They'd better make the alpha channel an editable channel. That's all I have to say.

Oh, no wait, I also have to say that they'd better implement an "additive" blend mode. (Unless they already have that and it has some obscure name? I hate how the names of their blend modes give no clue as to what's happening mathematically.)

Damnit! I *just* bought Adobe Design Collection....

Text on a path!

Finally, for those of us who can't do d*ck in Photoshop!

photoshop 8 weeee..maybe im gonna buy this one, though i am not sure about it!

Slime, in what way do you find you can't edit alpha channels?

I haven't run into where you couldn't? Is is something that's mode dependent. I mostly use Grayscale, CYMK, LAB, and RGB.

I use most tools to edit any of the channels, needed alot when you do model work for hair masks. Expecially in the days before layer masks. If you can't edit a channel is may work to try loading the alpha as a selection and adjusting it as a quick mask instead.

Additive blending would certainly make my day. The only way of getting something close is by using multiple copies of the same layer stacked on top of each other with different blend modes, opacity levels and blurriness (colour dodge, screen and overlay combos worked wonders for the twilight-muse images I did a ways back) but it's impossible to remember exactly what settings work and what don't.

Although, for the most part the changes look quite good IMHO, but that's mainly because I've been doing a bit of video work recently. If it wasn't for that I probably wouldn't even consider upgrading (like I have the money, I'm stuck with an academic version, i.e. non-upgradeable <- is that even a word?).

Slime: I don't understand in what way you can't edit the alpha channel or the mask of a layer. When you ALT+click on a layer mask in the LAYERs pannel, you'll see the mask in B&W but you can also edit it as a normal layer i.e. use any tools / filters / transformations ...

Regarding the additive blend mode, I haven't done some advanced tests but I think the LINEAR DODGE mode in PS7 is a simple additive blend. Unfortunately we're stuck with PS5.5 at work so I can't check that right now. BTW I share you opinion about the names the blend modes. It would be really interresting if Adobe explained how the blend modes works.

I'm saying, one should be able to edit the alpha channel just as easily as editing the red, green, or blue channels. It should be in the channels pallette. I don't want to have to change my selection to do it.

Haven't alpha chennels always been in the channels pallette? I seem to remember them there from as far back as photoshop 4.

Photoshop 6 here: I make a new layer, paint on it with the airbrush, and in the channels pallette, there's RGB, Red, Green, and Blue. No alpha.

Painting with black or white on one of the channels affects only the non-transparent areas of the layer; there is no way to directly modify the alpha channel when editing channels individually.

Slime: Oh. I see. Indeed Photoshop considers the alpha implicitly. But it'd great to see it explicitly appear either in the alpha channel ( which is closer to the internal representaion of colors ) or in a mask ( which always exists but is only made available when the user asks for it ).

Ok, we have PS 7 now, what no. is Photoshop Pro? I'm getting so confused.
