its always more obvious at the lighter area, example the sky.
this is develop using DDX 1+4.
 
I've never used this film, but I'd bet on developing problems. This would include old developer, wrong agitation scheme, developer temperature (high) and not seeing the negative also incomplete fixing.
 
The left lower-end suggest light-leakage or insufficient fix(?).

You need to provide more information, as well as developer and procedure, as well as the complete negative.
 
Ilford Pan F reportedly has a short latency period, meaning you should process the film soon after exposure. Ilford even makes mention of this on their website. Some folks say you should develop the film within 15 days of exposure.

I've processed mine a full year after shooting and the stuff still looks fine. Maybe there are changes to the emulsion. Just didn't think it looked any different. I did store the exposed film in my refrigerator

I didn't check Ilford pan 50 on their site, but I did develop today Ilford's SFX and this is one of the post exposure notes:

Once exposed, process SFX 200 as soon as practical.
Images on exposed but unprocessed film will not
degrade for up to several months when stored as
recommended.

So this, as above's comment is important; especially if you live in a warm humid climate. Thanks for the post stompyq.
 
i process this after maybe about a week after exposed
no prewash
using DDX 1+4 developer with 4 initial agitation and 4 every min.
soup it for 8mins.

i was also suspecting that either the developer or fixer is exhausted or expired.
is there any way to test the strength of the developer or fixer before using it?

i will probably try again with a fresh batch of developer and fixer.
 
Ilford rapid fix suggests calculating the clearing time and using double that to fix. When the clearing time doubles from what it was when fresh (or i assume is over 2:30, so fix time over recommended 5min), it's time to use new fixer. To find the clearing time, take the leader and put a drop of fixer on the emulsion and let it sit for a bit until that bit seems clear. Then put the leader in the fixer and see how long it takes until you can't tell the transition between where you put the drop and the rest of the leader. The time for that to happen is the clearing time.

If you are using ilford's rapid fixer, make sure you read the datasheet in case I've misremembered.
 
I use Pan F for my Minox IIIs, slitting two 9.2mm strips from 35mm bulk and developing in HC110 at 1:60 as a one shot. I haven't noticed any mottle or uneven developing. Mine expired in 2011 and does seem to have lost some speed. I expose at ISO 25. I use it because it is what I have on hand for slow film and I can expose with the fixed f3.5 aperture of the Minox in the brightest light. Bit of difficulty indoors or outside at dusk though.
 
Lovely Helen - you must have a steady hand for such a low ISO!

hah Charles... a touch of luck, determination, and the excitement of using my friends 1.0 noctilux

for the restaurant shots I have my elbows planted firmly to the table
the others , be very still, hold my breathe and click... Thanks much!!
