To answer your literal question, there are a few areas where GIMP can be better than Photoshop. It's not particularly common (usually, at best you can expect them to do the job equally well), but it does happen. Off the top of my head (and keeping in mind that it's been many years since I last used Photoshop), here are a few examples:
As a historical ...
Before I start, just to let you know I'm a happy and frequent user of GIMP, but I also have an Adobe CC account, and use the latest version of Photoshop, which I also enjoy using. I'm not a fanboy of anything.
GIMP is not Photoshop, and it doesn't really try to compete with Photoshop. It's not commercially developed, and so it's not a commercial competitor,...
These four options define how to scale the image. Each option describes an algorithm used to do this. See image sampling.
None: The nearest-neighbor algorithm is used. There is no smoothing after scaling.
Linear: Touching pixels average their values.
Cubic: Touching pixels average their values so central pixels maintain the most value.
Lanczos: Pixels are ...
An .SVG file IS a source file. It isn't layers in the Photoshop/Gimp sense but it absolutely can be picked apart. Use an SVG editor - that would be Illustrator or Inkscape.
Alternatively, if you want to get real crazy you can open the .SVG in any text editor and look for the values you want to change which for colors would be in Hex format #nnnnnn
Indeed you should perform right selection.
Select->Color Range and click on the spot colored with color you want to select - you will see the change on the preview screen.
Also, you can choose the color from sampled colors drop down menu
Fuzziness should be set to 0.
If you press SHIFT while selecting (you can also click Shift and drag of the image) ...
It won't be perfect but you could use a Polar Coordinates filter (Filter → Distort → Polar Coordinates...) set to "Polar to Rectangular" on the image:
The result will be "straight", but will be distorted so you'll at least need to adjust the height to compensate. This is after transforming the layer to 50% height:
With a further bit of correction ...
I think printing something off and then re-scanning it could work very well, but you may find that even an old laser printer might not give you the halftone that a news paper printer would.
I had an experiment in Photoshop. I used this photo:
Image > Mode > Grayscale
Put the file in 8-bit mode if it isn't already
Image > Mode > Bitmap
Here you can ...
You'll want to use the Pencil tool instead of Brush tool. It allows you to do pixel level edits without any anti-aliasing (the fuzzy area). It's located below the Brush tool or can be accessed by repeatedly pressingShift+B until it cycles around.
Set blend mode of copy to Multiply
Filter > Blur > Gaussian Blur set this to 1 pixel.
Duplicate blur/multiply layer 3 or 4 more times.
Choose Merge Visible from the Layer Panels menu
Filter > Other > Maximum - set this to 1 pixel.
Image > Adjustments > Levels to tweak things a bit more....
You will probably need to go in with ...
The world is full of magic things, patiently waiting for our senses to grow sharper. (Yeats)
Lab, which I often read as Lab but is properly said L-a-b, is amazing. It makes the world a more colorful place. If you've ever taken magic mushrooms, its kinda like that. With Magic Mushrooms subtle color differences can become far more apparent because ...
Since many have said most of what I was going to, there is one situation, somewhat specialized, that GIMP can handle that Photoshop could not.
I do astrophotograpy, and if I want to process the RAW images from the telescope's camera (not a SLR/DSLR attached), GIMP can process these files while Photoshop can not without a special plugin designed jointly by ...
A JPG is a raster image with no concept of layers or history or anything of the kind that would let you revert it to a previous state or remove anything leaving what was underneath intact.
The only solution is to find the original file (version history in Dropbox or Google Drive comes to mind) or some other non-graphic-related technical solution.
This can be done. But not done very accurately. There will be some warping and distortion when you straighten it out. That said, here's what I would do.
Cut the piece into 3 separate pieces using your favorite selection method. I suggest the pen tool, but you don't really need to be that accurate.
Put each piece on it's own layer.
Then use the Puppet Warp ...
It's the Radial Gradient Tool
Double click on layer or right click and select Blending Options.
Check Gradient Overlay and change mode to Radial as shown in image.
Drag your cursor above image to change the location of your gradient and change scale slider to define spread area.
For further explanation, refer to the official tips
Hope you get the result ...
You can not compare GIMP and Photoshop because they do not represent the same category of tools.
The world is full of pixel manipulators that have
faster interaction speeds,
easier to use,
But this misrepresents Photoshop. Photoshop is mainly about its color management engine and its print related feature, ...
I've taken advantage of most of the things listed in other answers but there were a few which I didn't see highlighted...
Really flexible keybindings
Also called keyboard-shortcuts or 'accelerators' depending on where you're from, I found that – at least in CS3 – Adobe arbitrarily limited which key-bindings were allowed for certain functions.
To me Photoshop + Illustrator combination works best:
Go to: Image > Image Size...> and resize it to 200%. The resize scale depends on the image and is to make sure that the shape blur used in the next step is not too big.
Go to: Filter > Blur > Shape Blur... >. Use minimum blur radius (5px), select Shapes object group from a ...
Here's what I managed using GIMP; I believe all the steps should be possible in Photoshop too:
(optional) Convert image to pure black and white, using Color > Threshold with the threshold at 128.
Apply a very small amount of Gaussian blur; I got best results with a radius of 0.6 px, but you may wish to play with different radii.
Apply Color > Threshold ...
If you mean one solid color over a transparent background then it is easy:
Set the alpha lock for the layer (checkerboard icon in the "Lock" line at the top of the layers list)
Bucket-fill the layer (without any selection) with the required color, the alpha lock will ensure the opacity of pixels isn't changed.
Resizing and scaling as synonymous
Resizing is an intrinsic change in the size of the image. Changing an image size from 1000px to 500px is resizing.
If you change the size from 100% to 50%, or 2:1 is scaling... which is the same as before.
Resizing is normally performed on an image manipulation program, like Gimp or Photoshop.
This resizing affects not ...
In 1973, it was hand drawn/painted.
There's no reason to believe he didn't merely draw it all. And there's especially no reason to believe he didn't specifically hand color the image how he wanted. It's kind of insulting to him to think he couldn't have possibly drawn and colored the image. Of course he could have. That's what artists did in the 70s before ...
SVG is just an XML file so you can edit it in any text editor.
If all you have is a solid shape with transparent areas cut out of it then it is probably a single compound path.
Take this for example:
The SVG code for that looks like:
<svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px"
I have used both. Like you I had several years of Photoshop use before using GIMP. The thing is that we tend to forget how much of a learning curve there is with Photoshop. GIMP is very powerful but also has quite a learning curve. The way you do things on GIMP is different than the way you would do them on Photoshop.
The only thing which I think may ...
The easiest way you can do this is by unchecking the contiguous (marked yellow in screenshot) location when selecting the white colour with magic wand. This will select only those areas which you want. To get exact colour or colour range you can set the Tolerance as per your image.
Here is an screenshot with my imaginary image.
Laser printing, manual distressing and scanning would absolutely be an easy straight-forward method.
Barring that, you can (obviously) remove color, then lower contrast and overlay some noise and possibly a texture file to create a distress. I don't know that I would specifically use the Halftone filter, you could. However you may get better results with ...
