Use the quickmask method. Or you can use a combination of paths (for large smooth areas) and quickmask. There is no "royal road to rendering", you just have to practice. And yes, it can take a while.

But never NEVER do my mistake: BEFORE to save the selection, or copy&paste the render be sure to have quickmask SWITCHED OFF!
Or you will lose all your work :s: (and puzzling your mind becouse Gimp will act crazy till you don't close and reloload it.)


At least this happened to me (see http://www.gimptalk....em-16823-1.html)

You can try to replicate the bug to your own risk if you wish...to me once was more then sufficent!! :c:

Hi,

I am completely new to Gimp and I stumbled across this thread which is covering exactly what I am currently trying to do. I have a book cover that I am trying to clean up: it has a white background but there are dirt and wear marks that have discolored the white. I tried to do the Alpha Color change but those discolorations stuck around as I guess they were too different from the white to register as such. Can anyone here tell me what the best method of those listed would be to handle this? I have been playing with the layer mask method for the last hour or so. I am worried that this won't work as there are multiple section to "clean up". I guess I would just like any input on what method any of you experienced users would recommend I use on this method. It doesn't have to be perfect even but it will also make good practice. Any thoughts?

Here's the image:

Hi, I have a question here..how would I cleanly remove this background? The simple add transparency and delete with magic wand doesn't work on these kinds of pics?

Ok I've learned the quickmask method and fixed my problem i wasn't inverting it that is why that was happening and as for the kid with the basketball player your best choice for removing it would be the paths method specially since your render seems be more of direct angles instead of curves. A tutorial for the paths method can be found here:

What is wrong with the foreground selection tool? Works for me, maybe needs a bit of minor work after, but saves a lot of time when trying to separate a large object.

OK, none of the links given in the first post work, and neither does yours!

So, now what?

Didnt think it was worth starting a new thread.

I get the image edit, ie paths tool and so on.

But i'm still left with the outline of the original layer of the image.

So i've got an image from the web, cut the bit i want to use, but i'm still left with the size of the image(an out line) which i cant get rid of, and affects my project when i come to map.

Help me please!

Just throwing this out there, if you have a solid-color background, just either color-to-alpha that color, or use the color selector tool to erase it. If that color is in your render too, then after you cut out the background color, alpha to select the render, make a new layer, fill the selection with the color the background was, and move it below the render layer.

My best tip on removing a background is by photographing against a green screen. Then using Photokey 3 Pro software to remove the background. Believe me, it's the easiest way, if you can start by making a new photograph.

Yet another method I use is if you have the right kind of image, you can mess around with the contract, then use the threshold tool, then hopefully the shape of your render will be black or white, and the BG the opposite color. Then you color select the render, and fix it up however you want, then you have the shape of the render selected, so go to the layer with the actual render, copy, paste, and there you go. (:

I'll help you on two conditions:
1) I try to help, but I don't know everything, and I'm not an expert, so I might not be able to fix it.
2) If I don't respond right away, it not that I'm ignoring you, I'm just busy or something.
