    Alpa Videos

    Dear Forum Readers,

    My company has created a few videos on the Alpa camera system. Since there seems to be a lot of interest in Alpa with this group I thought some of you might be interested to take a look.

    I hope this is appropriate and useful to this forum.

    You can see them at either:

    www.youtube.com/optechsdigital
    or
    www.optechsdigital.com

    I welcome any feedback.

    Best Regards,
    Paul

    I really enjoyed watching those four videos!
    The Alpa 12 TC is so tiny!

    Thanks for sharing.

    Appropriate and Useful?
    Very

    Feedback
    - Not so sure about the developing theme of lightly colored button-ups. I'd go black turtleneck like Steve Jobs. That Alpa is so sexy; don't let it outshine you too much!
    - Never hurts to include a beautiful women where applicable!

    Really great first post Paul. Hope you stick around and continue to contribute!

    Re: Alpa Videos

    I'd also add one focus method to your Alpa focusing list. Preset "1-shot hyperfocal" (traditionally referred to as just "hyperfocal") and "2-shot hyperfocal" focusing.

    1-shot hyperfocal (traditional hyperfocal) most photographers know.

    2-shot hyperfocal method
    1) Determine the smallest-sized (largest #) aperture that you can use
    2) Find the closest point of focus which makes infinity critically sharp. That is your 1-shot hyperfocal point.
    3) Set camera to 1-shot hyperfocal point and find the closest point which is still in critical focus. This is your 1-shot hyperfocal near-limit limit.
    4) Find the closest point of focus which makes the 1-shot hyperfocal near-limit critically sharp. This is your 2-shot hyperfocal point. For consistent results allow a slight overlap.

    Once you've figured out your two points just put them in a note on your cell phone in case you forget (or if your inclined put a discrete mark on the lens at each point) and when you go to shoot just set to HF#1 and shoot, then set to HF#2. When you get home you can stack the two in Helicon Focus (or CS4).

    30-second illustrative sketch in photoshop attached.

    Re: Alpa Videos

    Do have a question re: the TC (or I guess any Alpa unit), any issues using a Mamiya/Hassy/Contax, etc factory FILM back -- via the required mounting adapter?

    Re: Alpa Videos

    Yes always good to see something on the Alpa

    As a long time fan and owner user I have to say ( somewhat ironically) that after much consideration - I haev decided to go teh arTec route for my big boy system ( I will keep my 12WA for walk around fun)

    The artec gives me inbuilt and elegant focussing via freznel and magnifying loupe - and a sliding back so that I dont have to worry about dust and stuff
    It also gives me inbuilt geared tilt as well as vertical and horisontal shift.


    Don - thanks for posting a clear diagram of a simple and neat methodology for people to use. I will add another dimension to the methodology by seeing how I can incorporate some tilt to add to the potential.

    It will take a few weks for my kit to arrive.

    Re: Alpa Videos

    Contax or Hasselblad filmbacks can't be used on an Alpa.

    An adapter for Mamyia RB backs is available.
    Or the 2 dedicated 6x9 backs, one built by Mamyia, one by Linhof.

    Re: Alpa Videos

    It is possible to use a Hasselblad film back with an Alpa if you first wind it on to shot number 1 on a Hasselblad body -not ideal, but possible.

    Re: Alpa Videos

    Thanks for answers on the film backs. Film or digital or both, the TC in particular looks like a kit a person could have a lot of fun with. Not cheap mind you, but when you consider the cost of a digital back....

    Nice job Paul, keep it up.

    Carsten,

    ALPA list adapters for Mamiya, Hassy, and Contax digital backs. (http://www.alpa.ch/index.php?path=pr...s_and_adapters) However, they say these adapters will not work with film backs.

    Re: Alpa Videos

    I need to watch them but I think I remember watching one of them but I agree any demo on how this stuff really works is well worth watching. I had a Alpa TC and loved it

    Re: Alpa Videos

    Dear Friends,

    Thank you for the kind words.

    We have many more video projects in the works, some just for fun and some more informational. Next week we hope to finish a fun project shooting the interior of a Maserati with the Alpa TC and 23mm Rodenstock lens.

    We would also like to show a six position stitch with the Max and the stitching adapter.

    We will post them as soon as they are complete.

    Best wishes to all for a great weekend.

    Paul

    I have a question about the segment in the first (?) video where you show the view of the three individual files before stitching.
    Had these files had an LCC correction run on them before you presented them to us
    or are they natively that free of color cast when using the degree of camera
    movement you showcased?

    Thanks,
    Mark

    Hi Mark,

    The view of the three files has no LCC correction at all. We also had a reasonable degree of rise on the lens to get less roof and more view (you can see this rise when I changed camera position for the second series of three shots). This did cause a slight vignetting in the far left and far right upper corners. We did retouch for this vignetting in the final assembled image but the three separate files are shown exactly as shot.

    Best Regards,
    Paul

    portraits?

    So I have this weird idea...

    I've been on a three year struggle whether to "mf or not mf"... and the one thing that's been bothering me is the actual cameras. I really don't feel any of them to be compelling... but that's just me. And now I'm loving what I'm getting out of the a900/zeiss combination for my hand held work in good light.

    So... my question... for studio/location portrait work on a tripod, and we're talking deeper DoF fashion stuff at f/11 and smaller, has anyone used an alpa camera on people? I'm actually an architect by education and part-time vocation and am looking to do more architectural work and i LOVE the alpa cameras from a design standpoint as far as shifts/swings and simplicity... but it would be nice to tripod mount one and use it in the studio on some portraits from time to time.

    Am I Crazy?

    How are longer lenses on it? Say normal- to short-telephoto.

    Thanks!

    you could also go to their customers "photographers" websites

    I get a Magenta caste shooting with Hasselblad backs or Sinar back or Phase backs the amount varies according to what you are shooting and wether it is a wide angle liek a 23/24/28 or 35.. - this is an easilly correctable fact of life but I wouldn't buy an Alpa with Schneider or Rodenstock wides unless you are prepared to properly prepare and correct for these outcomes of close lens to chip distances with wide angle lenses.

    Re: Alpa Videos

    Paul

    The one thing I noticed watching the videos is that it appeared you did not turn off the back as you took it off to change orientation. I always thought that since the back is on and the sensor is "charged" (for lack of any better term) it was better to have the back off to eliminate or reduce the chance of attraction of dust. That's why I always turn my P45+ off prior to changing the orientation on my Cambo RS-1000.

    Am I missing something or just overreacting.

    It's no worse an assumption that the back would have a charge that would repel dust while it's on. Maybe by turing it off you're attracting more dust.

    It probably makes equal sense either way however I figure I'll just keep doing it the way I've been.

    Hi Don,

    I never have worried about this and it has never been a problem for me. It is actually no different than changing lenses on this type of camera.

    But, on the other hand, I don't want to be the guy that suggested for you to change your ways and then have it be a problem for you.

    By the way, very nice pictures on your website. I enjoyed looking at them.

    Best Regards,
    Paul

    Thanks Paul

    Never thought of that way (same as changing lens) however I normally turn the back off as I change the lens on the RS-1000 (never thought about it when I was shooting w/the Phase or Mamiya body).

    Thank you for the complement.

    Guess it boils down to whatever keeps you comfortable.
