Which is better PrintShop Deluxe vs. Adobe PhotoShop
In Photoshop you can easily go back, change what is drawn, recolor drawing, keep elements on separate layers and hide them, delete at any time ...
Photoshop Elements is Photoshop but with less features, so Photoshop is better but it is professional level software. For home use or to get started Photoshop Elements is OK.
PS 7 is one of the older versions of Photoshop, before Adobe's merger with Macromedia. Photoshop CS4 is the current version of Photoshop (soon to be replaced with CS5 this summer). While the two have the same developer and history, CS4 is a much more advanced version of the program. Tasks that required separate programs or plugins (mini-programs that you can buy that run within PS) with PS 7 are now standard in CS4.
Yes it is, contact customer support for details, current version is CS5 and is much better then CS2.
That question is kind of hard to understand, but I'm assuming you mean which version of Photoshop is the best. That depends on what you want to do with Photoshop. Basically the newest version Adobe Photoshop cs5 is the best one because it's the newest and it's got the most options
Adobe Photoshop is better for editing photos, naturally. Adobe Fireworks is better for graphic design such as logos.
No but they colaborate. Photoshop have more features but Lightroom have better cappabilities for photographers.
cs5 is better
Photoshop is a commonly used professional image editing software. I would recommend this.
for better drawing
Photoshop them after they're taken.
