fattening up 500t or 200t?

[mattias]

no, the other way around. all stocks show very similar behaviour and it's only when you compare them side by side that you can draw any conclusions. the telecine also has a gamma and response curve of its own, as does the conversion to a still image, the jpeg compression as well as your screen.

...Mattias, your criticism of the example posted is fair and interesting, though a bit abrupt in tone. A more scientific approach would require controlling for telecine perhaps. I didn't see the poster making in claims to being scientific. There are a lot of readers of this board that have never used super 8 color negatives and I think they will be interested to see that overexposing by three stops still yeilds a great image. That is why I think the post is not "useless".

well it started without any tone at all, until somebody called me knäppgök which of course hardened my tone. not because i take offense but because it questioned the credibility of my statement.

(knäppgök means lunatic in swedish)

btw the problem with this board is that many threads start out interesting but get taken over by people who haven't even shot negative before. i've nothing against beginners nor their questions, concerns and discussions and i'm always willing to help, but these matters deserve their own threads. surely we must be able to discuss things on different levels?

Matt is right, if people use these as examples of how film will react they are going to be very surprised when they get their results. I think it's very misleading. There is no control in the example (as steve said).

i seem to recall that you recommended folks to use 35mm slr cams to verify neg film and its different setting and options. cheap n quick results although film material may not be totally identical?

anyway - i think it may be a good option to evalute effects of different settings - especially if a film capable scanner is avail to examine the neg properly. use a motion film equivalent of 1/50th or so shutter speed using a tripod? 200 speed 35mm kodak neg films should be easily avail?

UPD: ofcourse grain is more visual and easier to determine changes/effects on in S8 but for exposure related details 35mm should be a good option.

what say?

indeed. the still emulsions react about the same way when it comes to grain and contrast and as long as you pick the same brand and the same asa you'll get close enough results. and if you're in los angeles you can buy mp stock in still rolls from some labs, i've heard (david mullen's my source and he's usually reliable). i haven't heard about this service anywhere else though. not very hard to load it yourself if you find a short end but you need to find a lab that will process as small lengths as two feet. if you bring it to a stills lab the rem-jet will most likely kill their machine.

there is a company in the US that sells both Kodak and Fuji motion film stock in 35mm slr carts for evaluation. they also supplies the full range motion film stocks ofcourse.

i once posted a link here but cant find it right now.

16mm.com n 35mm com or something like that i believe.

rgb color lab used to provide this service. although, i am under the impression they do not anymore. in fact, their website is down. maybe they closed.

RGB Color Lab has been out of business at least a year.

Here is a post from David Mullen, ASC, from the Cinematography.com forum, discussing latitude, exposure, and an acceptable image:

The confusion comes from the way we throw the word "latitude" around. The film records a range of exposures, at least 12-stops worth. But "latitude" actually means "ability to correct for mis-exposure while still getting acceptable results." Trouble is, we all define "acceptable" individually -- it's a subjective concept.

You can underexpose an image three stops and print it back to normal, but personally, I wouldn't call it acceptable looking. You'd have milky blacks, more grain, a loss of shadow detail. Three stops overexposure and printing down would be a little better-looking, but you'd have muddy whites and bright highlights that look soft, lacking detail. So from my standpoint, I think you only really have one stop under and two stops over to misexpose a shot -- three-stops total "latitude" -- before it's time to consider reshooting. But that's just me.

The other issue is CONSISTENCY. Even if you can correct various shots by printing them up or down, their black levels, grain levels, etc. would change so there would still be matching problems, hence why exposing consistently no matter what general density level you like the best, matters.

You can certainly "roll your own" 35mm motion picture stocks into 35mm cassettes, using a Watson or similar daylight spooler.

However, most motion picture labs running the ECN-2 process are hesitant to offer processing of the short lengths from still cameras, for fear of the splices breaking in the process, ruining other customer's work. If they are willing to offer the service, it is often at a premium, since they need to run the film as a separate run to reduce the risk to feature film production footage.

NEVER process films intended for the ECN-2 process in a consumer processing machine for C-41 process. The rem-jet on the film will contaminate the machine and all the other work going through it with black carbon rem-jet particles.

Sorry, wrong post, but I created a new thread on this topic with examples.
