Pure White Backgrounds: What a leason I learned!
Of course isolating an object on a white background, I always try to touch-up on Photoshop. I'm still learning all of Photoshop's amazingly helpful touch-up functions but this one is the latest lesson learned. Only after my "Budget" picture was posted on my portfolio did I notice an odd, gross looking light, very light gray triangle shape on top of the measuring tape. Then my eye was drawn to other smaller areas randomly around the rolled-up dollar bill. What is that I asked?? I tilted my laptop screen in every angle and with each twisted it showed up worse. After awhile, every time I signed into DT I could only see that hazing gray on my picture. Now, after the file has been viewed 3 times and no bites, I had to be concerned a little. I went back to the original and after tilting the laptop screen again, there it was!
I'm sure to some, you're shaking your head and probably have experienced this mistake before. But when I did my touch-ups in Photoshop I had missed those few areas with my brush and the original slightly grayer background was still present. I took the picture back into my design area, set the calculation tab, opened my channels, darken the levels in my alpha layer, and there they were! Those areas I forgot were just shining bright, mocking me. Well, I took care of them and resubmitted my picture with a very apologetic note to the editors/reviewers. As I writing this I am still waiting to hear back on it's approval.
Being a researcher by nature, I scanned the internet for every possible way to completely isolate an object and create a pure white background. And probably without me having to say, there are multiple, multiple ways of doing this. So I put this out to our community and ask what techniques you guys use to double, triple check that your isolated photos have a crisp completely white background before submitting?
