While we're mulling this over I'd like to share a tool you might add to your toolboxes in evaluating picture details. I've seen people here tweaking color balance, contrast, white balance, gama, etc on photos in order to try to see details hidden to the eye in the raw photo. Those are all great techniques and very useful for seeing things differently. But there are other techniques that force your mind to process what you see differently.
Our brains are amazing machines that do a lot of work without us even realizing it. It is constantly looking out at a 3d world and trying to make sense if it, and make judgements about it, using two 2d sensors which are our eyes. And it does this through superimpossing two images in our minds eye using rather limited stereo vision but in the process its making a huge amount of assumptions based on our prior experiences and what it considers "normal"...
In the field if engineering in which I work, we are often times looking at images of macroscopic or microscopic size. The problem here is when your brain is looking at something that has no external references for what is up or down it will assume things based on which way the light is coming from. And it will normally process the image assuming light was coming from above, from the sun, or a ceiling light, etc. But in a microscopic world the light could be coming from any direction. And when this happens what you see as something raised can in reality be a depression. However if you rotate the image 180 degrees your brain will automatically reverse its assumption! Its really quite a neat feat. But you can use this technique to force your brain to not see something different, but process what it sees differently. And by doing so you can end up seeing things you never saw before in the exact same image. Also, because a picture is a 2d image your brain also makes assumptions that what the camera saw in a single image is the combination of two images like it sees with our eyes. So when the brain sees a 2d image it may assume depth on a photo very differently that if it was looking at the same thing in real life. So take that into consideration too. So rotate your photos 90 and 180 degrees and look at them with fresh eyes. Also mirror images may some help see things differently and last try using a negative image view which many software editors can do.
I hope this can help someone find the next big discovery here!
