If you want to be in full control of the photo, you have to "take"
control with a photo editor.
This means never uploading directly from the phone or camera.
The first step is to move the photo into an editor program. Popular photo editors are Adobe Photoshop or Lightroom. I use a program called "ACDSee". A photo editor allows you to make numerous adjustments to the photo. When you have it looking just right - save it, then you can upload it to the Forum - or anywhere else.
Bottom line - get, and learn to use, a photo editor.
