2291.Originally, this was Missive 1816, done on the 18th of October 2006. I figured that since layer blending modes was one of the thumping hearts of how to use Photoshop, it would be good to reasearch and make notes on just what each blending mod did and make my findings public here.
Photoshop blending modes allow you to, of course, take two layers and make one influence the other in some way. Knowing how they work makes using them a thing of knowledge rather than of chance. The problem with blending modes is there's so darned many of them!, and some of the names are far from suggestive about what they do. You have all these great tools, but more than you can use, and you're not certain that the one you use will be the one you need.
That's not to say trial'n'error is inferior, but there's a time when you have the time to muck around, and there's a time when you don't (say it with me: dead-line. Very good.). Therefore, this exploration.
At the time, I planned on going through each group, then after I did this first group, I got distracted by … well, who knows? But I'm funking around with the Shop again, which means that it may be timely to go back into the blending modes again, with gun and camera.
That said, on with the show …
Working the last few tutorials has again reminded me how useful Photoshop's blending modes are. However, when I was trained in PS, I wasn't given a very deep understanding of them. The modes were used in a trial-and-error fashion, which, for a beginner, was kind of a relief ... the list can be eye-glazing to the tyro.
However, for long-term artistic development, one really wants to have a somewhat deeper understanding of what blending modes (with their odd names) mean. Along the way, and from various sources, I've made my own list. It's a work in progress, but it helps me a bit.
Knowing which tool to use improves your workflow; you save yourself the trial-and-error step and go straight to tweaking the mode.
The blending modes in PS are divided into a handful of groups, which are related by the general effect they have on the pixels they govern. In the following, I use three terms: base color is the original color in the image, blend color is the color that's being applied with the editing tool, and result color is the color that, of course, results.
Herewith the list, divided by groups:
The Normal Group: causes no fundamental change to the pixel's color values
The Lighten Group: Blends the pixels on the active layer to a lighter color depending on the setting.

In the following, I use three terms: base color is the original color in the image, blend color is the color that's being applied with the editing tool, and result color is the color that, of course, results.
Herewith the list, divided by groups:
The Normal Group: causes no fundamental change to the pixel's color values
- Normal Normal blending is just what it says; the normal mode of operation. To be specific, any painted pixel on a layer above simply covers up any pixel below it. This is the default.
- Dissolve This one I don't use much. On a layer with a faded edge, Dissolve randomly replaces the pixel color with the blend color, depending on the opacity of the location. On something with a soft, blurry fade, Dissolving with another layer will turn it into a choppy, noise-y sort of thing. If you drop layer opacity below 100%, Dissolve will dither all pixels.
- Darken The result of this is the blend color or the base color, whichever is the darker one. If the pixel is lighter than the blend color it's replaced; if not, no change.
- Multiply Mathematically multiplies the two colors together; the result is the new blend. Multiplying any color by black will give you black; multiplication with white produces no change. Paint with this mode active and get darker and darker colors with each successive stroke.
- Color Burn darkens the base color to reflect the blend color by increasing the contrast. I'm not too clear on what that verbiage means, but the result is what one site calls "crisp, toasty" colors. They look rich, warm, and overexposed.
- Linear Burn darkens the base color to reflecting the blend color by increasing the brightness. The result is less lurid and smoother than Color Burn.
The Lighten Group: Blends the pixels on the active layer to a lighter color depending on the setting.
- Lighten replaces the base color with either the base color or the blend color depending; pixels darker than the blend color are replaced, and pixels lighter are not.
- Screen mathematically inverts the colors, multiplies them, then inverts them again. The result is usually a lighter image. The name is wholly non-intuitive.
- Color Dodge with the dodge modes we once again return to the darkroom. Dodging an image was the opposite of burning an image; instead of isolating an image for more light, the photographer used a paddle-shaped tool with a wire handle to block out the light, resulting in a lighter area. Similar to Color Burn, Color Dodge lightens the base to reflect the blend by decreasing the contrast. Each color becomes a value-brightness multiplier; black drops out entirely.
- Linear Dodge Lightens the base color to reflect the blend by decreasing the brightness. Gives a smoother effect than Color Dodging.

Do you know any good intarwebintz resources for PSP? I've used it forever but always felt like i was just scratching it. I don't have the brand new one, using 7 I think right now.
that's a very good question, Pril. Since you made this inquiry, I've been surfing around trying to find some.
An acceptable place to start is psdututs.com. Last I played around over there, they have tutorials for all sorts of levels of PS.
The problem is that Photoshoppers tend to love the new and shiny, so you find a lot of CS, CS2, CS3, CS4. A lot of Photoshop, though, the most-used tools, haven't deviated too far from the basics which have existed since PS7, so go into what you find with a little care and you'll find out that your needs may be covered by what's already out there.
There really isn't a good site out there for your basic Photoshop skillz, and that's a shame, because a lot of people want to us PS, have things like PS7 on thier machines, but don't know the first thing about it.
But basic PS skills are pretty universal between the versions, is what I've found.
Maybe someone should come up with a site of just basic how-to-use-PS basics. Heck, maybe I will. I don't see anyone else doing it.
