    Thank you. Hard to believe that it took me exactly 50 years to get there. It is rather inconvenient because it is out of the way, far away from Tokyo and other big cities, and I wanted to go in winter when there is snow. In the winter when it is cold is when the […]

    No excuses. Had not shot with the RX1 in a while. Bracketing never occurred to me and am not sure that it would work if handheld. One thing for sure, the free version of Capture 1 for Sony is lacking in essential tools that are and were provided in Lightroom. Time to make an upgrade. […]

    I was very interested to read David’s history of the alpha system, however there is an omission which concerns me. In 1984/5 I took out a provisional patent on using infra-red communication to link a flash or incident light meter and a camera. Exposure information was transmitted directly to the camera and the shutter could be fired from the meter. I sold the patent to Minolta and they brought out the Flashmeter IV and the 9000 camera which could be used together. Sadly they didn’t engineer the system as flexibly as I had planned and users had to purchase the expensive meter as well as an attachment to fit on the flash shoe of the camera — I still feel that this was why the system didn’t achieve the sales I had hoped for. In addition the Minolta version had a serious flaw in that out-of-range information wasn’t communicated properly to the camera, For example, if the meter suggested f/2.0 at 1/250 and the camera had a f/2.8 lens, no error message was created and exposure was made at f/2.8 and 1/250.
    My system required a very simple light receptor which communicated by an infra-red beam to a receptor on the camera and then the camera’s own computer processed the exposure information. Out-of-range exposures would then trigger an error message on the camera. As described in the patent, the system could be used on video as well as still cameras.
    I feel this is another example of how far in advance of other makes Minolta were and how they so often failed to interest the professional world.
