Film Technical Information



I have been putting the Contax T3 through its paces with Velvia for the past 6 months. I now would like to photograph low-lit street scenes and interiors without flash, using high speed transparency film. I would also like maximum grain. So if anyone has any ideas on films, ratings and processing, I would appreciate it.

I would also like to use Agfa's Scala film. I believe there are two ISO options with this film. How can I select one ot the other using the Contax T3 (there doesnt seem to be a manual ISO settings button).

Thank you for any help with the two queries.

Best regards



Hi Greg.

I do not have an answer for the first question. I never shot faster than iso 100, but I will try this in the furure.

For the second question (Contax T3 Iso setting):

The T3 does not have a separate Iso setting. You have to modify the Iso by setting under/overexposure in 1/2 or 1/3 stops. This you can costumize in the costum functions. It saves the information even if you turn the camera off.


Available in UK, and I would assume in other countries are self applied DX labels. Maybe you could label one batch for one ISO, and leave another as the alternate ISO???



Agfa Scala is nominally rated at ISO 200, but it can be used from ISO 100 to ISO 1600. Processing is not done by the universal E-6, so you have to send the films to an authorized lab.


Can anyone help with the issue of slide film development? I am aware of the problems of having colour negative film developed and printed at minilabs, but does the same apply to having slide film developed at minilabs? Is there a difference between having slide film developed at minilabs compared to pro labs. Thanks for any advice.

I would reccommend using anyplace that does not just rely on untrained people to use an automatic process. Pro labs and photo development at decent camera facilities should work a lot better for slides, as little or no lattitude available with them as compared to print film that can be off two or three stops and corrected easily.

The advantage of pro labs is that you are able to by a 50 or 100 film processing rabate "card" making each development much cheaper. Most pro labs have quality checking of the chemicals ensuring a much higher quality aswell as they offer push/pull processing at resonable terms. Having paper copies of pictures from slides is always a bit more expensive than from negatives but with newer digital technique you can scan your slides, work on them in photoshop and give your prolab a cd with the pictures on. They can make real prints on silver based photo papers from the digital file - it actually looks very nice - and there is great advantage of being able to consult the professionals at the lab



I have found the mini-labs dirty! That is miniscule foreign matter only visible on big enlargements or projection, as well as drum scanning. I suspect they "stretch" their chemicals and certainly do not wash completely.

Using a pro-lab for both has eradicated the problem and the price difference is not significant. In fact that is what one is paying for.
