Never take for granted what your digital thermometer is telling you..... The last few film developing sessions have been a little frustrating. No matter what film I tried, and developers used, I thought my negs were a little thinner than usual. This used to happen on the odd occasion, but became more regular. Exposure wise, I know I am bang on accurate. So this weekend I noticed that ALL of my 5 rolls that were developed, were thinner than I really like. They are all printable, but not as robust as I normally like them. To that end, I bought a new digital thermometer and I found my original digital thermometer I use was over stating the temperatures by 2 degrees!! That means I'm developing film at 66 deg F!!
As a test, I put the old and new thermometer probes into the hot water kettle while boiling for a test and the old one is consistently showing higher temps than it should. I placed new batteries into the old unit... No change.
So I plan to test in the next week on my film and belive this will cure the thinner negs.
So note to everyone... Never take anything for granted thermometer wise if you are using a digital thermometer. They can and do drift!!!
