It's easier said than done but only hand over the final photos when you're paid.

Kodak Tri-X in Ilfotec DD-X: Agitation Query
Posted By tuco

If you are using Ilford's development time for the film, you agitate per their instructions. The established development time of a film is a function of the agitation profile used. And the same goes with any other developer. Of course two seemingly different agitation profiles could essentially be equivalent and in which case it doesn't matter if the developers behave in a similar matter.

I have a Rolleicord IV, K3D with a Xenar 75/3.5 taking lens. An old camera like that usually needs a CLA and new focus screen that turns yellow and hard to see through with age. The lens has soft corners until you stop it down to f11. It is a PITA to load film in it. Just a data point.

TLRs are a good first medium format camera. I don't know what a Pentax 67 goes for these days. But you can put a waist level finder on it and have lens options. It's not as compact of course but with medium format film cameras, everything is a tradeoff.

Rolleicord IV, 100 Acros

Because Nikon uses more engineered plastic in their cameras. Let's convert 5 grams of mass to weight = 0.049N. Not very much weight difference at all.

Did you really expect people to know why one camera has an insignificant 5 grams of mass more than another? :)

The first one has 3/4 of the image with out of gamut blacks. IMHO, that is just too much and not enough sky for me to ignore that big, black void dominating the scene. And what lines the image has from the bridge takes me no where. In the second one the orange is off and not natural on my monitor.

I should look for a longer focal length for this camera to do people.

A 645 & 67 rangefinder makes for a decent film street camera. I've used a Mamiya 7II for that role and shoot my Fuji 6x9 handhold frequently and use it anywhere I can. I think I post just as many pictures with my medium format gear as those with small format gear. But the larger the format, the sooner you'll reach for a tripod and the less convenient it becomes. I'll shoot my Pentax 67 on the street too ( used with a WLF in lieu of a prism) but I don't reach for it as often as the rangefinders in that regard.

What is your minimum handhold shutter speed for a focal length equivalent to 200mm on a FF with your Z?

Agree. But the bar has been raised. For handhold work where you're keeping the ISO low as possible for the best tonal scale, stabilization is something I'd rather have than not.

Perhaps it is from a perspective photo journalistic style of recording weddings these days. Know doubt you'd have more than one camera on hand for the event. And I see reaching for a fast sports-like camera that has stabilization in the lens or body for capturing those needed candid shots an excellent choice and using the MFD for more formal shots.

shutter mechanism problem on Pentax 6x7 MLU

It could depend on the cost of the repair. But some thoughts to consider. If, say, you repaired the camera, no doubt you'd also ask for a good clean, lube and adjustment to go with that. Now you'd have a camera in known good shape if nothing else breaks in the near future.

Buying a 30+ year old 6x7 generation camera has some uncertainty again too. A 67II would not be as old with a better chance of reliability but cost way more than a 6x7. And a 67 generation somewhere in between. Consider that in cost of the repair.

Some nice street scenes. How is the exposure of your film? I ask because the unexposed areas of the film common to the sprockets is showing other than the film's deepest black. That area is the density of the film's base plus fog and the deepest black the film can produce and well call it zone 0. It's being reproduced around zone 1. You can use that as a guide when adjusting the contrast curve of the scan. And it also can indicate if the scene is under exposed in general.

It looks good. I've shot some 400S and Superpan 200 last summer. I'm still establishing a working development time with one of my developers. I liked the 400S results better than the Superpan 200 so far.

Thanks. I mostly grew up in the Pacific NW but have memories of a couple of other states we lived in. I went to the coast a lot growing up.

If you can get your hands on some Diafine Developer, that wouldn't be a problem. It is a two-bath developer that advertises the same development time for a temperature range of 70-85F (21-29.5C)
