As the other answerers have pointed out, GIMP misses certain features that you can find in photoshop. But then you are not limited to using only GIMP. I use the following free of charge programs: dcraw ImageJ ImageMagick Hugin GIMP dcraw allows you to have full access to your raw files, you can e.g. work with the raw data before any demosaicing is done. ...

Be aware that it's the proportion that is important here, rather than the dimensions. If you crop to 800x600px as you specify, then your image will only print at around 8.5cm across by about 6cm tall if you print at 240ppi resolution. I think it is the ratio of the long edge to the short edge that you need to remember, so 800x600px is a ratio of 4:3. In ...

Your camera takes pictures with 4928×3264px, 800x530 is a severely reduced size, which loses a huge amount of data. For printing, you should aim at ~300dpi, or at least 150dpi for a decent picture. 50/2.54~=19.69, so the full resolution width 4928 would yield about 250dpi, which is certainly ok. an 800x530px picture will come out terribly at this print ...

800×600 pixels is both far too small for printing at 70×50 cm, and also the wrong aspect ratio - 800×600 is a 1.33:1 ratio, but 70×50 is a 1.4:1 ratio. Your D7000 has a native resolution of 4928×3264; from that you can make a 1.4:1 crop of 4570×3264. You should be aiming to use as much of the pixel data you have as possible when printing - attempting to ...

This answer describes the fastest reliable approach I know atm, based on the answer by Ilmari Kanoren. It is semi-automatic; the automatic mask does not work for hard images like the one below because there are no edges in some parts of the drawing. This Gimp script automates steps 3 and 4 (note that Resynthesizer is required), so the workflow is just: ...

There's a way to do so in 32 BIT. In 32 Bit Mode Photoshop doesn't clip the subtraction between layers. I'll try to explain. Imagine 3 layers, the bottom layer, layer #1 has constant value of 120. Layer number 2, above it, has a constant value of 130 and it blending mode set to Subtract. The top layer, layer #3, has a constant value of 10 ans its blending ...

Duplicate the layer and invert one copy. With the curves tool flatten the bottom half of the brightness range. Using the levels tool, on both layers, set the input levels to 127, 1.00, 255 and the output levels to 0,127 finally set the blending modes of one layer to "Linear Dodge (Add)" and set the other one to "Subtract". What we have done is effectively ...

I use Wow! Tonal Equalizer the most. It provides Multi Scale Frequency Seprartion in one click. It is the closest thing to Wavelet Decompose in Photoshop. I hope one day for access to each detail layer. They said it is coming...

shootdotedit are used by a lot of photographers, especially in the wedding arena, and their processing and pricing would be a useful model to judge against. http://shootdotedit.com/pricing-plans/

I have used retouchers in China like these guys that charge $5/picture (and less for large quantities) and aren't bad for basic retouching. For more skilled retouchers $10/picture is common. For pros that are more on the "graphic artist" level the rates I see run $50-$100/hour.

Hum.... This is the photography forum, so I will take a photographic aproach. Of course for a perfect white you probably still need some post production tweeks. Instead of using a flash you can try using natural light. Avoid direct sunlight, don't stay too close to the window either, but like 2 mts away from the window. This is to reduce the diference of ...

The method I've used myself is similar to yours, but uses the Resynthesizer plug-in (for GIMP) or Content-Aware Fill (for Photoshop) to reconstruct the gradient: Create a selection that completely covers the drawing. You can do this by hand, or you can use high-pass filtering to compute a selection mask like this: Start by using an edge-detection filter ...

Edit: I wrote a Gimp script that does the steps below, and another one for Ilmaris answer. Both scripts are available for download on GitHub. The suggested way to go is this one. I’m answering this right here because I have been searching for a solution for quite some time and found a simple and working one. Let’s get to the result right away: Create a ...
