I've had similar struggles for sure!! Do you use photo editing software? I use Gimp (which is free) and love it! My suggestion is to edit the curves section. This has a different effect than adjusting the brightness/ contrast. If you want to send me a pic in a pm I can edit it with curves and message you back with an edited pic. I would do it on the board but it's against the rules/ laws to post someone else's pic and all.
