you shouldnt have to invert or change contrast to see a true bfp line.in doing so you end up seeing things that arent actually there.
I totaly disagree with this aswell!! Its so hard to get a camera to show wat ure seeing!!!! I still cant pick up my bfps on my ics even with tinkering with it yet clear blue digital says im pregnant, so i say theirs nothing wrong with inverting or uping the contrast on photos so that wats their is easier to see!!!!you shouldnt have to invert or change contrast to see a true bfp line.in doing so you end up seeing things that arent actually there.
I've upped the contrast on this pic, and the line is pink, it's not a shadow without colour ... so I'm going to test again each morning with fmu and am going to keep my fingers crossed that the lines get darker
