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 ...
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) ...
My answer is very much like the previous answer. I still provide it because the above did not directly lead to success.
So you have two files: file1.jpeg and file2.jpeg. They can be different formats than jpeg, and they do not need both to have the same format. So file2.png would be fine too.
As a matter of background you can think of the Gimp image as a ...
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 ...
In my opinion, the Magic Wand tool is about the worst method for extracting a background in 95% of all use cases. Unfortunately, I realize it is the "go to" method for many users. However, it's not often the "best" method, in fact it's among the worst. The Magic Wand method can work for hard edged objects without any cast shadows. But ...
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 ...
One of the problems with the example image is that it's a very noisy jpeg with with noticeable jpeg compression artifacts. It would be better to start with a RAW image file straight from the camera. The better the image quality is to begin with, the better the result will be.
Anyway, first thing I'd do is duplicate the image, turn it into a Smart Object, ...
There'a an older answer which covers a part of it, but I have an alternative and a little to add, too.
At first the noise: It's something that cannot be skipped. The needed edits would explode the noise to intolerable level. It cannot be removed from all of your existing image with noise removal tools because the face and the background would lose details, ...
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 ...
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.
I agree with the OP's opinion that selecting the gold trim is an interesting solution. We want to take the blue components in the original image and turn them red without changing the blue components in the trim.
Here is an approach that uses GIMP's layer masks and color channel extraction to separate the gold trim from the rest of the image so we can ...
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 ...
GIMP's Rotate Colors
I think Rotate Colors is a good tool for this job. Open the image in GIMP and choose Colors -> Map -> Rotate Colors...
Then choose a blue slice in "From". I chose 184.8° to 273.1°. Then choose a red slice in "To". I chose 327.2° to 47.4°.
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"
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 ...
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 only ...
If you have Photoshop CC, then you could use the Select and Mask functionality to refine a selection made with the Magic Wand.
Select the Magic Wand, deselect the "Contiguous" option, set the Tolerance to 20, and click on a white area
Select > Invert
Click on Select and Mask, set the View to: On Black, at 100%
Select the Refine Edge Brush ...
Alpha blending is:
Cout = α * CFG+(1-α) * CBG
Now there are two alphas on the image: a full transparency and the object transparency. The first order of business is to calculate the full transparency. Because we know the color and structure of the checker, we get a system of equations out of two pixels that have the same color.
C = α * CFGdark+(1-α) * ...
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.
