Author Topic: Question on Giving Pictures White Backgrounds (Read 2029 times)

Blockoman · July 18, 2010, 06:33:29 AM

A while back I asked you guys what sort of picture editing program I could use to make images transparent, or isolate something in a photo and give the rest a sort of white background.

Here are some examples from Brickshelf (a LEGO gallery site)

Example 1
Example 2

So, I have a couple of questions:

What is the exact process to isolate that one part of the picture, getting rid of everything else?
Should there be a certain surface that I put the thing against, or does it not matter?

Wand and lasso in paint.net.
The perfect surface would be negative color to your item, or color as different as possible. And make sure it's not too shiny.

Damn, forgot to mention that I have GIMP and can't get paint.net

I'm sure it's possible there too, but I never understood GIMP myself.

It's a lot of meticulous work, but it can be done. Just pick out your object and make everything perfectly white that isn't that object. You can do this with the paint brush or pencil tools, or doing freeform select and just deleting the selection.

I use Real World Cursor Editor and occasionally GIMP. RWCE is actually an excellent program, it just lacks a few filters and extra brushes. I use it for pixel art.
