GIMP :: Erase Background Of Different Photos And Combine Them Into One Image
Aug 17, 2011
what I'm doing right now is trying to erase the background of many different photos and combine them (as different layers) into one image. I finished two layers and just as I was about get going on my third layer, I made a mistake and did something to the threshold. I didn't remember what I had it on (well, it was on the default setting) so i put it back to 141 and decided to continue with my work. but then I realized that I couldn't select anything.
I've been trying to use the Eraser Tool to erase a background sky and it won't erase. The Alpha Channel is turned on, the Selection Tools work, but the eraser does nothing.
This is a kind of ”HDR”-process done in just 8 small simple steps using GIMP.
What you need is three identical photos where each one has its own exposure – one normal(1), one under exposed(2) and the third over exposed(2). On my Canon 550D this is done with the EAB function. When the process is finished in GIMP the best exposures of each image will appear. The principle for the process is to use the fact that all dark areas in a layer mask will create transparency in the current layer.

1. Open GIMP and Archive – Open: image (1) 2. Archive – Open as Layer: image 2 3. Layers dialog (right click the layer 2) - Add layermask 4. Add mask to layer dialog, choose Grayscale copy of layer and klick Add This mask will filter all dark shadows and make the layer transparent in those areas. 5. Archive – Open as Layer: image 3 6. Layers dialog (right click the layer 3) - Add layermask 7. Add mask to layer dialog, choose Grayscale copy of layer, mark ”Invert” and click Add This mask will filter all highlights and make the layer transparent in those areas. Try mode Normal or Addition 8. Merge all visible layers.*

10. Now you can threat and manipulate the image as one image and save it.
*Further more; before merging you can adjust levels (Color - Levels) for each layer mask as well as opacity (Layers dialog) for each layer to fine tune layers for the final image.
when I anchor the layer face over the background face the floating selection disappears which means I cannot work on the layer face and therfore am unable to erase the layer face into the background face,this is on gimp 2.6
I am currently trying to combine a color photo frame with a black and white image, but every time I open the frame in "open as layers" the frame turns to black and white as well as the photo. I have no problem when using color photos. Is there a way that I can do this so that my photo frame remains it's original color with the black and white photo inside.
I can create a signature with image and text as in attachment, (not sure even did that) "DARN"but would like to be able to type directly on a jpeg or gif etc.
I have made a selection on my photo and erased the background making it transparent. Now when I fill the background with white, I see portions of my original background showing through. How can I easily reselect the background and erase properly? When I use with the Quick Selection or Magic Wand tool, it doens't select all of the transparent background. I seem to remember a tip where I used another feature of CS5 that darkened the transparent background so much that it was eay to erase the missed background.
I need to remove a picture of a horse in the background and replace it with a picture of a fence similar to the rest of the picture. I know how to erase the image using the lasso tool and the magic wand. How do I clone part of the background to replace the erased image and then blend the two pictures together?
trying to separate non-contiguous letters from a background so as to make the background transparent. I've used various methods including the gimp tutorial referenced above, and am having problems both selecting everything I need and with the transparency.
When I use the foreground select tool as in the tutorial, I can select the first line, 1812, but not the next two. Color values off some? Anyway, after successfully selecting at least the 1812 part, I do the next steps: invert the selection, add alpha channel, del background; and end up with a transparent background and a 'kind of' transparent 1812. If I try to save it as a png and open it in any other program it's just empty or black.
I have an image that I want to extend the background on. So basically, I am making the people smaller, but the background larger..if that makes sense? I'm trying to make a collage, and i want the background of one photo to be the background of my canvas. The background it just "grey-ish", but not solid. I know I could clone, or copy and paste a part of the image into the background, but am wondering if there's a way to "stretch" just a portion of the image maybe? Or if I could copy a small part of it, but when I paste it, change the shape or size it's being pasted into?
Before I pass along to you my request, I'd like to point out that I have watched tutorial, after tutorial on how to remove an image from a background. Every thing goes great, "step by step", (my project compared to tutorial) right to the final procedure. Then my image either turns "white/black", or disappears (lets just say the project does not pan out compared to tutorials).But everything is "fine", right up to final phase. How to do the following....
1. Extract an image from a background (any kind) of background.
2. Instruct me how to take the extracted image, and "save" it to file, to use it in "another" project, at a later time.
3. How to take an image (for instance, a large hole in a tree) and take another image, and place it in there. Inside this hole in the tree, I want to take an image, and "blend" it into the hole in the tree. Another wards,I don't want to just place a vivid "sharp" image into the hole in the tree, I want a " halo/gradual fade out from tree, to a gradual fade in to object placed in tree. I hope you understand my description. Basically, going from a sharp vivid image, to a gradual blending of another image in hole of tree.
What is the best way to paste an image into a background and have it blend nicely with the background to avoid jaggies.
I've been playing with the blur and smudge icon but then it depends on my eye and I lose resolution around the edges. I guess what I would want ideally is for a way to paste my image then have a slider or a way to select the amount of anti aliasing from image to background.
I have a set of window buttons in XPM format whose background I would like to convert to a blueish tone from their current gray. The problem I'm having is that after blending the button images to the intended blue tone they just don't look good at all.
To illustrate my point, here's the original (menu) button with gray background. Size is 12x18.
Then I took the following steps to try to apply the blue background:
- Manually edited the original XPM and removed the background (it's referenced by the '@' char.) - Opened it in Gimp and created a new layer. - Moved the new layer down so it acts as the background. - Applied a fill to background layer using intended blue color (#2d6fb5). - Set opacity of layer containing the button to 85. - In Colours->Hue Saturation set Lightness of layer to 100 so it blends better.
This is the result of the above steps:
As you can tell the result doesn't look good at all. Is there any technique I could use to make the buttons blend in to a more visually pleasing way with the blue tone I chose?
I have a 25 layer animated gif done. I also have a png of the same size with a transparent background. I want to run that png image on each layer so the background is animated while the foreground is not.
How do I add that layer to each one of the 25 layers of the gif so that the background looks animated while the foreground looks still? Version 2.6.11
I have attached the 25 layer background and the single top layer.

How to put an image on top of a background, or how to put images on the clipboard. How to do this for a very wet behind the ears newbie. I am trying to set up some different backgound that i can overlay images of cars on, for website ads.
how I can get rid of the bluish colour around the tree that I have removed the background from (see attachement). I first invert the image, then go to "Components", choose Monochrome, adjust the image to get the black background, and finally go to "Levels" to increase the dark background. However, when I had the mask and do the rest of the sequence, I keep getting the blue tinge of the sky around the object I have cut out.
I have an image. I want to add a solid color strip near the bottom . On top of the strip I want to add text .
Question: what's the best way I can get this strip?
In Photoshop, I would probably just create a new image of the length of the strip and then fill with the color I need and then copy and paste onto the image .
Below are listed the "step by step" procedure I'm going through, to isolate an image, "free" of any background. Each and every time, after removing the images original back ground, I'm left with a white back ground. List "process" by process..step by step, to "totally" isolate an image by itself (without any background) "whatsoever"!
I have now removed the background on (2) images. This is the process I go through in "order", and each time, I'm left with a white box in the background of my image.
"First" I load image.
Second I go to "layer"..
"Third" I go to "Transparency"
"Fourth", I click around image I desire to save...clicking on the "starting" point, till the ants start marching.
"Fifth", I click "select", scroll down and click "To Path"
"Sixth" I click on "Select", scroll down and click "Invert"!
I am having trouble getting the erase tool to erase part of an elipse shape in Corel Draw. I select the erase tool and click and drag across the part of an elipse that I want to get rid of (so far so good), then I release the mouse and an outline of the nib tool is left behind.
I added an alpha channel to make it a transparency.
I used the select by color tool.
I clicked white & removed.
I saved. I switched to eraser - but it is acting like I'm trying to erase something off the transparency layer and won't erase anything. I have the correct layer selected in the layers window.
I have a square image where I want to erase everything left of a line from bottom left corner to top right corner, so it will be transparent. How's that done easiest?
Wblock when run from the command line used to erase the entities selected, now it seems it does not, but the dialog box shows an option to keep or erase the selected entities.
Any variable name that controls this functionality?
