But first your HTTP client tries to form a fully qualified domain name when you type an incomplete one like pentax.ca by adding http, https, .com, .net, etc.

I don't see how Sony is involved with internet DNS servers redirecting your HTTP requests. But perhaps the site name is now ricoh-imaging.ca or something.

It's all about the size (of the viewfinder)

That's kind of weird to just like looking through a view finder and pushing a shutter button and not care about nothing else of the image. :) You don't even have to meter the scene because you don't care if it's a good exposure or not.

So I can see you wouldn't want a view camera. Those are not fun to carry around, setup and look through the ground glass. A very slow process just for viewing. In medium format a Pentax 67 with a waist level finder (aka folding hood) will give you a bigger view than that Hasselblad. And with the WLF on that P67, it will weigh about the same as that Hasselblad and a more convenient size to carry around.

A rescan of an older picture of a scratch model airplane builder I doing for a xmas gift. I kept tilting the front standard until both the airplane and face were in focus.

Why Medium Format?

MFD has decreased dynamic range and tonal scale the higher your ISO just like small format. A stop better DR or so over small format is not going to salvage the poor tonal scale you get at ISO 18K compared to base ISO. For me, tonal scale is one of the most important attributes of a portrait. YMMV

Sweet, sheet film?

I did a woman's picture like these. I could see from the negative that no way, no how, that she'd ever want anyone to see that. So I never scanned it.

Angenieux enlarger lens : is it worth it?

At 88mm I assumed it was for a medium format enlarger which would cover a medium format camera. As far as adapting for use on a camera all I can say is if that interests you then go for it. But it could easily be one of those things that after you do it, take some sample shots then that's as far as it ever goes. YMMV

In my Jobo C-41 Press Kit instruction sheet, it gives a temperature/time chart for rotary tube processing. Something you can make at home. I have plans to check out the 75F option. But most likely after this holiday season and the start of the new year.

After each wrap of film on the reel, do you check for binding by pushing the film back and forth to feel it tighten/loosen in the reel? If it still moves freely by the last wrap you can have good confidence there will be no problems.

My lightmeter app has a field of view zoom. But it won't go really wide. That's not too much of a problem because it doesn't take a lot of skill to pick out a representative part of a scene.

I'd say you still have to learn to compensate with matrix metering just like an old school light meter. DSLRs have EV comp dials, right. If there are 16 stops of light in a scene and say you can typically only capture 10 stops of detail, the matrix meter should do well at picking out the middle better and not be fooled by the things that fool an old school meter. So you will still lose some shadow and highlight detail. But what if the shadow detail was the most import thing in the scene and you want to expose for that. You'd have to bracket or apply EV compensation and know how much to apply which you'd learn from experience like an old school meter.

Matrix metering of a smart phone is a level of sophistication above a simple light meter, no? I'd think that is one reason.

SMC 90mm f2.8 vs S-M-C 105mm f2.4 lens
Posted By tuco

Views: 463
In other threads I hear talk about how expensive the 105/2.4 is getting. If you're on a budget, perhaps that might be factor but I'm not up-to-date on the availability or expense of the 90/2.8 either.

For the record I have all three: The 105/2.4, 90/2.8 and the 90/2.8 LS. I really don't think about which lens is sharper when I grab for one to use it. And I don't run tests to see which lens is sharper kind of a thing. My observation of the lenses is just through normal use of them. That said I can say, though, the 105mm @ f2.8 yields both pretty sharp results for things in focus for that aperture with decent bokeh especially on non-complex structure.

I'd reach for the 90mm over the 105mm if I needed that focal length range for the shot and wanted the most near-to-far DOF. At f19 the 90mm gives you a little more near ground in focus of course. But if I only could have one lens I would select the 105/2.4.

Some examples but you'd really need to see larger sizes to be more critical of the lenses.

The 90/2.8 stopped down to f16

That's an entertaining description of the P6x7. About every medium format film camera has strong and weak points relative to other medium format film cameras. Two major catagories of MF cameras include studio and field designs. Each can be used in the domain of the other but typically not as conveniently or to the capacity of the other design.

Yeah, they are pretty clean looking scaled down to this size. They were shot at EI 1600 and they are from my 6x9 rangefinder. The larger the negative area the smaller the grain appears to be.

I posted these a while back. This from a 6x17 using Delta 3200. I think the grain looks finer still.

Nice. And, wow, that's a lot hand work someone did.
You don't have to apologize for using a Hasselblad. The characteristic of the image is, to a large degree, the film/developing. The camera body just holds the film.

I've made BW prints from color negatives using special paper for that purpose and found it to be just like making a BW RC print from a BW negative. I think it was Kodak's Panalure paper but I'm not sure.

I downloaded the first one I found that day. I'm looking for a name of the app and all it says is Lightmeter and looks like a brown handhold incident meter with a dial. It has a reflective mode where it takes a picture with the phone's camera for its metering. That works well. I've used it for night, twilight and high contrast scenes and I'm satisfied with the results I get.

I used the app on these fair pictures with Delta 3200 when I forgot to bring my one-degree.

The app meter placed the low values at least a stop lower in value than I would have if I used my one-degree, I'm sure. But I like how it favored the high values keeping the people in the dark and more anonymous
