Open the "channels" window. This is like the "layers" window but instead shows the colro channels, one each for red, green, and blue. Click the "add channel" icon at the bottom of the channel list. Now this new channle is the alpha channel!Select that channel. Now in your photoshop document you will see a grey-scale image... well probably all black or all white right now. This is where you create the alpha channel. Black means transparent, and white means opaque. Grey means semi-transparent. Create this channel, then save the final image as a tif and you will have the alpha channel. Let me know if this is confusing and I can take some quick screen shots so you can see exactly what I am talking about  ------------------

You can also modify the alpha channel using the "quick mask" feature at the bottom of the tool box. It makes the alpha channel appear as a red (default) overlay on the image, like the old school "ruby lith" tape used on photo optical work.
This makes it easy to trace alpha effects on top of an existing picture.

Killer,
i tried to create alpha tifs a long time ago using Photopaint but they didnīt work in SDOE and IrfanView couldnīt open them too.
They only worked in the Corel stuff.
I suggest you to get a copy of PaintShopPro.Rendsburger

Seems like it wont work in Photoshop. I tried the method above and all I get is a blurred mess. It looks great in OPS though.Sv, could you post those screens or maybe a more in-depth how to. I'm sure I'm doing this correctly but I'd hate to think I'm making a stupid mistake along the way. IP: Logged |

learning to make alphas in Photoshop isn't easy as such, hell I still don't get shadows right LOL, but once you've learnt them they are pretty easy, I'm sure with SV's help you'll have no problems I'd not use anything but Photoshop IP: Logged |

Seems like the texture is fine. I think the SM file for the camo tent is the prob. I tried it on Tobruks camo tent SM and it looks fine. Thanks for the info anyway.IP: Logged |

Diego seems you've got help already 
Yeah Lothar, I'm an "old" repro-mounter/ photographer in the graphic buisness so I remember using the ruby opaque film manualy (miss the dark room sometimes, with that red soft light & black walls).
Photoshop is functionally the best image prog. I've used to date, extra fun with my 100meg + with GOOD filters I've gotten for free over the net 
Agree with rends though about PaintShopPro, It's the best free prog. that is getting close to Photoshop in functions IP: Logged |
