Metered body/non metered body and slight confusion!

[atlcruiser]

Jsut got back from a week in Big Bend National Park.

Brought my M6 with velvia 100 and my M4P with fomapan 100. Generally used a 50/2 'con and a 34/1.4 CV changed between bodies.

I had a handheld meer as well as the M6 meter.

Here is the slight confuson:
I found myself using the M6 to get a meter reading and would set the M4P to match or a stop under/over as I used my keen estiamting eye (read guessed 🙂) as conditions changed.

I shot a LOT of fim. Overall it was very bright out there. Very fast shutter and small apatures.

Once I got all of this developed I noticed almsot all the E6 was well exposed but almost all of the Fomapan was underexposed. Most of it is still fine to use and is within the range that can get good prints out of it so little was lost.

I thought that since shutter is shutter and F stop is F stop over a range the films should have performed about right at the same camera settings.

My first guess is that the Formpan 100 needs some compensation..aout a stop down.

The M6 is newer and i have not shot the Fomapan 100 direct out of it. My next step is to try and replicate the "brightness" one afternoon and shoot the reverse with the Fomapan in the M6 and see what i get.

thoughts?

Did you process your film?

If so, what developer did you use? Is your chemistry fresh?

If not, blame the lab. I sent some T-Max ISO 3200 to a professional lab once... and got back some very weird looking washed out negatives and overexposed prints.

Other than that, I have no idea what to say.

You're right that shutter speed and F stop are constants, of course. Sounds to me like the Fomapan was either underexposed relative to the developing regimen used, or under developed relative to the amount of exposure it got. Same thing.

You need to match the E.I. you use to your processing, which generally means testing to get the combination right. If you don't process yourself, it gets a little trickier, but as long as your lab is consistent, you can experiment until you fight the right E.I. for a given film the way they process.

The M4-P's shutter could be running fast.

In-camera/reflective meters are good for slides because they hone in on the highlights. Negative film often works best when it's overexposed a stop or two compared to slide film. The old rule of "expose for the shadows" makes the negatives "pop" more

Switch films in both cameras and do it again...(not the trip just shooting the two rolls)<<<😀😉🙄😱

i did process all the fomapan myself. Used fresh d-76. I also did some arista 400 at the same time and it came out fine.

I like the shutter idea..it is getting fixed now as I smacked it during the same trip.

once i get it back i want to do a head to head with both bodies.

Fomapan 100 shot at EI 100 looks underexposed in general.
