How do you determine exposure?
You can use a separate hand-held meter or you can simply guess. With a meter you ensure optimum precision but if, on the other hand, you choose to guess the exposure, the quality on negative films may well astonish you. However, you need to err on the side of over-exposure: you will get extra shadow detail and increased latitude as opposed to under-exposure but this has to be balanced against the slight loss of sharpness and the increase in grain size.
On digital devices the integrated histogram replaces in many cases the light meter.
Photographic Know How
ALPA cameras are designed to be as simple as possible.
Mehr...Picture taken with the Hasselblad CF-39 back and an ALPA 12 SWA with Rodenstock Apo-Sironar digital HR 4.0/60 mm
Mehr...All Sinarbacks from Sinar and the backs from eyelike Jenoptics that are capable to synchronize via Flash Sync can get used with the ALPA.
Mehr...The ALPA is working with all actual digital backs.
Mehr...This is very simple: Just select the 'large format mode' on your Leaf back and connect the flash sync socket of the Copal shutter with the digital back.
Mehr...With a digital back this can be done simply and without problems: precise data is generated by the back itself in the form of a histo-gram.
Mehr...You can use a separate hand-held meter or you can simply guess.
Mehr...Please use our "Comparable Focal Length Calculator" based on Excel.
Mehr...The phenomenon of color shift (areas of red or green color cast) can occur when using wide angle lenses together with digital backs.
Mehr...The target group for this back type are fashion photographers.
Mehr...Yes, the backs from Hasselblad - and the former Imacon - work if they are not of the closed H1D and H2D type.
Mehr...Yes, the adjustable adapters can get shimmed in steps of 1/100 mm.
Mehr...ALPA cameras are used worldwide and in many kinds of fields, from fine art, architecture, landscape, travel, news, fashion, archiving to photogrammetry.
Mehr...Switching to a digital workflow is sometimes a complex process. Here our (so far) 12 golden rules to the digital path - or what is worth considering.
Mehr...The Rollei LensControl S is needed for all Rollei Electronic Shutters. We have uploaded the English version.
Mehr...Diffraction is a physical effect in general. In photography it is an optical effect that can limit the total resolution.
Mehr...What is distortion and how can it get corrected?
Mehr...Ever more frequently digital backs use ever-smaller pixels (at present more than 60 MP at 6 µm size).
Mehr...Adjustable back adapters (max. 3/10 mm, adjustable in single steps right down to 1/100 mm) with reuseable shims of various thickness are exclusive to ALPA.
Mehr...Not everyone wants to photograph digitally, and not everyone wants to do so exclusively.
Mehr...Answer: By Guestimation and laser meters
Mehr...Photographers who aim for high-end picture quality cannot simply “hang” a digital back onto the familiar old film camera.
Mehr...These are three unwelcome but usually removable side effects when photographing with digital backs.
Mehr...Shift, swing and tilt are purposeful displacements of the picture axis against the lens’ axis.
Mehr...All actual ALPA lenses in Copal 0 (except Apo-Digitar 5.6/24 mm XL) feature the interlock as standard equipment.
