The ladies that are tweaking test please stop doing the picture in the negative color. Why? Because if there is a line there regardless if it's a faint line, evap or a indent it will always show up in the negative picture. Play with the color so you know either it's a evap (most evap are gray or white) indent, or a faint positive. Which a positive will have color. By tweaking the photo you should be trying to pull in more color in the test line to see if the line is really there and also has color. It breaks my heart seeing the tweakers posting the negative picture and saying I see a line when that line could be a evap/indent. As you see in the picture a evap/indent is showing just like a faint positive is showing.

Good luck mama's and baby dust to all.
