I'd like in on this please, Colette.

I have absolutely no idea what any of this means. ROFL I need a step by step, blow by blow. All that technical talk about pixels and I'm like "HUH?" I have CS2 and haven't downloaded CS3 although I have it, so I can use either.

Somebody want to give me a tutorial as to exactly what is expected?

That's the idea, to learn what to expect when using different blending modes. Would you like to join in?

Oh I use them all the time when layering. So it's layering but concentrating and explaining which mode we use, right?

I was trying to make it too complicated. OH and for those who want some explanation:

Blending Modes

COUNT ME IN.

Jutilda, you're in and thanks for the link to additional explanations.

I've posted the week one definitions in the original post. -- Difference and Exclusion

Week one starts on Saturday so you've got lots of time to try and find images you think will work well with these based on the definitions.

Just bumping in case anyone else wants to join us. Read the original post for week 1 activities.

I'd like to try this too, I have no understanding at all about blending modes, so maybe this'll help. :)

Just re-iterating what will happen in March with blending modes.

... and bumping the thread, of course ;o)

We've had a couple of months to do overlays in general, why not do a month where we concentrate on a set of blending modes per week.

Blending Modes

Since I use PS CS2 I would use the divisions in that program.

I think it would be a chance to really get to know the blending modes and what type of images they work best on.

Anyone interested?

So far, those interested are:

WEEK ONE

DIFFERENCE: As the name infers, this mode looks at the differences between pixels of the top and bottom layers. Large differences will lighten, small differences will darken. ( From the November 2007 issue of Photography Monthly)

A more thorough definition can be found in a number of books. The following is from Adobe Photoshop CS2 for Photographers.

Subtracts the base colour from the blending colour or vice versa depending on whichever has the highest brightness value. If one of the colours is black (value 0) then the brighter colour will appear in the blended image. The colour of the blended image depends on the brightness value of the blended image.

Though strange and wonderful results can be achieved with this blending mode (see cow images in my portfolio), a practical use is for determining alignment of images of the same scene. Using difference mode on two layers with the same image will produce a completely black image. However, areas that are out of alignment will show some colour.

EXCLUSION: More subtle version of difference. Lighter the pixels in the top layer the stronger the effect.

If the top image is pure white then the effect of exclusion will be to completely invert the base image.
