That’s great, to be able to go back and edit some old photos. I have quite a few folders of photos I’ve never processed, so when I’m feeling like taking a beautiful picture and it’s not beautiful outside or I don’t have any traveling on my schedule, then I like to go back and do some editing. 🙂
I think of the 6 you posted, “Cows-sunrise-pasture-r-e-2.jpg” is my favorite. Here are a few reasons why . . .
It seems to be the simplest of the cow pasture shots. The first cow pasture shot has the dark top of the post very close, which is usually a great thing to do, but because it’s larger than the other dark subjects of your photo (the cows), then it draws attention away from them. Your second shot doesn’t have this distraction. Secondly, the second shot has a very clear focal point: the sun with the sun rays. While it may not be considered the “subject” of the photo, it’s the object with the greatest visual mass, so my eye goes there first. My eye then travels over the rest of the photo to get the context and read the story of the photo, but then gravitates automatically back to the sun . . . and then around again. It keeps the eye in the photo.
In the first shot, the dark tree that the clouds are pointing to catches my attention first. Then the big cow on the right. While it’s a nice scene, and fine subjects, they aren’t as interesting I don’t think as the sunburst and the “feeling” of a farm as hierarchically prioritized in the second shot.
The third shot is of a gorgeous sunset, for sure, but it feels a bit over saturated with unnatural gradations making it look like just “another sunset”. Without any foreground anchors, it’s hard to feel transported into the scene. Visible clues of artificial background darkening also make it hard to enjoy it as a photo of nature.
Those are my thoughts on the cow pasture photos. 🙂 Of course, removing the leaves on the left in that second photo should be very easy. And it appears there’s something photoshoped there in the sunrays. Not sure, but would keep those rays undisturbed so they look perfectly natural.
So then you have that gorgeous photo of the horses in the green field! Edited well. Great subjects to work with. Keep working the scene. Get some intentional lines or shapes somehow. Work the scene like a puzzle. Only include the elements that tell the story with clarity. Keep it simple.
The trees shot is interesting, but not quite dramatic or symmetrical enough from my perspective. Would like to see more texture in the tree trunks, without them being over-saturated.
And lastly, the railroad is nice. Love being at the low angle like that. I wish I could tell that the tracks were bending more. They point to the very center of the image, balancing out the image so well that it feels static. I’d keep the convergence of the two rails landing on a third, incorporating more information on one side of the track or the other. Maybe the rocks on the left have some more interesting shape/texture than is visible right now? Also, be careful taking pictures of train tracks. It’s private property, so the only legal place to shoot them really is from a crosswalk or road, which I assume that’s what you’re shooting from.
Hope that helps! Sorry for not replying earlier.
