First thing you could've done in that room was cover up them Windows an try to limit that kinda indirect light also sometimes it's better to just take the cued outside an take pictures in the. Direct sunlight an work the camera so you can eliminate the glare. If you cannot see the screen good on your phone put on a giant hoodie so you can block out the sun an get more of the cameras light to illuminate the screen don't use a cellphone generally unless it's a Smartphone an it's got s good camera an you select THR highest grade picture you can select.
Digital Cameras are the way to go an also at the green highlighted Threads in this Section of the forum there's an article about taking better pictures. I'm needing to read it myself
