Yes, I do that quite often with my eyes, Andre, and it is quite natural that the DoF changes. But the most remarkable thing is that even the blurry regions out of the DoF do not appear as blurry if one doesn't consciously perceive them due to "brain activity that cheats our perception". You really have to consciously notice the blurriness.
It ios interesting to see that the harware (iris, lens, retina) react quite like a camera lens, but the software (mind/perception) are able to do something unexpectable with the delievered optical data.

Hi Nick,
I think this is a good example of how the photo lens can do a pretty good job of duplicating what is seen by the human eye.
Try it yourself. With the bare eye try focusing on something about 1/2 meter in front of you and you will notice there is a blurred foreground and background in your own field of vision. I think that is one of the reasons why images like this one have a general appeal. They are naturally agreeable to the human senses.

Thank you very much, Andre! I didn't consider it this way regarding the plant. I thought that the part that is out of focus would be rather a disadvantage, but I have to reconsider it keeping in mind your comment.
Have a nice day,
Nick

Hi Nick,
I think one of the good things about this image is the slight out of focus foreground. You seem to have a good amount of the plant in focus to show of the very natural texture. The image is also better for the plant not being perfect. The aging spots and leaves in chaos give the image character.
Good job on this one I think!
Andre
