Seashore help

[shayneisspiffy]

Hi there, I'm a new mac user but have steadily began to get the hang of it.
I recently downloaded the image editing software of Seashore.
Currently I am trying to make a photo black and white apart from a certain part of it that I want to remain the original colour e.g. a black and white photo of someone but their lips remain pink.
I have tried fiddling around with the different layers and erasing part of one layer (black and white) to let the other one come through (the colour layer) but have so far been unsuccessful. I have been to the seashore website but have find it very unhelpful. I have come to this forum many times and have always either found the answer I needed or, at the very least, been pointed in the right direction, so fingers crossed someone out there can help me.
Thank you.
Shayne.

I have never used seashore, however I did use photoshop.

If I were you I would cut out the part you want in colour. Delete the rest. Copy it to a new layer. Make the original layer black and white. Now in the layer window you must place the "colour" layer above the "original black/white" layer.

This works with photoshop, and looking at the screenshots, it should work with seashore too.

Thanks

Thank you for your suggestion, I've tried to do that, but by erasing parts of the photo it just turns the layer white where I've erased, ideally I would want it to turn transparent when I erased part of it, so that when one layer went over the other the bottom layer would show through the erased part. Unfortunately this doesn't work for some reason, I don't understand why it would go white and not transparent ?!? I've tried playing with the opacity, but they makes the whole thing go transparent not just the erased bit, so that doesn't work either.
Thanks so much for your help though, I really appreciate it.

Hmm, ive tried to play around with seashore before and I really don't know my way around it. Maybe try asking under the design and graphics forum, they might know more.

ok try this ...

... get a hold of the image that you want to have partially transparent, hit edit, select all, copy. Then, in seashore, hit "new image", and on the new pane that takes your "new image settings" specs for this "new image", select or check the box that says "transparent background" - now paste the copied image here. I did this, then created (and drew on) another layer under this primary image, when I erased a portion of the primary image, the remaining area of the primary image where I had erased was transparent and I was able to see clearly the underlying image. This strikes me as being what you need, let me know if it works for you.
If you erase part of an image and an underlying image won't show through, then that primary image that you attempted to erase through is not made with a transparent background.

.

... now, when you go to erase this image that you have created with transparent background, the erasure you make will reveal the transparent base to let something else show through.
You'll see once you do it, it is far easier to do than to explain.
