Hi, I've done a couple of tests and I'm confused by the results. The top one I did was the first one which I did Thursday night. I've done the bottom one this morning. I've had clear negatives before but never this. I've read about evaporation lines, some people seem to suggest the lines would be grey but some people say you can get blue ones. Is that what they are? Any help would be appreciated. I did try a digital test which didn't work at all.
