You guys are wizards with PS et al.
The differences you make are outstanding. I think I'll have to really get to 
grips with PS. When I was  a full time programmer - we (programmers) spent a 
lot of time hand-editing images (usually computer generated rather than 
photographs) but it's not something I've really done (editing images I mean) 
for a long time. I think the software tools nowadays are amazing and I know 
it takes a lot of skill and talent to get the best out of such tools.
So it's kinda weird for me - I've been working with digital imagery of some 
kind or other since 1981 - but I'm new to digital photography and editing 
digital photographs. Over the years, I've written more multi-media apps than 
I care to think about - amongst them was a program suite called KAOS which 
could edit, view and play every form of media at the time of writing. With 
it, you could view, edit, play with text, graphics (BMP, TGA, JPG, TIFF, 
GIF, PCX, MSP, PNG, GEM, Windows meta-files and other vector graphics, etc. 
etc.), all office docs (Word, Powerpoint, Excel, and Access), MP3s, wave 
files, Amiga MOD files, SND and AU files, MPGs, AVI, MOVs etc. etc. - and it 
had a web browser, email program, LAN chat program, file manager and even 
had its own programming/media-authoring language with which you could access 
and use the various Windows APIs (e.g. MCI API) using simple English-like 
text scripts. It had it's own text editor, paint program, CD and DVD player. 
I wrote it as a one-for-all media requirements app. It got me a boatload of 
distinctions when I did my IT degree. But I admit, I'm a million light-years 
away yet from what some of you can do with PS et al. But it is weird because 
I've written software that manipulate bitmaps - rotate them, invert them, 
emboss them, convert to grey-scale (and metallic), convert between formats, 
enhance a little (sharpen or blur, etc.), enlarge, reduce, etc. etc. But at 
the moment I wouldn't have a clue how to do in/with PS, PTLENS, etc. what 
you guys do.
I know I'm going to have to change how I do photography and work with images 
and that's one of the reasons I find groups like this one so useful. In the 
short time I've been in this group _ I've learned far more than I can air 
I was going to scan 1000s of images from negatives - but the scanner doesn't 
give anything like the results I want. So at the moment I'm just playing 
around with the 300D - getting to grips with it b4 I take it out to various 
locations I have in mind. My impressions so far is that digital photography 
is a surprisingly different kettle of fish to film photography - and opens 
up entirely new vistas. The quality of shots by digital photographers on 
this and other groups sets a high standard to aspire to.
Just thought I'd say thanks guys :)
