Ed,
I neglected to ask (or I missed) whether this incredible pano is from stitched frames, or is cropped from one frame?
I assume that you went to a higher ISO and a higher shutter speed due to the fact that you were shooting with a telephoto, and wanted to be sure it was steady? Sensor+ allowed you to achieve a low-noise ISO 400, but it effectively reduced your sensor to 15MP from 60, correct?
Do you feel that you miss any shooting opportunities due to long exposure limitations of the P65+, as compared to the P45+, or that the Sensor+ feature compensates?
Again, an incredible shot. I'm trying to understand some of the considerations that allowed you to achieve it! Thanks.[/QUOTE]
The large pano is a stitch of six sensor+ exposures. As processed it is some 20k pixels wide (note the 100% crop sampling).
You are correct, Sensor+ does cut the resolution of each exposure from from 60MP to 15MP. That said, my experience confirms Phase One's claim that the Sensor+ image is sharper and smoother than you would see from a 15MP bayer sensor. This is due to some internal sensor magic I don't understand. It appears as though the 15MP is antialiased from the full resolution much the same way you would see when downsizing an image using Bicubic Sharper in photoshop.
Furthermore, I have found that capture one does an excellent job of scaling images up to 200%. Visually it seems better than upsizing in photoshop. Anything requiring over 200% I use Perfect Resize from OnOne. Doesn't replace the resolution lost with Sensor+ but produces acceptable results in most circumstances.
You are also right about the long lens, I wanted to stay at or above 1/100 on the shutter speed to avoid long lens shake.
Finally, I almost never shoot exposures longer than 30 seconds. When I upgraded to the P65 I went through six months of images and had 1 or 2 that we over a minute. If I wanted to shoot star trails or something similar I decided my Nikon would be ok for that job.
WOW! :thumbs:Alpa TC + Hasselblad 60 meg and new firmware + 36mm Schneider APO
Sergei, I love it. Is that an F3F? Where?RZ ProIID + Mamiya ZD + 50mm (or was it 110? i cant remember, sorry), C1 conversion
Shot at street level - actually about knee high. Pointed up to get the top of the flag pole. Verticals converged wildly. Used perspective tool in LR to correct perspective - it looked best actually slightly under corrected. Extreme perspective corrections in post usually don't work out well, because the pixels on the flag end of this image are effectively being uprezed (and the ones at the bottom of the image downrezed) and the geometry starts getting weird. Starting with 60 megs of file really helps on the uprez issue (but I wouldn't print this larger than 20 inches or so on the long dimension) and in this case you don't have any cues as to what the flag should look like so you don't notice the geometry. The shoot included the ball on the top of the flagpole which came out way too large and elongated - I cropped it out.so woody, how did you adjust perspective...in PS? looks like you shot form the street level, i see no sign of camera tilt, can't imagine that 36mm would see that high, the TC does not have shifts...
thanks - the platinum print is an image from the Gobi Desert taken by my friend Lois Connor. She makes her own paper and shoots 7x16 film in a camera that she had made. She's now scanning and printing digitally, large.Nice book collection, and nice platinum on the wall
Marc - thanks. I made this to show myself that it can be done - I've been exploring the limits of the TC and the 12 Max. It's great having both. The Max is the real deal as a technical camera - assuming that you focus stack rather than tilt - it's the most really satisfying digital tech camera that I've seen or used. And for a mere $2k more you get the TC, which with the 36 is the Hasselblad Superwide C, but digital. Another dream come true.WOW! :thumbs:
Using the Image Bank Woody?

Terrific lens, but the 60 meg back pushes it to its limit - slightly noticable at the edge unshifted, noticeable more shifted (I also have the Alpa max). I'm spending some time with it sorting out the real limits on shifting. Appears to be about 10mm with this lens. When shifting more with this lens (around 12 or 13) the H back starts to have an issue with centerfolding (probably caused by the very acute angle that the light is striking the back at) but 10mm is the limit on the good part of the image circle anyway. I hadn't commented on the centerfolding earlier because until recently I was using beta firmware.That 36mm looks very nice. Just keep teasing me Woody. LOL
Terry - It's the Alpa exclusive.Woody -
Is that 36mm the one listed as Alpa exclusive on their site (similar to 35 with different filter size) or a new lens design?
What do you have besides the 36? I have the 47 and the 4.5/90 digitar (I'm in NYC also if you want to give them a try).My next problem with this is deciding on a third lens to use with my Max. I don't want to go beyond 3 - I'd like to keep this kit fairly compact. I'm thinking of the 120 Schneider on the Alpa list but I'm having second thoughts.
