There is, from what I've heard (I'm no expert, so don't quote me) something called a 'pen tool' - basically you cut out your subject with a (very long) series of straight lines connected by points - kinda like a super-precise version of join the dots - you click to creat a point, go round the entire subject, and finish off by pressing enter. during the time you are performing this action you can zoom and scroll and there is no problem.

As I said, I'm not sure whether all of this is true - it is what I believe to be true, having heard a few snippets from people who actually do edits (I don't) - people such as mic....

Like already stated the pen tool is a very good way to cut out the plane... However I use something called the 'background eraser' and simply it will only erase a certain range of colours within the area of the brush tip... Wink

So as long as you have a constant background and it is a different colour from the aircraft it gets rid of the background in no time... leaving the plane all by itself! Wink

You get this...

To this....

Hope this helps...

hmm, know how to do that in GIMP? and also, what if the background wasnt as even as it is there (before i used a 'set transparent' tool on this program which removed some of the background... but this looks more effective)

The pen tool is the most precise way to select a subject. After that it's all about layers and layer masks ..... which unless you have photoshop or paintshop you won't have to worry about them.

Paintshop also has the pen tool right?

Yes but a good way to extract an aircraft from a plain-ish background with Photoshop (although not always very accurate) is with the Filter > Extract option Wink
