The basic reason photographers use overlays is add texture and elements that weren't in the image as it was shot.
The black square and black area of the gradient on the left have actually lightened a little to become a dark blue, while the white square and white area of the gradient on the right have darkened a little to become a light blue. Color Dodge. Painting with pure black or white produces a distinctly darker or lighter area, but does not result in pure black or white.A Quick and Easy Method for Applying Sky Overlays in Photoshop
Pixels darker than the blend color are replaced, and pixels lighter than the blend color do not change. This experiment helped me to make more sense out of it:.
Patterns or colors overlay the existing pixels while preserving the highlights and shadows of the base color. This basically means in the photography world that there is an extra layer that can be added in the editing or post-production process to add or enhance the look of the photo.

Hard Mix. The Overlay mode seems to have a much stronger effect now with a much more obvious boost in contrast, all because we switched the stacking order of the two layers. Once you have found your overlays, you simply install and use in Photoshop and add texture and effects easily by adjusting the contrast, colors, filters, and resolution to create the perfect look for your image. And now if we look at the image, we can see that simply by adding that Levels adjustment layer and changing its blend mode to Overlay, we've already made a noticeable improvement to the contrast.
Looks at the color information in each channel and subtracts either the blend color from the base color or the base color from the blend color, depending on which has the greater brightness value. What's up with that?
For CMYK images, Hard Mix changes all pixels to the primary subtractive colors cyan, yellow, or magenta , white, or black. Now, Photoshop doesn't actually allow us to move the Background layer, so I'll need to rename it first. Hide the scanlines layer, and this is what you get — a scanlines effect with a vivid image! To fine-tune the contrast, I can simply lower the Opacity of the duplicate adjustment layer.
Let's see what happens when I change the blend mode of the "Gradient and Squares" layer to Overlay:. Vivid Light. The maximum color value is 100. This is useful for adding highlights to an image. That's why the blue color has "won out", so to speak, over the black and white colors we were expecting to see.
Blending with white inverts the base color values; blending with black produces no change. Back in the early days if photographers wanted to add texture to an image, they would create effects such as overexposure, scratching negatives with pins, using sandpaper to affect the negative and even stain the paper before exposing.
Looks at the color information in each channel and divides the blend color from the base color. The base color is the original color in the image.
Looks at the color information in each channel and darkens the base color to reflect the blend color by decreasing the brightness.
