is adobe photoshop 7.0 sufficient for the general needs of editing
Also, I know elements is essential for image editing, but me being poor, is adobe photoshop 7.0 sufficient for the general needs of editing?
re:
If I understand what you are asking, the effect you are wondering about is usually done with a long exposure time rather than a post-processing thing. You can get longer exposure times by closing the aperature up nice and small, or adding neutral density or polarizing filters. Shots with extended exposure times also pretty much require the use of a tripod.

Elements 3.0 and 4.0 will have some features that are missing in Photoshop 7.0. Even Photoshop CS was missing some nice features that Elements 3.0 had (like Shadow/Highlight, Exposure, spot-healing brush). I may be wrong, but I don't think Photoshop 7.0 can handle RAW images, while Elements 3 and 4 can (though there are free RAW converters out there). If you have a licensed copy of Photoshop 7.0, though, I'd just pay for an uggrade to Photoshop CS2. If you have both PS7 and Elements, just use them both to see which suits you more.
