GIMP is just simply amazing entirely. =)

I took a 500x500 blank image and rendered the checkerboard pattern (Filters>Render>Patern>Checkerboard).
I rescaled the image 200% (Layer>Scale Layer> 200%) and duplicated the layer twice.
I used the shear tool (I love the new icons) to shear on layer 100 left, another 100 right and
did layer to image size on all layers. I set the image mode to greyscale and composed them.
I did some color levels afterward. I later added some text and some white haze.

This is what I got.

Ah! Another way to move stuff. That image is just plain fun, Greg. Very creative!

I firmly believe that all things are possible with Gimp!

This is a cool effect. Has anyone tried animating the different images? Wonder what that would look like?

Now this is a truly sweet idea!!

Thanks, O, for holding my hand, lol. I managed to do it, all I had to figure out was which image to recompose, but it was obvious since only the right one would allow it, lol.

woo, yay, I can do it!!! Not a very good example, lol. Obviously I need baby steps.

OH yeah, next up is a flower. I iwarped the right side and tried to keep the left side normal. So, next time I can play, I will go back and try the original tut to see if I can do it right!

Check the title bar of the images. The one that says grayscale is the one.

Looks like you're on your way, Toni!! WTG!

hmmm, I can do an image by decomposing and working on the different layers, recomposing. But if I try to use 3 different images, decompose each image, take one layer from each and put in original for the layers, I can't seem to figure out how to recompose anything...the choice is greyed out in everything.

You only want the layers from the three different images, one red, one green and one blue. No original images in the layers.

The 3 decomposed color layers will then compose for you.

Also I think yo may have to make sure that each layer has no alpha channel. If they have an alpha channel, the compose routine can't handle it.

I only take one of the decomposed layers (yeas, diff color from each one) and move them to the original stack, so I end up with just one red layer, one blue layer, one green layer...and the original background which I make invisible...but I did not know to check for alpha channel. Anyway, next time, lol. For now, I took a poster off of the internet and "harris-ed" it, and then took the big title section and edge detected it, got rid of all but the edge lines, and stuck it on top to make it a bit snappier. Well, it's not exactly better, in fact it looks less sharp, but it's interesting with the Harris effect.
original:edited:

None of the color layers (r, g & b) are flattened (they have alpha channels) when I decompose an image. They are grayscale though.

When I compose them the final image is flattened.

I have to think about this then, because I have seen the problem that 2-ton describes and I thought I fixed it with the alpha channel. I'm going to play with it.

Perhaps you were thinking about the Compose dialog screen. In that the alpha channel is grayed out.

Procedure 'gimp-drawable-bpp' has been called with an invalid ID for argument 'drawable'. Most likely a plug-in is trying to work on a layer that doesn't exist any longer.

this is the message I get when I try to recompose ...
it all works fine, though, when I just take one pic and decompose, modify layers, recompose.

Recomposing does not like layers with offsets. Layer offsets are the result of moving the layers.

Anyway, right-click every layer and select layer to image size. That way there are no offset layers. See if that gets rid of that error message.

I don't use Re-compose, I use Compose. Compose makes a separate image.

I was pretty sure I did a all layers to image size after I did the offsetting. I am not sure how to use compose...I'll have to give that a shot.

Compose is in the same place as Recompose.

Colors > Components > Compose

When I did the alpha channel trick, I also did a layer to image size, on each layer. That may be what fixed the image.

I was so impressed with Oregonians candle, I tried it with one of my candle pix. This is just so much fun!
