to try and fail many times before you find the right brightness value. It is also not necessary that the effect be very noticeable. Even a subtle effect will change the look of your object.
I sketched an illustration of what I just explained. This is a rough option, but it suits us. Look at the image below. I applied to him inner shadow(Inner Shadow) with the settings shown in the image above.

Here's another VinternnV collage from deviantART.

This method has its drawbacks. When we apply settings Inner shadow(Inner Shadow), it often creates a lighting effect on unwanted areas.
I usually increase the value of the parameter Bias(Distance) and change Corner(Angle) to adjust to the direction of the light source, but even then you may get unwanted results. Increasing the settings Size(Size), you get a more blurry effect, but usually just a thin line of light is enough to make it look good. Look at the image below for clarity. I made the effect very strong so you can see it better.

As you can see in the image above, the result of applying Inner glow(Inner Shadow) to create lighting became some unwanted effects. They don't look terrible in this example, but let's say I don't want the area I circled in the image above to have this kind of lighting effect.
How to get rid of this without affecting the areas that we have in order? You cannot use the eraser because it Layer Style(Layer Style). There was a time when I had great difficulties with this, but in the end I found a solution to this problem.

The solution is to transform the style (in this case inner shadow(Inner Shadow) on a separate layer, as I said earlier when we talked about shadows). I bet not many people use this trick in Photoshop, but it's really useful when you want to use an effect that's already been used, for example. For example, if you want to use two different shadow effects.

So, to expand the possibilities of layer effects, right-click on the desired effect and select Create layer(Create layer). With this action, you automatically create a new clipping mask(clipping mask) layer with Opacity(Opacity) and blending mode that you have stopped for this layer style. After that, you can create a layer mask and mask out the unwanted areas.

global illumination
The last kind of lighting effect is the global illumination which I create with a filter lighting effect(Lighting effect). I use this filter in almost all my collages in the final steps. This effect will make your collage 99% better. This is a destructive filter, in other words, as soon as you apply it, it will immediately change your image, and this effect cannot be undone. You can find this light filter in the menu Filter(Filter)- rendering(Render)- lighting effects(Lighting Effects).

But there is a non-destructive way to apply this filter if you convert the layer to smart object(Smart Object). You can convert a regular layer to smart object(Smart Object) in the layers palette. Right click on the layer and select Convert to Smart Object(Smart object). Below you can see some examples of the global illumination effect.

That's it for shadows and lighting. I hope you have cleared up something for yourself. This is all for your experiments and your practice.

• To add a glow effect in Photoshop, first of all, it is necessary that the object whose outlines will glow be on a separate layer. How to separate an object from the background has been written many times in other articles, we will not dwell on this now in our instructions.

Instruction

So, we have a separate layer with an object. To make it more convenient to adjust the glow parameters, it is advisable to put another layer of a dark color under it, against which all the nuances will be.

Select the layer with the object. Go to menu Layer>Layer Style>Outer Glow (Glow outward), or click on the "effect fx" on the layers panel.

We see in front of a fairly extensive field for settings:

– glow color; it can be solid or change its color, depending on the distance to the object.

– halo width and glow intensity

– you can also vary the glow overlay algorithm – Lighten and Screen modes are best suited
Thus, we adjust the glow of the outline of the object to the outside. After that, go to the next tab Inner Glow (Glow inside). The settings here are similar.
To make the picture look natural, you need to remember that even if, according to the logic of things, the object glows only outward, then any optical system, including the human eye, due to the non-absolute transparency of the cornea and lens, it slightly blurs bright highlights, they look beyond the boundaries of the light source, so with an intense glow outside the Outer Glow contour, you still need to play along with a slight Inner Glow glow inside it.

In our composition, there can be any number of layers with objects, each of which can have individual parameters - the color of the glow and its character.
In addition, if we want to depict a single point light source, we can use the Lens Flare filter (in the Filer>Render>Lens Flare menu), which simulates the reaction of various photographic lenses to the appearance of a bright light source in the frame. Thus, we can add any number of glowing light bulbs, lamps and spotlights to the composition.

By varying and combining glow effects, applying them to different layers, we can achieve very bright and memorable - fantastic and realistic results.

Create a new document 500x500 pixels, and then select the gradient fill from the toolbar. Set a radial gradient and choose a suitable transition (for example, a transition from black to red). Stretch the gradient on the created image, and then duplicate the layer (Duplicate layer) and change the blending mode to Color Dodge.

Now create a new layer and in the filter section (Filter) select the Render> Clouds option with the original palette options - black and white. Set the layer opacity to 30%, then open the Sketch filters section and select the Chrome filter. Set the filter values ​​to 4 and 7, and then set the transparency back to 100%. Set the layer blending mode to Hard Mix.

Use the Pen Tool to create glowing lines. Draw an arbitrary smooth line with this tool, bending it along own will and editing the bend with anchor points. Create a new layer and select a 3 px brush desired color, switch back to the Pen Tool.

Light plays a key role in photography. This is the main tool, the quality of the resulting images largely depends on the skillful use of it. Light has different characteristics(brightness / color temperature and others) that affect the final photo image. Even experienced photographers often have dimly lit areas in their pictures, which can be the result of improper exposure, backlighting, or flash use. Sometimes these kinds of brightness/lighting differences in a photo are part of the creative intent. However, in most cases, the appearance of deep shadows or highly lit areas in the photo is an accident caused by certain errors. And in such a situation, the photographer has to eliminate brightness defects.

Actually, unpleasant lighting differences in the photograph are expressed in the gradient of the transition between the light and shadow areas. That is, the illuminated part of the object can suddenly break off abruptly and turn into a shadow. High-quality photographic images are characterized by a smoother transition from light areas to shadows. The photo must be aligned in terms of brightness. As a rule, areas with deep shadows appear in a photograph when using hard light.

It is hard light that creates deep drop shadows with pronounced borders in the picture. Sometimes such shadows are part of the artistic intent of the photographer, for example, when shooting male portraits to make your photos more contrasty and dramatic. But in most cases, they just spoil the picture. Soft light, on the contrary, is highly recommended for shooting the same portraits, since there are no lighting differences in the photographic image and the transition from light to shadow is smooth. This photo looks much more attractive.

The quality of light is affected by the distance from the light source to the object being photographed, as well as the size of the source relative to the size of the object. For example, on a bright sunny day, unpleasant deep shadows form in a photograph because the sun is very far from the subject being photographed. The dynamic range of the sensor of modern cameras is still not wide enough to correctly display a significant spread in brightness levels. As a result, the frames are underexposed. In the same case, if the light passes through the clouds in the sky, it will scatter, creating a pleasant, soft lighting. Moreover, in this situation, clouds located much closer to the subject than the sun can be considered as a light source in this situation. After all, it is clouds that scatter light.

In addition to underexposed shots, you can often encounter a situation where overexposed areas appear on the photo image, which completely spoil the picture. This is due to errors in exposure or incorrect lighting when shooting in indoors. Overexposed areas and images are much more difficult to deal with in post-processing, and sometimes it becomes almost impossible to seriously improve a photo. So you need to be careful and responsibly approach the choice of exposure parameters and other settings.

In practice, to get good results, you should always strive to use soft, diffused light. To achieve softening of light, you can use various reflectors and diffusers. As a diffuser, any translucent object that is placed between the light source and the object being photographed is suitable. It can be both professional softboxes and a regular sheet or translucent fabric.

Too hard light can be softened by reflecting it. For this, special reflectors are used, on which light rays from a light source should fall. The reflector is positioned in such a way that the reflected rays hit the subject. When shooting indoors, you can simply aim an external flash at the ceiling or walls to bounce the light. It is only necessary to take into account that when the light is scattered or reflected, the illumination of the object decreases, therefore, competent corrections should be made to the shooting parameters.

But how to remove shadows or even out brightness differences in a photo if the shooting has already been completed? Of course, for this you will have to use the capabilities of various graphic editors and special software. Especially the need to eliminate lighting differences or equalize brightness arises when such defects already become clearly visible. To work with the brightness of the photo, you can use the popular editor Adobe Photoshop. It's worth a try first automatic modes photo corrections, which are located in the menu Images - Corrections.

In particular, you will have access to such commands as Color Correction, Auto Contrast and Tone Correction. The simple Auto Contrast function, for example, converts the lightest pixels in an image to white and the darkest pixels to black, and thus more accurately distributes gray levels between them. This can have a positive effect on the brightness and contrast of the image. However, the results of using automatic functions may not be the best, but thanks to them you will be able to understand which path to take next.

To equalize the brightness of a layer in the Photoshop editor, you can use the Equalize command in the same menu. This feature will help improve a photo that lacks contrast or is too dark. For a smooth change in brightness / contrast, use the menu Image - Correction - Brightness / Contrast. You can lighten the layer a bit by moving the slider to the right. If, on the contrary, it is necessary to darken the image, then move the slider to the left. In the same simple way, you can adjust the contrast of the image.

If you need to quickly increase the brightness of the image, leveling out the differences in lighting, you can apply the Blur filter. To do this, you must first create a duplicate layer, then select the menu Filter - Blur - Gaussian Blur. We choose the optimal value in the region of 9.0. Next, use the Overlay function for this layer. We experimentally select the value of the transparency of the layer and, in the end, we get a brighter and beautiful photo. You can also use the Healing Brush tool to create a smoother transition between light and dark areas of an image.

One of the most common problems that photographers face when post-processing images is the need to eliminate deep shadows that contrast sharply with the highlights of the photo. There are quite a few ways to remove ugly deep shadows.

Example 1 (Using Photoshop)

There is an image:

We see that it has a strongly illuminated top and a dark bottom.

Open the image in Photoshop, go to Image-Adjustments-Shadow/Highlight and start moving the sliders.

As a result, we get a version of the original image with an improved balance of light and shadow.

In addition to Photoshop, many other programs provide similar capabilities. For example, the convenient and free photo viewer FastStone Image Viewer has editing functions that make it easy to fix some flaws in a photo.

Example 2 (Using FastStone Image Viewer)

There is an image:

We are interested in the black area between the stones.

Open the image in FastStone Image Viewer, select "Lightness Correction" on the left panel. A panel with sliders opens at the bottom, we are interested in two sliders in a green frame.

Having experimented a little with the parameters of light and shadow, we find that in the black area there is a pigeon's nest, in which he was at the moment of photographing.

There are also special programs to even out the brightness of uneven lighting in photographs. These include, in particular, the program BrightnessGuide, which helps to quickly lighten the dark areas of the picture, leaving the light untouched. It can be a good help for those photographers who often have to shoot in low or uneven lighting conditions.
