I am considering purchasing a Alpa 12 SWA for a Phase One 25. And I am being very careful before I buy. I am curious how this combo helps you avoid this kind of retouching. Can you explain your procedure further for my education. Thank you,
-With the 12 SWA I can shift up and, with a digital back, I can shift down (reversing the lens to the back of the camera). This eliminates the need to use the transform tool in Photoshop for correcting perspective.
-With the Digital Non-retrofocal lenses there is no Barrel distortion. This eliminates the need for a special photoshop pluggin to remove the distortion. The pluggins usually work as a batch, but can take 15-60 seconds per image to apply.
-There is no chromatic abberation. This eliminates the extra step in ACR of zooming to both sides of the image at 100% while adjusting the CA tool.
I had shot many small, quick jobs with a D2x, 17-35, 17-55, and 12-24. 35mm digital does not handle highlight blooming as well as MFDB's do. This is very difficult to retouch. My 17-55 lens had CA which was uneven on each side. So I could correct one side or the other, but not both.
So with the Alpa and P45 I have reduced image correction to two issues.
#1- I need to shoot the white plexi and and assign the LCC. This is about as diffucult as shooting a gray card and clicking two bottons in C1 Pro (I shot 15 images yesterday, and it took 5 minutes to do the LCC correction on all 140 captures).
#2 - I also shoot brackets and blend images together much the way many architecture shooters used to use ND grad filters.
It is hard to describe all the ins and outs of using an Alpa, Cambo, or other similar camera. I was able to rent the cambo for an annual report and also used the Horseman SW for a book cover project. These cameras have a lot more in common with a 4x5 than with an H1 or 1ds.
