I'll take a picture of an object, let say a jar,and want to remove the background of the object ,any software?

i'll use this in making product brochure, it'll will be good if the background of the object will be change to white or completely remove, since i'll be just using a regular digital camera. pls advise me if there any free software i can download on internet

Use Adobe Photoshop CS 2, it's difficult to get quality without paying something, but if you want to have low quality editing you can use mspaint. mspaint can make white background, you just brush the background with white brush (hope your object is not complicated). Or you can use adobe photoshop trial version (30 days) I think it's enough for you to edit it, right? But editing using adobe require more skill and knowledge about the program. If you have difficulties, just e-mail or IM me, i'm glad to help.

photoshop cs2

Adobe photoshop Elements

Use the magnetic lasso

I have to agree with Megasparks0101. Photoshop CS2 is probably the best, but it's a little bit expensive.

UPDATE: Oh, and GIMP is good too. It's opensource (opensource = free) and close to the quality of Photoshop.
