Here is my own analysis of my photos above. This is starting to be more a topic of a photo group discussions. I just wanted to know what the post processing people like you think about the photos. It looks like in both photo-pairs the "bad" photo (3893 and 3922) is overburned. The blue flowers (3893) and the sky (3922) shows white which cannot be fixed. In addition to overburning, the photo 3922 shows some kind of intensity curving. I.e., take the better photo 3923 and try modify it to look like the bad photo 3922 with the curves tool. The curve I had to use was of the damaging type -- overcurving. White-point problem? I don't know how to correctly change the white sky in 3922 to the blue sky like in 3923. The manual mode seems to not be manual at all: In photoing a new tree scene in two parts with the parameters fixed, the photos were exposed differently. The common area in two photos is not the same. It is just like the pair 3922/3923: with overburning. The camera does something automatic in the manual mode. While the exposure setting can be locked for multiple photos and that would have solved the problem, not always I have a blue sky available for reference! The camera should expose all parameters to user, or have a possibility to use existing photo as a reference, or have a preset system for exposure. I hope camera manufacturers start increasing the number of bits in the pixels so that camera could take and view good photos without overburning. They are now marketing more pixels instead of improving the photo quality (lens + exposure). At least people can see the poor photos with a good resolution. Overcurving is mystery to me: the photo 3923 modified with a mild curve looks better than 3922.
