Oh Cass that is quite a problem ... just make sure not to use anything you find in your computer that says "My Documents - Already submitted to RetouchPRO" or something like that ... Hope that helps ?
Sorry had to say it , your remark was very funny

[Frank Lopes]

No self-plagiarism????

Does that mean that I can't say what I've already said? :-)

Precisely

Actually, it just means don't paste in something you've already published somewhere else. The goal is original tutorials, not to collect previously-published tutorials.

Tangent:
It occurs to me that is someone were to volunteer to reply here posting the URLs of tutorials submitted within the contest period and edit it occasionally to update the list, that would be a very good thing

Hi everyone.

Here is my entry.
http://retouchpro.com/tutorials/index.php?m=show&id=255

This took ages. I hope it’s useful. I would be most grateful if you would check my method / numbers / logic / English etc.

Some of the screen shots were difficult to capture. Holding down the left mouse button and the Alt key AND trying to get a screen shot.

I have just tried to add my pictures. It says ‘Uploaded Successfully’ but the picture is not there.? I am using Firefox. Should I try IE?

Ken.

[Frank Lopes]

I had the same problem with Firefox... When I switched to IE it worked fine...

Hi Frank.

I tried IE. But when I click the ‘Insert Picture’ button I get a bleep but the Picture dialog box does not open. I think it may be something to do with popups blocked.

Ken.

EDIT.

I sorted it. Firefox would Not upload the images. I got IE to upload them after I switched off the popup blocker.

Thanks.

Hey that was a great tutorial and thanks for posting it, Flora. I'm going to use that all the time. Just wondering...When you use Apply Image + Difference blending mode what represents the blend color and what represents the base color.

From Photoshop Help files

"Difference 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. Blending with white inverts the base color values; blending with black produces no change."

Thanks Phil!!

... If I have understood correctly the Photoshop help file on this ... (but not sure about it.. ) ... I would say that the base colour is represented by the 'colours' of the blue Channel wich I used as source ... and the pure white mask represent the blend colour .... but it could be exactly the opposite!!!

[BobJones]

It's the other way around.

If you think of how the blending modes work on layers, the blending layer is the one on top and the base layer is the one below. Applying images is similar, the blending color is from the image you are applying and the base color is from the one you are applying it to.

In this example, you are applying the blue channel (blend) to the white mask channel (base). In difference mode, blending with white inverts so, in effect, what you have done is to simply load the levels adjustment layer mask with an inverted copy of the blue channel.
