dusty_p. Posted October 14, 2011 Share Posted October 14, 2011 <p>hi guys, I need to increase the shutter speed in certain situations (I can't use faster lens, or additional lighting, or tripod, etc etc) and the only thing left is shooting the fastest film that my camera will take which happened to be iso 1600. I am interested in your suggestions since I'm trying to minimize grain at those speeds and have decent tonal range etc.... Anyone has experience with the Neopan 1600? Also, should I be looking at iso 1600 films or shoot 400 at iso 1600 and then compensate at processing; and if so, which one tri-x, t-max or the ilfords? I process my 35mm at a lab but I can ask what they use and method of processing. Much thanks in advance.</p> Link to comment Share on other sites More sharing options...
leslie_cheung Posted October 14, 2011 Share Posted October 14, 2011 <p>If you want to minimize grain, pull your film. I recommend delta 3200 @1600 or neopan 1600@ 1200. C41 films have less grain but less tonal range as well, if I remember right. Tho, if you really want to cut the grain, shoot digital...</p> Link to comment Share on other sites More sharing options...
craigd Posted October 14, 2011 Share Posted October 14, 2011 <p>Neopan 1600 is wonderful, but I think it's been discontinued. At this point I agree with Leslie: if you need ISO 1600, use Delta or TMax 3200. Actual ISO for those films is around 1000, so at 1600 you're not really pulling them, just not pushing them as far as you could.</p> Link to comment Share on other sites More sharing options...
lex_jenkins Posted October 14, 2011 Share Posted October 14, 2011 <p>Ilford Delta 3200 at 1600, in a suitable developer, will produce reasonable grain and true shadow detail. I prefer Microphen but I've seen good results from other photographers using Ilford DD-X, Kodak Xtol and other developers. I've also used Diafine with Delta 3200 but it tends to enhance the fluffy popcorn grain of that film.</p> <p>I've also seen excellent results from photographers using T-Max 3200 at 1600. Never got around to trying TMZ myself since I was satisfied with Delta 3200. In the same situation (same theater at night or under stage lights), the TMZ photos taken by an acquaintance had finer grain but less true shadow detail in the darkest zones. My photos with Delta 3200 were noticeably grainier but less contrasty and with closer to true shadow detail. It's a tossup, mostly based on personal aesthetics. I actually preferred the other photogapher's TMZ photos from that same theater, but that's mostly because she's a better photographer.</p> <p>Either way, with Delta 3200 or TMZ, 1600 isn't much of a push, pretty comparable to rating Tri-X at 500-800. But you'll get better results with a developer suited to pushing. I was disappointed with ID-11 and Delta 3200 at 1600.</p> <p>T-Max 400 pushed to 1600 in Microphen will have finer grain than Delta 3200 but not true shadow detail. However it's an appealing look, not too contrasty, and I generally prefer it over pushed Tri-X. Tri-X at 1600 in Diafine or Microphen has also been very satisfactory for me for years.</p> <blockquote> <p>"You might be interested in this thread - <a rel="nofollow" href="00ZFmb?start=20"><strong>Tmax 100 at EI 3200-6400"</strong></a></p> </blockquote> <p>TMX cannot be underexposed that much and produce much of an image other than in the highlight areas. Every time I see claims for pushing a b&w film more than three stops, it turns out the photographer biased the exposure situation - consciously or unconsciously. Every example I've seen to support such claims either showed a photo taken in daylight or the photographer biased the metering and exposure in such a way that the film was not really rated as claimed.</p> <p>The photos taken in daylight - used to support such claims - usually showed good detail and tonality from the lower midtones to highlights, but the background foliage was absolutely black with no discernible detail. In the examples of indoor or low light photos, the photographer would describe a typical EV 4 or 5 lighting scenario but exposure settings that would have underexposed the film only 2 or 3 stops, not the claimed 4 or 5 stops.</p> <p>I'll believe those claims when someone demonstrates it can be done using a control situation and methodology that can be duplicated by other objective persons: standard procedures for lighting, metering, exposure settings, development, etc. </p> Link to comment Share on other sites More sharing options...
mauro_franic Posted October 14, 2011 Share Posted October 14, 2011 <p>Lex, I don't know what to tell you other than that is what TMAX 100 pushed looks like.There is no bias or even relationship to how you under expose the shot, you push 3 stops -> you are looking at film pushed 3 stops.<br> TMAX 100 at EI 3,200 has much smaller grain than TMAX 3200 at EI 3,200. The pushed film has the midtones a lot more compressed though.<br> It seems from your comments that you have pushed TMAX 100 3+ stops and didn't get good results. Please post them - I would like to see them for analysis. Thank you.</p> Link to comment Share on other sites More sharing options...
mauro_franic Posted October 14, 2011 Share Posted October 14, 2011 <p>I can also tell you TMAX 100 pushed looks fantastic on a 4 feet by 7 feet canvas. (Direct observation nose to the print).</p> <p> </p><div></div> Link to comment Share on other sites More sharing options...
mauro_franic Posted October 14, 2011 Share Posted October 14, 2011 <p>When it is not pushed the midtones look buttery like this:<br> http://shutterclick.smugmug.com/Photography/Only-TMAX/15377450_PJTRpm#1150708805_8eSeK-X2-LB</p> Link to comment Share on other sites More sharing options...
Karim Ghantous Posted October 15, 2011 Share Posted October 15, 2011 <p>I await Lex's rebuttal. Pending that, if it weren't for Mauro's efforts, I'd be fooled into thinking that film cannot match a 12Mpx DSLR, let alone a 24Mpx one (and how about the claim that DSLRs out-resolve 6x4.5!). I thought EV -2.0 was impressive - but EV -5? Wow.</p> Link to comment Share on other sites More sharing options...
lex_jenkins Posted October 15, 2011 Share Posted October 15, 2011 <p>Mauro, I've seen your example photos. They're lovely, aesthetically. You're a skilled photographer and could probably wring out detail from negatives in the darkroom or via scanning that would defy the efforts of most amateurs.</p> <p>But as I said before, the only worthwhile test would be to decide up on a methodically sound control situation that can be duplicated by all participants who care to test your assertions. Otherwise we're debating personal aesthetics, and not any sort of methodology.</p> Link to comment Share on other sites More sharing options...

dusty_p. Posted October 16, 2011 Author Share Posted October 16, 2011 <p>the dude at my lab also advised me that I'll be "pushing it" if I push more than 1 stop, which is within film's natural range. Going against that, I just switched the iso to 1600 in camera that was already loaded hp5. Should I tell them to push it 2 stops or more? I am looking for well exposed negatives.</p> Link to comment Share on other sites More sharing options...

sebastianmoran Posted October 16, 2011 Share Posted October 16, 2011 <p>Mauro, thanks for the comparison. This is a perfect demonstration that N+ development affects the highlights and not the shadows. </p> <p>What does it mean to call this "push" processing? I don't know. Seems like N+4 development to me to get the highlights up where you want them. When I learned the zone system, nobody talked about N+ development as increasing the film speed, but rather for contrast management. Mauro, it sounds like that's how you are thinking of it.</p> Link to comment Share on other sites More sharing options...
lex_jenkins Posted October 16, 2011 Share Posted October 16, 2011 <blockquote> <p><a href="../photodb/user?user_id=6780493">Dusty P.</a> , Oct 16, 2011; 12:36 a.m.</p> <p>the dude at my lab also advised me that I'll be "pushing it" if I push more than 1 stop, which is within film's natural range.

If I'm recalling correctly what the former U.S. representative for Ilford wrote on photo.net's b&w forum several years ago, the maximum true speed of Ilford HP5+ was 500, when developed in either Microphen or DD-X. That was based on the standard methodology for determining a film's true speed.</p> <p>However HP5+ pushes fairly well. Ilford offers useful and practical advice on push processing their films. <a href="http://www.ilfordphoto.com/applications/page.asp?n=88&t=Developing+Black+and+white+film"><strong>Push processing documents on Ilford website</strong></a>.</p> <p>I prefer Microphen stock solution for pushing, but there are other suitable developers. HP5+ pushed to 1600 should do well in Microphen stock solution for 10-12 minutes at 68F. See <a href="http://www.ilfordphoto.com/Webfiles/20062102012331472.pdf"><strong>Ilford's PDF on push processing</strong></a> for additional practical advice.</p> <p>In practical applications - mostly of live theater or other available light candids - HP5+ at 1600 in a suitable developer will have some grain noticeable in brighter midtones and highlights, but nothing objectionable.</p> <p>Keep in mind that your results will depend on certain variables. For example, metering in typical low light scenarios can be very tricky. Over the decades I've used many different cameras with built-in meters - SLRs, rangefinders, etc. - as well as handheld incident and spot meters. Knowing how to meter appropriately for low light candids is essential to getting good results.</p> <p>For example, a camera like the Olympus OM-1 or other SLR from that era using averaging metering can be fooled by attempting to meter stage performers against a black or very dark background, or against the opposite - a white or very bright background. If you're not familiar with the quirks of your camera's metering, you may get results that vary wildly from what you might expect.</p> <p>Take a look at <a href="http://www.fredparker.com/ultexp1.htm"><strong>Fred Parker's Ultimate Exposure Computer</strong></a> for guidelines to typical exposure conditions, including those that cover virtually every conceivable available light scenario. When you know the typical indoor home scenario is EV 4-6, and the typical stage lighting is EV 6-9, and how to use that quickly to determine the appropriate shutter speed and aperture, you'll be more confident and get consistently good results and won't be disappointed by a meter that's easily fooled.</p> <p>Typically if I'm photographing people I'll try to get into light comparable to my subjects and meter off the palm of my hand. With live theater performances I can usually check the stage lighting ahead of time. If not, I'll use a spot meter and meter off the subjects or a suitable bright midtone area.</p> Link to comment Share on other sites More sharing options...
lex_jenkins Posted October 16, 2011 Share Posted October 16, 2011 <p>Most of this is a digression unless folks are suggesting the OP use TMX pushed to 3200 for the situation he described, rather than a more suitable faster film and less extreme push.</p> <p>Mauro, have you published your methodology anywhere, either on a photo.net discussion forum or elsewhere online? I'd like to see a description of your methodology so I can try to replicate your process.</p> <blockquote> <p>"There is no bias or even relationship to how you under expose the shot, you push 3 stops..."</p> </blockquote> <p>I may be misinterpreting your statement here. If you're asserting that exposure has no relationship to pushing, then you seem to be describing N+ development to control contrast. For example, if you rate TMX at the ISO of 100, but give it extended development equivalent to three stops, then you're not pushing the film. You're extending development to increase contrast.</p> <p>Again, I may be misinterpreting your statements, but you seem to be deviating from the widely accepted definition of push processing. The widely accepted concept of "push processing" means underexposing the film, followed by a suitable development process to compensate for the underexposure.</p> <blockquote> <p>"...you are looking at film pushed 3 stops."</p> </blockquote> <p>I'm not sure what I'm looking at until I have a better understanding of your methodology.</p> <blockquote> <p><br />"TMAX 100 at EI 3,200 has much smaller grain than TMAX 3200 at EI 3,200. The pushed film has the midtones a lot more compressed though."</p> </blockquote> <p>Frankly, I'd be surprised if there are any midtones at all in TMX underexposed five stops. Perhaps your underexposure is less drastic than five stops. And a good scanner can salvage thin detail that would be impractical with conventional darkroom optical enlargers.</p> <p> </p> Link to comment Share on other sites More sharing options...
mauro_franic Posted October 16, 2011 Share Posted October 16, 2011 <p>Sure.

mauro_franic Posted October 16, 2011 Share Posted October 16, 2011 <p>The shots were taken at 1/125 sec f11 I believe. I metered with a Sekonic 358 excluding the sun and read EV9. I spot metered with a 758 and measured most areas within +3 and -3 of EV9 (excluding specular reflections).</p> Link to comment Share on other sites More sharing options...
mauro_franic Posted October 16, 2011 Share Posted October 16, 2011 <p>It is not surprising to keep midtones when the majority of the scene was contained in 6 stops since Tmax at EI 100 has about 15 stops of DR. In general you give up one stop of DR for every stop you push.</p> <p> </p> Link to comment Share on other sites More sharing options...
mauro_franic Posted October 16, 2011 Share Posted October 16, 2011 <p>This is what the negative would look like in the 6 stops around EV 9 (simplified). Note that even with this amount of pushing, the 6th stop gets very dense but does not reach the full density allowed by the film.</p><div></div> Link to comment Share on other sites More sharing options...
mauro_franic Posted October 16, 2011 Share Posted October 16, 2011 <p>Gradation would be sacrificed though - as you can see. <br> Bright areas would be blown (around the reflections on the rails).</p> Link to comment Share on other sites More sharing options...
