K3-II + DFA 50 + Pixel Shift Resolution

Pixel shift isnít doing the same thing. Pixel shift in the Pentax ecosystem is about increasing bit depth. I have, with a few images, seen an apparent increase in resolution with it, but it is just colour acuity increasing. I believe Olympus uses pixel shift to increase the pixel count of the image rather than increasing the bit depth.

6x7 LS (Leave Shutter) Lens: Use on K-Bajonett

There is no mechanical linkage between the K-mount body and 6x7 lens in the adapter to trip the shutter. The camera simply has no way of affecting the shutter.

There is no shutter release point on either the 90 or 165mm leaf shutter lenses, only the sync terminal.



The 90mm has a cable release socket designed for doing multiple exposures. The op can use it for tripping the shutter

No. There is no mechanical linkage in the 6x7 adapter to allow this. The only way to trip the 90mm LS shutter with a K-mount adapter on it is as I described.
Giving it more thought though, as the lens is able to do multiple exposures, one should be able to make what you want to do work, but for the slight increase in sync speed you will get, just over a stop, it hardly seems worth the effort.

Set the camera to a very slow speed, plug the flash into the lens via the PC connector and use a cable release on the lens to trip the lens shutter while the camera shutter is open.
Note this will only work in a pretty dark environment such as a studio with very dim modeling lights.

My take is the band was none to happy with him for taking this on.

The problem wasn't with the band using his image(s), it was with an outside company lifting them for advertising purposes. This was made very plane in the OP's link.


Sure, how did it work out for the Kamikaze pilots?



Ideally, the photographer should not be airing his dirty laundry in public.

By shaming the band online, the photographer tossed a bomb into their relationship and probably buggered up any possibility of working with anyone in that particular field again. He may have been in the right, but he lost the battle and the war./

A box and cable kit is a single power pack with several heads attached to it by electrical cables. My light kit is an older Photogenic Photomaster 800ws power pack and 4 heads. The pack and heads fit into a well padded midsized Samsonite suitcase. The advantage of this type of kit is size and weight. The disadvantage is lack of redundancy. One needs to have more than one power pack in case of failure.
The advantage of monolights is that if one power pack blows up you only lose that head.

Actually, the F mount us about the same age as the M42 mount. It's probably 15 years older than the K mount.

Pentax Bellows and Slide Duplicator What am I doing wrong?
Posted By Wheatfield

If you look at a mounted slide, there is almost always fairly significant curl towards the emulsion side. The trick is to face emulsion to emulsion, or in this case to the sensor, and use a lens with some field curvature. The curvature will never match perfectly, but it will be an improvement over a flat field lens. If you have your slides in glass mounts, or if the slides have little curl, then a flat field lens is called for.
I find stopping down to at least F/8 gives best results.
Some lenses just give really bad results when used as close focus lenses. I’m not sure if this is part of the problem the OP is having.
I’ve been digitizing some of my old negs and slides of late. I’ve been using enlarger lenses for the optic on the bellows. They are flat field, so have to be stopped down a lot if the slides are curved, but I have better enlarger lenses than camera lenses in the required focal lengths that will fit the equipment. Also the neg holder seems to keep things flatter than slide mounts flatten transparency film.

I expect that as long as one is using AA batteries to power the units the odds of overheating are pretty slim. In your link, the guy is using a Quantum pack. I recall they shunt enough juice into the flash to give virtually instant recycle times.
For a while my Metz 60 CT2 did double duty as my studio flash. I bought a twin head and ran both off the same power pack. It worked well enough but it was slow, something like 4 seconds to cycle. It ran slow enough that nothing ever got all that warm.
But yes, start pushing the recycle times with a steroid monster power pack and the life of the equipment will probably be quite short.

I can't recommend anything in particular regarding studio lights, I haven't looked at lighting equipment for so long I have no idea what is good or bad now. I prefer box and cable to monolights, they take up less storage space and are easier to carry./
I do think though, that if you are planning on pursuing a hobby that involves having a home studio, that a plug in lighting kit will be a good investment in your hobby. When I was going through my various phases of photography I started with hot lights (blue floods in reflectors on cheap stands), moved from there to battery powered flash units and cheap umbrellas, and finally I wised up and bought a set of lights. Note that during this period I was not making money with my cameras, or at least not in any great amount, I just kept finding that applying the wrong equipment to what I was doing was very frustrating.

I don't think your flash equipment is sufficient. Your battery powered flash units are at best back ups to the back ups that you should have.
When I was shooting schools, I had two complete light sets with me, I was using box and cable sets, not monolights, and my kit was 2 power packs, 6 heads (two were back ups, 4 were used), and I always had an extra light stand. Ditch the zooms and go with a couple of different primes. Your back up camera should be as close to identical as your front line one, different formats is a bad idea. A normal lens for groups and a short tele for individual or a couple of people is all that is needed, but back up lenses are a good idea. Another K1 and even a kit zoom should be on your shopping list, along with at least a full light kit that can plug into a wall.

I dunno, it might have been fun. You never know who you will meet at these things. As for being a dream job, meh. As a former male porn star, I know what dream jobs are about, and photographing people at a party is well down the list compared to some of the jobs I had.
