Thanks Doug!I have no experience with the 28. However the Schneider 47 and Rodenstock 40 require very little correction in my experience until relatively strong movements are placed on it. YMMV

TimMy long awaited trade in has finally happened and so in one fell swoop I have a whole new setup. First impressions are great - love the files, especially the Sensor Plus ones though I am slightly surprised by dark mid-tone and light shadow noise levels at ISO 100 (C1 current version, naturally).
The larger sensor shows up the weakness of my glass immediately - even the amazing 80D has slightly soggy corners wide open, the Mammy 28 needs to be stopped to F16 before it behaves anything like acceptably and the Hartblei, well, it continues to amaze but it has now met its match!
I'm really keen to hear any tips'n'tricks people might have. I have the latest FW so can set Custom Functions from the body, which is neat, but am sure there are a host of other useful things I could know...
Thanks in advance for any ideas!

Jack,Ah, tech camera -- let me guess, you left shutter latency at zero? It is a known issue that if you use zero latency on a tech cam with the P40+/65+, noise increases. And the longer the back is left in that state, the worse the noise (heat) gets -- I suspect that's probably your issue. Set long latency and use the trigger cable you had for the P45+.
If that's not it, then something is definitely wrong. I run NR for ISO's 50 and 100 at 15/30/0 and get no noise at all. Try shooting a file using your DF body and the zoom or 80 at f11, both ISO 50 and 100, process using my NR settings above and report back.
Sorry Guy, but this time you are wrong (rare! ) The contax lenses serve me well, but some are just "ok". That's where the Phamyia started (hardly 'junk", but are getting better with each release, and withe Schneider designs are likely to be really great.Not me. I'm pretty happy with the junk lenses.
actually, WB is a piece of cake --- it's getting the color right that is a bitchWhite balance is a real bitch with 1-pixel sensors. On the other hand, there is no noise
True.- any luminance boost (either way with curves, levels, exposure, vignetting tool or LCC based light falloff) will push the noise level by the respective value.
This depends on what you want. I would think the freedom large format gives to create more diverse looks should be one of the advantages. It is just that is is rather easy to wield this freedom to push the camera to ridiculous extremes.So there is nothing special with tech/view cameras. But, of course, with large format lenses you always have to correct light falloff (even with center filter, but the correction is much less with CF)
- technically multi exposure is the best way to go
- if multi exposure is not possible (due to moving objects in the scene) a CF will do fine... but:
- the drawback with a CF is that the GG will be darker. But you could mount it first after the composition is adjusted. So this is minor.
Interesting. A neutral non-polarizing filter (CF or not) is not supposed to change the color cast at all. Do you have any examples of that?Much more important is that a CF introduces lens cast. What is called "lens cast" in Capture One is actually sensor cast and goes from magenta to cyan. A CF may really introduce "lens cast" and this one goes from blue to yellow. And if it is strong there is literally no way to correct it (the blue shift possibly yes, but the yellow shift most likely not).
This goes for the Kodak sensor based P45 but I know that the same "lens cast" occurs with a Dalsa sensor based Sinar EV75 DB. So I'd guess it's the same with the P65+.
I think this is just because the P65+ is pretty huge compared to everything else out there ;-) So the edges on the P65+ is much more challenging for the lens.... but finally I'd also say the image is simply not sharp (at least not in the crop posted). So either the image is defocused or the lens is not accurate calibrated or the P65+ is much less forgiving at the edges than a P45.
I agree!If you are doing large format I think it kind of follows that you are willing to be meticulous.
see attachments.Interesting. A neutral non-polarizing filter (CF or not) is not supposed to change the color cast at all. Do you have any examples of that?
Sorry, but I think Tim brought this on himself: posting an image in challenging light conditions using a large format camera he should expect nothing lessTim, getting all this? :ROTFL:
Talk about highjacking a thread!
No doubt sounded easy, only if I can get a hold of and play with the P65+. BUT unfortunately, like you, you cannot geta hold of an arTec to fondle with, I cannot get a hold of P65+ to do likewise (or at least loaning it out from the only ONE retailer/supplier here).I could show it I guess, but frankly not very interested -- easy enough for anybody to do themselves. I think the important factor is there is not that problem with the P65+ on a tech camera if you use the normal latency setting.
