The other day, I had a stock developer solution go bad. After I mixed up a new batch, I took a quick picture as a test, using a 10" lens, of a house across the street. Here's the photo:
The image was shot at f/11, and I focused on the house number. The camera, a Toyo AX, was leveled by eye, as I didn't have a small level handy. About 1" of front rise was used. Other movements were at their home positions. The lens is listed as covering 5x7".

To me your new developing solution is out of focus or you have a lens/camera problem.
With the calculator in hand, the roof has to be sharp.
So IMHO there are only two possibilities:
a) Front and rear standards are missaligned
b) Film was not flat in the holder, we don't see the guide casting a shadow at right side... perhaps the sheet was not well loaded, or the sheet was not flat because of other issues.
A) is possible, but I've used this camera/screen for decades. B) is unlikely. The lack of a full black border on right is due to cropping in scanning software.

Pere, the lens focal length was 10" (~250mm) and the implied format was 5x7.Originally Posted by Pere Casals

Peter, I have no idea why the upper part of the image is out of focus, but a minor point it looks like you're getting some reflection off the edge of the format opening in the camera, as evidenced the slight build-up of density in the lower left corner of the image (likely due to the position of the sun, as it's not apparent in other corners). You may want to "blacken" the format edges.
Oops. Sorry. The format was 4x5. (Toyo AX). The lens is listed as covering 5x7". My question, really, is does this look like a "running out of coverage" issue, or something else?

Peter, on looking closer there does appear to be slight convergence by aiming camera upward, judging by the vertical edge of house on the left, messing up the DOF. Obviously the foreground trees are too close for DOF.
hmmm , yes... in that case calculed dof is only 8m !
given the near focus the roof can be out of DOF
Hi Jerry, That's from not taking the time to mask the negative when making the scan.

Did you look at the actual neg with a loupe? Maybe you have a scanner issue.
