The two brighter ones are at ISO 800.
The background on the picture of Tonka looks odd, might be because I was standing in the kitchen, which has a different kind of light.
If you edit the pictures of Tonka, they look fine. Use Perfectly Clear in AfterShot Pro. But the noise removal blurs out the carpet as well. I don’t have a Neat Image license for Windows, don’t know if it would do any better, maybe.
Update Neat Image has better noise removal, it doesn’t blur out the carpet.
There’s the fixed image of Tonka. As long as you save the RAW file, you can most likely fix the image.
