Shooting Kodachrome and Ektachrome to a professional stgandard

[Greg Crawford]

Some of you might now that commercial still photographers test their transparency films (in our case Kodachrome and Ektachrome types) before using them on a paying job.

These test would determine the real film speed, which can very usually less than a half stop from batch to batch. and identify any color drift, that may need to be compensated with color correction filters.

The question is, would it be worth it to you if you could by Kodachrome and Ektachrome film from a single batch no that has been evaluated?

A couple things. You'd probably have to post images on the internet, and you'd probably have to shoot the exact same shot or shots with each new batch of film so that a collective, ongoing inventory could be cross compared.

Also, how do you factor in that different labs may produce a different result?

And what is your proposal?

Thanks for responding Digital Age!

Kodachrome is processed to some of the tightest standards of any film made. Much more so than E-6 films or color neg films.

I have read post where people have had issues with handling dirt and the like with one lab over the other. But Kodak and the other independent lab use the same chemicals for the same temps and duration. They have to. So I am not sure one would have to compare both labs.

Two if you shot a gray card for exposure and a standard color scene with color chart you would have an indication of any color bias and exposure deviation. I don't know of anyone who uses .10 cc color correction filters to adjust color balance in Super 8 Kodachrome, I did this when shooting medium and large format shots commercially

It could be argued that a professional colorist could adjust small color variations even in transparency film.

So what is my point? Just this, I was wondering if it would be a service that super 8 people would be willing to pay for. Or a reason to buy film from one vender over another.

I did not answer your first point, because if I were going to offer these services they would be for a price.
not to just post free results on the web. God, I'm starting to sound like a capitalist, Sorry!

What ya think?
