Hi there everyone,

Quite a while ago, I used a tutorial on GUG for fading an image to transparency, which I wanted to use as the top of a web page background. For clarification, you can look here at the image:

I'm trying to do the same thing now, but with grass to green. The problem I'm having is that I can't remember how I did it and GUG went the way of the spam farm :)

I remember it was two layers, one with transforming black to transparent at the midline, using gaussian(I think) blur to soften the line of transormation and then overlaying, but I can't remember the details enough to reproduce it.

Does someone know of an alternate location for the tutorial that I need or maybe more detailed instructions leading to the same end?

Those are basically two layers: On the bottom layer there's the blue (in your case,
green) gradient, the snowflakes are on a transparent second layer. To achieve the
transitional effect, apply a black-to-white gradient as a layer mask to the snowflakes
layer ('Layers > Add Layer Mask', with the default setting; then apply the black-to-white
gradient to this layer, and as a third step, 'Apply Layer Mask'. Finally, merge the two
layers with 'Flatten Image' or CTRL+M (Merge Visible Layers). That's basically it.

HTH,

Claus

I have been stuggling with this task for a while myself. When you clever ones nut it out, please publish a "Fade an Image to transparent" and "fade an image to white" tutorial "for complete idiots" (aka me) Thanks!
