I've had a large number of photos rejected recently for Technical Issues. Some of them I get, others I'm not entirely sure what the issue was. Enclosed is my latest rejection that I'm not sure about so if anyone has any suggestions I'd love the feedback/criticism to improve. Thanks all! (NOTE: I scaled the image down to fit in this post).
Adobe zoom to 100% to 200% to check for technical issues. So please post the actual, original file - shrinking may have hidden the very problem we're loooking for.
The top of the mesh fence has overexposed highlights. The barbed wire is underexposed shadows.
The vertical post is not straight. The tree at the bottom should be cropped out. The focus is not good.
In addition to Ralph's comments, it also seems that you've added a vignette which is not permitted in Adobe Stock.
Need to look at the photo on a larger scale. Is it just me, or is most of the barbed wire blurry?
The barbs near the pole appear to have the sharpest focus and then focus falls off toward the edges of the image, which would seem to indicate that the depth of field is too shallow.
