Hi Mark,

I have been using PictureIt for my photoediting so far.
Now I am thinking of moving to Photoshop 7.
What is the memory requirement for it ? My current machine has Windows ME with 256 MB of ram.
I am planning to have it upgraded to 512 - that is the maximum that old machine can accommodate.
Do I have to move to other machine for memory or 512 MB would be enough ?
Other point is I am not professional photographer, however, like to play with these tools.
Would PhotoShop Elements be suffiient ?


Thanks

OK. What scanner are you using? (what resolution ate you scanning at?)
What image processing software are you using?

For images I intend to print I always scan at full resolution (that's
3600 dpi for my Kodak RFS 3600) in 16-bit color (48 bits total or 16
bits per color). This results in 90-92 megabyte files.

I have Photoshop 7 so I can do most of what I need to do in 16-bit mode
before saving to 8-bit for archiving and printing.

First, use a blower of some kind to get your slide as clean as humanly
possible.

16-bit mode with my scanner gives basically a RAW file of what the CCD
saw, so it's usually quite dark. My first few steps in Photoshop use the
Levels adjustment to get the image *roughly* where I want it to be.

My first adjustment is of just the bright (right-hand) end of the
histogram. Then I fine-tune the image rotation (it's never quite square
in the slide scanner) and then crop out the black edges around the
border (I make sure my original scan area is slightly larger than the
viewable portion of the slide).

At this point I can be sure that whatever shows up at the left-hand edge
of the histogram (dark end of the scale) is actually dark parts of the
image, rather than the unexposed border (well, slide mount, actually) so
I use the levels adjustment again to set the darkest point. Then I use
levels a third time to set the mid point to *approximately* where I want
it.

Save after every step :)

The next step is removing dust specks with the clone tool. If you (and
your lab) have been careful this won't take much time - I recommend
doing your scans as soon as possible after having your slides processed.
View the image at 100% magnification and clone out those little black
spots.

At this point you can decide how tricky you want to get. Taking the
simple route, you just make final tweaks with the levels tool, convert
to 8-bit, save and you're done. I recommend doing a *little* sharpening
at this point. I sharpen enough for a 12 x 18 print; that's as big as my
printer will do and pretty much as large as I care to go with 35mm film
anyway. Smaller print sizes will require more sharpening and that can
always be done later at the time of printing.

Remember that with scanned film, sharpening is always the
*second-to-last* step before printing: After sharpening you should do a
second search for dust specks that you didn't catch the first time
around (the sharpening will inevitably bring out some that weren't
visible, or weren't objectionable, before).

For more advanced techniques...

Photoshop for Photographers, the book that several others have
recommended.
