Blending modes and photomanipulations
Few words about most used blending modes (bm), how they affect the image (positive and negative moments).
First of all I want to remind about the option of creating layer filled with neutral colour for chosen blending mode. Holding Alt press icon "create a new layer", Photoshop will show you window like this:
Just select desired bm and check "fill with ... neutral color". Sometimes it's very helpful.
Second, when you use blending modes for toning for example, use option "new adjustment layer - solid colour" instead of filling new layer with bucket. Solid color doesn't increase size of your psd file as much as pixel layer does.
And third - brush, clone stamp, history brush, bucket/gradient, all these tools have option to select bm in their settings. That means you can mix effect of several b-modes choosing different ones for the layer and for the tool you're using.
Now some info about several most used b-modes:
What you have to know about it - it's reducing contrast of the area where it's applied. That's why it's used for drawing shadows, turning day into night etc. So be careful, for eg - you decided to darken the image that doesn't have much contrast - it will look totally flat
In case you're really need to use that image, do some dodge and burn before.
Important! Do not use multiply to draw shadows on glittery objects like gems, glass etc. Use color burn
instead. Highlights should be saved!
Foggy landscapes, contour lighting, lens flares - screen is great for that. Also reducing contrast, be careful using with low contrast images. Black is neutral colour for screen, if you have some nice texture on black bg, set it to screen, bg will disappear
3. Soft light/Overlay
Important! Overlay is not
boosted soft light, their effects differ, even if it's sometimes not obvious. Who's interested why - read this zhur74.livejournal.com/14839.h…
(warning - very technical info, and it's in Russian, but you don't need to know Russian to compare curves)
Photomanipulators like to use these two for different glowing effects, what you have to know - both blending modes have almost no effect on very dark or very light areas. They work very smooth, that makes them perfect for setting lighting nuances of the scene, for eg I worked on one of my pieces using overlay (red for lighting areas, purple for darken)
Copies hue and saturation of the chosen color to your image, luminosity remains the same. Do not use it for complete recolouring of the object, objects are multicoloured! It's equal to using hue/saturation with "colourize" option checked, but without ability to change lightness.
Can be helpful when you want to get rid of unwanted colours, you may just paint on new layer picking samples from "good" areas, or make a copy of the layer, set it to colour and using smudge tool or mixer brush or clone stamp copy colour from close areas.
Hope this journal will somehow be useful!
