Remove flaws from AI generated images

Hello guys,

I have started generating images with the Midjounrey software a few weeks ago and really like the results I get from it. But unfortunately many images have some flaws. Usually there are blue or pink shadows on the right side of objects. 

I attached an example image, where there is a blue shadow on the right side of the cheek.

The images are mostly pretty great, but these small errors bother me. I don't know much about image editing. Is there a way to edit these things out? Preferably with a free to use software like gimp or so? I know programs like photoshop and other can get quite expensive.

Thank you for your help :D

A dramatic image, and the short answer is 'Yes'.

In Gimp, and the other full-fat image editing applications, you will find a tool called a colour sampler, it usually looks like an eye dropper. This copies the colour from either a single pixcel or the average shade of a small group of pixcels and applies it to the paint brush tool which you can then use to over-paint the offending area. You will normally have to magnify the image considerably - zooming in - so that you can see the area you want to work on in sufficient detail, often up to the point of seeing individual pixcels. For larger areas there are usually techniques for blocking out areas in your preferred shade.

Be warned that while making changes like this can be very satisfying and effective it can also be quite tedious, especially if you get down as far as re-shading pixcels one by one !

First, I'm a Photoshop user, but I assume that other decent bitmap editor programs will have the same tools.

For small details like this I use the clone tool, and soften (feather) the edges; that way you reproduce the identical color of the surrounding skin tones and the "soft" edges are not noticeable. If there are a couple of noticeable edges, use the blur tool to ease them out. 

I am a long time professional Photoshop user and recently switched over to Affinity Photo. It is very much like Photoshop but costs a one-time fee of $50. It does everything I need it to do and was designed to attract Photoshop users.

That being said, I could be using GIMP and get the same results but I don't like the "feel" of GIMP.

The fact is, working with an advanced photo editor is a daunting process to learn. A beginner would need at least 40 hours of study just to learn the basics. Over time, a user will develop their own process that get their work done. One of the most requested questions is how to remove a background. When I remove a background I study the image and decide what tools I need based on the image and background. There is no one way how to do it. It takes time to develop proficiency.

I recommend you get started with GIMP and spend time with some of what must be millions of available tutorials.

Let me know if you have any questions and Good Luck!
