Isn't Delta 100 pretty contrasty to begin with? Also with ilfosol isn't it just an agitation once every minute for 10 seconds or so?

How do yours compare here: https://www.flickr.com/search/?text=%22delta%20100%22%20pushed&view_all=1

There are a few photos there that look like mine, but most have a far more reasonable level of contrast. All of my of my photos look like they were made with a deep red filter on the lens.

Does that "once every minute for 10 seconds" agitation scheme apply to tray-developing or just tank? From what I've read the "once through the stack every 30 seconds" is the "best" method for developing in trays, regardless of developer. But since this was my first time using trays for film, there is a 100% chance of there being gaps in my knowledge and technique.

If Delta 100 is just naturally super-duper-contrasty, then I may need to find something else. It's too bad they don't make Pan F Plus in LF. I love that stuff. :(

Not at all the same, but low-sensitivity stuff certainly exists. You could also try orthochromatic/technical film.

Pan F Plus is exactly what I think of when I think of naturally super duper contrasty film. If you want less contrast, how about Acros?

I've actually tried ortho film (well, paper) before. It's what I was using prior to Delta 100. I liked what it did with foliage, but was not a fan of the way it makes skies into huge patches of empty whiteness.

Perhaps I'm just looking back at my days using Pan F Plus through rose-tinted glasses, but it always seemed pretty perfect to me. I've been shooting digitally the last few years and have only recently gone back to analog, so maybe I've just gotten used to low-contrast RAW files.
Acros is a definite possibility and one that was a contender with Delta 100 when picking a stock to use; the Delta eventually won because of price. If, when I finish off these couple of boxes and learn a bit more, the Delta still isn't to my liking I'll give Acros a shot.

Acros is really cool and worth the price. Zero reciprocity failure to 120 seconds and +1/2 stop out to 1000 seconds means it's actually faster than HP5+ (the other B&W film I use) past 25 seconds :mrgw:

I've also gotten usable images out of negatives that were 7 stops overexposed:

Alright, I think I may have figured out what made my negatives look like photocopies in terms of contrast. All the exposures required lengthened times to correct for reciprocity failure, but I didn't decrease the development time. According to the chart in "Using the View Camera", I should have decreased the development time by close to 20% (assuming the Delta films act like other Ilford films). I didn't know such a correction was needed because back when I shot roll film I never did any kind of special development, so I never really looked into it.

Er no. I mean yes exposing for longer and developing for less time will reduce contrast in midtones but that's not standard practise for just developing something you compensated for recip failure on.

That's what I read elsewhere on the Internet and in "Using the View Camera".

"Reciprocity failure is a slowing of the film's reaction to light - a decrease in the film speed. ... The high values in black and white film are relatively less affected by reciprocity failure, thus the increase in exposure time must be accompanied by a decrease in development time in order to obtain the same level of contrast in the negative." -p. 75

What they are describing is a technique called contraction by the zone system. Exposing longer opens the shadows and developing less reduces the highlight brightness. I assume they are suggesting it because like MBA said night shots are inherently contrasty. It's not a bad practise but it's not absolutely required anytime you run into recip failure.

I'm sorry, but this doesn't really make sense to me. Reciprocity failure correction is the exposure you add to get your baseline exposure back to normal, so if you want to do Zone System-style contraction, you'd need to add additional exposure on top of the reciprocity failure correction and then underdevelop. I've done this by accident...

I don't know, it makes sense to me. Reciprocity failure primarily affects the darker tones in a photograph, so when you add exposure to correct for this failure yes, you are bringing those darker areas back up to normal, but you're also over-exposing your higher values at the same time. So to get those higher values back to where they belong you develop for less time. I checked last night and there's a section in "The Negative" that agrees with my other sources, except Ansel takes it a step further and actually gives extended development recommendations for extremely short exposures as well.

I have been lusting after medium format for a while, but I am mainly a travel photographer and I just can't lug that bigass Pentax in the OP, as awesome as that would be. Any opinions on the Fujifilm GF670? It folds into a pretty compact package. It's expensive, selling for the low $1k on eBay. But it does have aperture priority which maybe in the long run will save me money on film because I won't ruin so much of it. Any similar cameras for less money??

There are quite a few older Fuji 6x4.5 cameras that can be had for very reasonable money. The GS645 folds up real small, the wide doesn't fold but is still small, and they can be had for $200 - $300, they are however manual only. The GA series is newer and has full auto mode, one of the models has a zoom. It's like a 6x4.5 Point and Shoot. The down side to all of these is the smaller 6x4.5 frame size, but hey more shots?

The only other thing that comes to mind is the Mamiya 6. The lens mounts collapses into the body and it has AE and AEL modes. It is sill bigger than the Fuji GF but there are 3 lens. You can find it with the 75mm lens for less than the FUJI GF. Of course it is also older and difficult or impossible to repair depending on what breaks.

I feel like a broken record in here, but the GF670 is an amazing piece of equipment. I've had some amazing pictures from it. The huge negatives print beautifully and the enormous slides look great on the light box (still looking for a good deal on a medium format projector). I have no qualms about recommending it aside from the fact that it eats batteries -- the only advantage my Rolleiflex has over it.

You can usually get a Rolleiflex, Yashica Mat, or other TLR, for rather cheap. They're always 6x6 format, but in size or weight aren't much different from a typical DSLR with a small lens.

I remember seeing a Mamiya C in a store once and thinking that it was absolutely gargantuan compared to a Yashica. But I personally had no other experiences with it, so I could have been misremembering.

They are indeed a beast. Yashicas look compact compared to them, but my mat kept breaking in new and exciting ways, so I decided I wanted to upgrade to something more reliable.

I would rather get something as small and cheaper, but if this is the camera I may eventually end up upgrading to, I might as well get it from the get-go. Seems like a good camera and focal length. I'll do my research and studying so I know exactly what I will be doing once I get it, I do not wanna start by wasting a bunch of film.

I have a half dozen sitting around at home, you'll get one every time you develop a roll. If there's a shop nearby that develops 120, they can probably give you a free one.

Yup, the film comes on a spool. As you shoot it, it winds onto the take up spool. When you're done the original spool will be empty. You send the film in with the take up spool, and move the old spool which becomes the new take up.

You might want to look up a video of loading your camera as it's not quite as straight forward as 35mm (though it's still very easy). There is a specific orientation (because of the paper backing) which might not be obvious, and there is a starting mark for how much to prewind the film.
