My office is in the front room of a run-down 12 megapixel sensor but the rent suits me and the landlord doesn't ask many questions.

Interesting. Thanks! I found that -Max also develops rather poorly in diafine.
I guess it's not the best choice for tabular grain films.

It is not. Diafine works best on old tech films. Honestly you don't need tabular grain with it Tri-x (or HP5) @1250 is practically grainless in it.

Been too long since I've posted anything...I've been waking up every weekend around 6 am to walk the neighborhood I grew up in with an idea to document the area (1960s destination subrub, fallen into a sort of poverty), but getting the rolls back I'm just not thrilled with most of them.

A. Depends on how tack sharp you want every iota of your photo.
B. Yes. Dust your negatives you slob.

1/focal length, as usual. Maybe a bit faster to be on the safe side, if possible.

You can probably go a little slower with a TLR since there is no mirror slap.

Oh yeah I forgot you are using a TLR. If you need to, you can probably go 1-2 stops slower than the rule of thumbs then, if you have steady hands or brace yourself well.

Dusting your negatives also means cloning them out manually in LR or Photoshop. Unless you work on a clean room it's almost impossible to get a dust free scan

I love this - I'm surprised you shot it at f/22, is there something funny with hyperfocal distance and MF that doesn't work the same as on 35mm film/digital cameras? I would have thought it's better to shoot at f/16 or something.

The f stop is a ratio of aperture size and focal length. Since MF/LF uses larger equivalent focal lengths, the aperture opening at f22 is going to be a lot larger than that on 35mm, so diffraction will be less. That's my understanding of it.

Correct. There's a reason why there are so many things out there named 'f64'; at large format it's a real thing.

It was 2am, mostly quiet - the large streak through the center is actually a single train. On the right side there's a set of red and white lights, that's an interstate.

Like BANME said it's a different game in LF. I needed f/22 just to get a reasonable amount of the scene in focus. Normally I'd go a bit further (f/29) but reciprocity failure would have made the exposure far too long to be worthwhile.

How do you focus in the dark? Do you just set everything up during the day and then wait for the sun to set? I have trouble focusing my LF camera indoors because it's so dark.

bellows lugosi

I focused on the lights in the distance with a loupe. Generally for night scenes that are so dark I have trouble composing I use a green laser to help outline the frame edges and to focus.

Correct thought process but not reason. F/22 on LF is the same size as f/22 on any other format at the same focal length but larger capture medium means less diffraction limiting of the enlargement. This makes a huge difference when 4x5 is only a 4x enlargement to make an 8x10 print but 35mm is something like 50x.

Which is also why LF makes smoother large prints, and by larger I mean probably bigger than a person, like mural-sized. That said, the high MP sensors do a good job now of enlargements.

I just picked up a Medalist II from KEH that I intend to ship off to Ken Ruth for 120 conversion. My email got this automated response:

quote:

Bald Mountain's shop will be closed until July 1st so Ken can recover his health. (He is expected to make a full recovery!) He will respond to phone calls, emails, and packages then.

Uh, I'd been planning to do this sooner rather than later because this is a Mark Hama type dude who is a wizened octogenarian master at this, but if you want a 120 Medalist conversion you might want to do it like really soon. That's not a promising email in the long term.

For me, Lightroom tends to add a lot of blue/green on film. I have to warm pictures up and move the white balance towards red to not get super dark cold tones everywhere - usually I shoot Portra 160 or Colourmax 200.

I have the opposite problem, same as awkward davies - lots of orange/yellow/red gets added. But I pretty much only shoot ektar.

And how are you getting your negatives into lightroom in the first place? Surely you're doing some of the color first, either through your scanning program or Photoshop. Lots of blue and green just sounds like the curves haven't been touched - red will always be the weakest layer, then green, then blue, purely because of how each layer is laid on the emulsion
