if you spent less time worrying about one guy on the internet telling you how you can override the mfg's directions (which they literally spent decades and billions of dollars on developing) and more time on what mattered you could actually get some half decent shots once in a while

I was cleaning out some old text files and found a two-year-and-change old draft response in this thread. It was a lot of effort at the time (slow work day) and I thought some of you might like the end result, so I wrapped it up and present it here:

unpacked robinhood posted:

Did anyone ever try to compare film quality through the ages ? Say early popular mf stock compared to present ones.

I'm thinking mostly in terms of achievable resolution if that makes sense.

Twenties Superstar posted:

spatial resolution would be a function of a films granularity and the developer/process used. probably the finest grain you could go would be something like kodak tech pan with the appropriate developer. looking back i would imagine ancient film stock wasnt all that sharp as i suspect they would have improved with technology (maybe plates were sharp as hell? i dont know but i doubt it). with things like tech pan mostly retired at this point perhaps we are over the hump of extremely fine grained film stock and we'll just have to settle for tmax 100 for the rest of time :)

Most plate processes are really fine-grained if you nail the execution. At the very highest extreme, daguerreotypes are far beyond "sharp as hell", but have an ISO of about .05-.25 depending on your exact preparation.

Panatomic-X was finer-grained than Tech Pan, but also even more toxic than most to manufacture, due to cadmium content.

Here are some approximations I was able to dig up, based on 30% contrast (which seems standard? - everyone uses it or something close). Most of these numbers are from the American Institute for Conservation or from published Zeiss test data; I've cited the numbers where appropriate. Interestingly, Zeiss reports wildly higher numbers for certain films. I think this is methodological; Zeiss obtained their data from inspection by microscope, while most others report from scans. It seems like some films just scan (relatively) poorly. Films where this is especially prominent I've called out with an asterisk.

You're not giving up a lot of sharpness with TMax 100. I'm fond of Panatomic-X for that application, but it's about the tonal response more than the "fine grain at any cost".

Adox CMS 20: ~275 lp/mm (Zeiss) (the manufacturer claims 800 lpm, but everyone else says going over 300 is a fairy tale)
Fuji Acros: ~160 lp/mm (Zeiss), 200 lp/mm (Fuji)
Kodak Panatomic-X: ~170 lp/mm (AIC)
* Velvia 50: 160 lp/mm (Zeiss), 100 lp/mm (AIC)
Kodak TMax 100: ~150 lp/mm (AIC), ~180 lp/mm (Zeiss), 200 lp/mm (Kodak)
Kodak Tech Pan: ~142 lp/mm (AIC), ~140 lp/mm (Zeiss)
Ilford Delta 100: ~140 lp/mm (Zeiss)
Portra 160NC: ~100 lp/mm (AIC)
Ektachrome G/GX: ~80 lp/mm (AIC)
Fuji Velvia 100: ~80 lp/mm (AIC)

By comparison:
Kodak Tri-X (2004 revision - original version would be a bit less): ~65 lp/mm (AIC), 85 lp/mm (Zeiss), 100 lp/mm (Kodak)

Incidentally, Durst claimed that just about everything over 130 lp/mm is unlikely to show up in a darkroom print, and the AIC indicates that most production camera lenses are unlikely to record much over 140 lp/mm in any case (this data is old and is probably broken by the new super-sharp lenses like the Otus and Sigma ART series). Something had to record their 170 lp/mm on Panatomic-X, though, so...

For CMS-20 it is an inverse number, like f-stops. Big big number, small small fun, no payoff in the end.

I hardly ever develop and scan my own color film anymore, but have had some pretty variable results from different labs in my area. Predictably, the places that are closest to where I live produce the scans with flatter colors and/or digital artifacts in the grain:





...while the farther-away place gives me the good* stuff:

I know they're ergonomically obtuse, but are they badly unreliable? Seems like a lot of the lenses are pretty good.

I have an Exakta VX1000. Mine is not in the best condition but it's a beautiful piece of kit. They were kind of the SLR version of Leicas in the day, expensive and high quality but somewhat feature poor. They were not cheap when they were new, but they are cheap now because it's hard to keep them in working condition. They are super complex mechanically and are subsequently much harder to service than the usual mid-60s photo gear.

I dunno how much film you shoot or how much scanning costs at your lab, but even at my relatively cheap lab, a scanner would pay for itself after 19 rolls.

I bought a V550 and wouldn't give it up. I think it's just too impractical to have anyone else do your scanning. They'll gently caress it up and there is so much to gently caress up that you'll have a nightmare going back and forth.

"You better not buy me that goddamn tourist av"

A friend of mine sent me his old Canon 1n with battery grip because it was just collecting dust for him (he's had a photo business for decades). I decided to christen it with trying some new rolls of film that I haven't used before. So the question is...do I shoot the roll of Ilford Delta 100, or the Ektar 100 first?

I have a v600 but I’ll assume it’s the same software. After installing the Creator’s Update i could only run one scan before the program crashed. After trying a few solutions I started running the scan software in admin mode and it’s worked fine since.

I have a v550 and Windows 10 and it works just fine. There was a bug in Windows that prevented Epson Scan from working properly for a bit but that was fixed months ago.

I can also confirm that the v550 is working fine with Windows 10 for me. In fact, I'm typing this while waiting for a scan to finish. I would say, just download the software and drivers from the Epson website rather than the included disk just to make sure you've got all of the up-to-date versions.

Use a virtual machine with whichever OS you want and use silverfast.

When it’s OS reinstall time you won’t have to reset it again and you never have to worry about compatability.

I've had a lot of problems running Epson scan on windows 10, i had to run all sorts of compatibility modes to get it to function, but it's very jerryrigged now and it might end up crashing again.

Epson Scan was working fine for my V600 but I moved to Silverfast and it's also running fine. My main issue now is that Adobe products won't install on my machine, failing with a P44 error. I'm using a portable installation now that's probably bitcoin mining malware to boot.

Send him an email with your scans and let him know. He'll fix it but you'll still end up eating a shipping cost. He might have a solution that doesn't involve sending it to him.

I got a Spotmatic back from him a few weeks and while he fixed the capping shutter and replaced the seals, he didn't clean out the viewfinder and mirror and either didn't replace the meter cell he charged me for or didn't re-calibrate the meter after replacing it. Given you have to take the prism apart to replace meter cells you'd think he'd have cleaned it while it was supposedly open. I never actually use the meter in my Spotmatics so I'm not going to spend the beaucoup loonies to send a brick of a camera back to him from Canada.

Figured I'd give an update on my shutter issues given that, WTH, it might help someone else.

Eric, who's a nigh-mythical figure in Pentax circles, does seem to have fixed my MX's shutter problem issues after giving it another go-around on his bench.

He did blame a "ding" in the camera as a possible source of the problem, though it was there the first time I sent it to him. I've babied the drat thing ever since I got it.

In summary: it's all good, but I'll probably try someone else next time I need a CLA.

Mostly price (a roll of Portra is ~$18 here, and another ~$25 to develop and scan) but I also find it interesting, I love film for the alchemy aspect of it and like to fiddle with things. If I could have found a bulk roll of normal still colour film I would have bought that instead but that doesn't seem to be a thing that is produced anymore.

I haven't noticed any super strong colour shifts in the example pictures I've seen online from people developing in C-41, obviously if you're shooting tungsten balanced film in daylight everything will be blue... I've seen varying degrees of praise and condemnation for using cine film but I've liked the example images I've seen in most cases so eh? Worth a shot. I'll be sure to tell any tales of misery I have in here for laughs if/when they happen.
