Manza Hotel test shoot.

The story continues…

Attached Kirk baseplate to camera so I can mount to tripod.

Drove to Cape Maeda. Set up tripod.

Set aperture to F11. Took a photograph of the Manza Hotel.

Hung around for a couple of hours chatting to Nate, Luna and Akira. Unfortunately the sky clouded over so there was no spectacular sunset.

I learned how to set copyright information, and  change colour space from sRGB to AdobeRGB.

Returned home  and copied files. Uploaded small res. image to blog and full size image to Flickr.

I am sure most experienced digital photographers will be shaking their heads, looking at the blown out highlights in the cloud by the hotel. I realize it’s a rookie mistake, and with time I will learn to use the histogram, but I am still amazed by the witchcraft that makes my pictures appear instantly on the back of my camera. More confusing  is the purple fringing that seems to be appearing on some of  the windows of the hotel. You will have to look at the full size file on Flickr to see this. Any ideas? (Lens? Color Space? Jpeg/RAW?…)

The detail in the shot is fantastic. Very pleased.

An interesting discovery was that when reviewing  pictures the images automatically orientate themselves correctly whichever way you are holding the camera (In a similar way to an iPhone). Clever stuff.

    I would disagree on purple fringing and tend more towards moire colors, as you get purple and some green colors at the windows, wich are the typical moire color patterns. Remember, the 645d has, as most MF DSLRs, no AA-Filter before its sensor.

    Will you do a comparison of how shooting digital affects your work-flow versus shooting film? Beyond just missing out a couple of steps in the process, there must be quirks you couldn’t have foreseen when shooting digital?

      That sounds like a great idea Sam. You’ll have to give me a while to get used to the camera and develop a workflow, but I will do a comparison.

    Congrats on the new camera Chris, I think you are in for a new and wonderful experience…and those megapixels are going to give you some serious cropping room. It was a great weekend for shooting, I am sure you already put some serious mileage on the camera. How are the lenses holding up on this?

      Hi John

      I’ve just stuck with the 55mm lens for the first few shots. I know quite a few photographers are very interested in the results of using 67 lenses and an adapter so I’ll try and get some shots using that setup later in the week.

    I agree with mir52 and confirm this is NO lens CA!

    In their race for extreme resolution, most digital MF cameras have removed the anti alias (AA) filter which however is mandatory with a Bayer sensor pattern.

    As a result, you get ugly color moiré if the contrast changes significantly from one sensor dot to the next. A slight defocus can help here. Also, some RAW converters try to recognize and minimize the effect. So, to shot RAW and select a good RAW converter can help quite a bit.

    I congratulate Pentax for their decision to leave the decision for or against an AA filter to the customer. AFAIK, the Pentax 645D can be ordered with an AA filter and this may be a good choice actually.

    Falk Lumo, that is very interesting concerning the AA filter choice, and a GREAT decision by Pentax. It would be wonderful if the other major manufacturers did this also imho.

    Thanks for the responses. I think I read somewhere that the decision not to have the AA filter was done to produce the higher quality images, and that there is the assumption that a person buying the camera will know how to deal with color moiré should it appear.

    As for RAW, this is the next step. I’m shooting JPEG for these first shots as I guessed people would prefer to see results as soon as possible rather than wait until I have got to grips with the digital workflow.
