Ok so really embarrassed but maybe I loaded my film backwards. Camera is the Hasselblad film Kodak TMAX 100. I was looking at my film after developing it and i saw numbers and the word KODAK on the film. ouch ! So i scanned the film to post here and find out what happend. I think loaded it backwards but I have never done that before and don't know what to expect. All the shots were long exposures some as long as 2 plus minutes. The negative is very thin so under exposed because the paper was in the way maybe ? That is why i have the numbers of each frame exposed unto the film through the paper as well maybe ? What did you think happend ? I am hoping the scan show sup clearly on here.

It looks like you have one of the rolls with problematic backing paper. See this thread (among others): (there was a url link here which no longer exists)

Note the emulsion batches affected, and the email address for arranging for replacement of this and any other films within the problem batches.

No, I don't think you loaded it backwards - had you done that, I doubt you'd get an image even after 2 hours.

I think Matt is correct: you've unfortunately got a roll with the bad backing paper.

Thank you yes the beach is only 15 minutes away. So,I will go back but I still have film from that batch and will wait until the Fuji Acros film comes in before shooting.

It's verboten here but this can be fixed with the help of some 'tools' and 'keyboard strokes'.

You still need to figure out what you did to vastly underexpose the film. things to consider:

metering technique
reciprosity calculation
film rating
developer time/temp/capacity

No you have some of the bad batch of film, Kodak for some reason used a backing paper on some of there 120 roll film that caused a lot of problems, you will not get good images with this film.

Here is a cut and past from another post.

From Kodak:
The following Kodak Professional Film emulsion numbers may exhibit image problems, under some circumstances, only in 120 format roll film:
(Emulsion numbers can be found on the film box, the foil wrapper, and printed on the clear edge of processed film near frame number 11.
Kodak T-Max 400: emulsion 0148 roll 004 through emulsion 0152
Kodak T-Max 100: emulsion 0961 through emulsion 0981
Kodak Tri-X: emulsion 0871 though emulsion 0931
Any film with lower or higher emulsion/roll numbers should be free of any problem.
Please direct additional questions to: profilm@kodakalaris.com

I will bracket heavy next time and try to see what way to go from then on. I am using a ten stop filter and trying to figure out what my exposure would be after using the meter in a 35 mm camera to base from. I have an app that calculates from that base exposure and a 10 stop filter. I will try it but again but tell the app I am using a 12 stop filter and see what I come up with. Also while I am thinking about it I might try to search for the guide that Lee filters sends with their ND filters. If I can find it I will try that to. Fun :smile:

Once you meter over 15 seconds just double the exposure to compensate for reciprocity effect, from 1 second to 15 seconds I give 1.5 stops extra exposure, under 1 second expose as metered, you do not need any app for this and they only serve to confuse more than help, is is only grade 3 math to work it out in your head anyway, with a 12 stop filter on ISO100 film you will have rather long exposures.
All films have different reciprocity curves but the above works well for me with most of the film I use, for long exposures I mainly like Kodak Tmax100 and the above curve is based on this film.

Yeah I had 4 boxes of the crap I got from BH , I got it all replaced from Kodak no problem, I still have 3 boxes of the bad stuff that I am going to put into my silver recovery tank when I get around to it, probably a good $30 worth of silver on all that film :smile:

Mark my problem I have just a straight prism not the metered one on my Hasselblad. So I use my 35mm a Nikon f3 to get a base exposure and for example if the F3 is saying 1/60 with no filter i put that in the app and add the filter and it gives me the time to expose. Here is a screen shot from my iphone of the app. You can see that it gives a time of 17 seconds with the 10 stop ND filter. So maybe i need to add the reciprocity factor to that 17 seconds. I will try that. I sure appreciate your help this long exposure stuff is all new to me.

So if my exposure 17 seconds I will double that exposure to 34 seconds. I love testing and shooting and trying new things so this will be right up my geeky alley :smile: I will also bracket a few places under that 34 seconds and see what i get as well.

The best of luck and fun on the re-do! I have loaded my Calumet 6x7 roll film holder for 4x5 backwards once, I am trying to remember if it went on the take up reel backwards -- no mistaking the problem if so!

Sometimes having the numbers can work out. Unfortunately, Alex was only 12 -- would have been perfect if the numbers matched!

This is Tech Pan, long out-dated and not nicely kept for some of that life. Hence the numbers, probably. I just thought Tech Pan and an original Diana camera were just meant to be! After all, the camera and the film might have been made in the same year, give or take a few! Image below from a scanned silver gelatin print (7"x7").

Well if you don't pay attention, like I didn't, you could load the film upside down. Then you would be exposing the backing paper, instead of the film :blink:
I auto loaded the Hasselblad back like I would be loading a TLR. DUH...the light comes from a different direction on the TLR vs. the Hasselblad.

If you tend to photograph long exposures often, consider using Fuji Acros film as it doesn't need any reciprocity corrections. Simplifies things tremendously :wink:
