If you are using RAW files to take your pictures, you could do lots of modifications on your pictures after your pictures are being taken. Most people use Photoshop (PS) as a tool. I had used PS version 7 for JPG files from around 2002-2014. I had also used Nikon Capture Editor 4.3.0 for NEF files from 2005-2014. I haven't used them much since then. Yesterday I just tried Corel "After Shot Pro 3" and find that After Shot Pro 3 is much easier to use than PS and Nikon Capture Editor. Sometimes, just one mouse click, you work is done. I did not have to use youtube to learn. When I was using PS, I had to buy several books to learn how, though my favorite book was only one titled "50 Photoshop 7 Techniques". That is the difference! Among other things, it is much cheaper than PS Elements and Light room (both are aroung $100, Photoshop is $240). I bought my After Shot along with Corel Painter for around $20 in April, 2022.
Here is how to use After Shot:
1. Click on the installed program icon 
from After Shot, you get:

The following is with Auto Level ON but with Sharpness to the maximum level:
9. you could save your work, click on File, then click on Export, you will get:
10. Click on OK, you will get your picture in the same folder from your RAW file, notice that you now have a JPG file in your RAW folder:
11. go to File than click on Exit. (I could not figure out how not to exit and edit another file, so I exit the program instead).
12. One more easy treatment: change the angle of your picture. Using the same steps above from item 1 to 10, you could also change the angle of your picture from this:
to this just by moving you cursor along with the ball in "Straighten" in Basic Adjustments:
with Auto Level on:
