DIY Transparent Color Slide Digitizer

I was recently given the task to digitize transparent slides from the 1960s. The color transparency slides posed an interesting problem. Conventional scanning was difficult because the slides are small and are designed to be back-lit by a projector. There are dedicated devices available that can scan film negatives, but they are expensive and difficult to find. The standard scanner that I had wasn’t sufficient for the task because it … Continue reading

Examine and clean a Pentax K-7 rear dial.

The rear dial on my K-7 has been having issues for quite a while. Scrolling left especially didn’t work properly. The aperture would jump around randomly and even cause the camera to temporarily lock up. After my successful modification of the K-01, I was feeling confident enough to take the K-7 apart to see if I could do something about it. In the past I tried the old trick of … Continue reading

The K-5 body is still MIA, but I wanted to have two camera bodies available. I purchased a used *ist D camera body. That blurred coin in the image is a nickel, not a quarter! I just had the camera delivered a … Continue reading

Anime Midwest 2011 Photos

This weekend a friend and I went to a first-run convention called “Anime Midwest.” It’s one of many small conventions that a group of people have been running around this area for the last few months. It has a very different feel than something like Anime Central (23,000 guests this year). With anime convention, more is better in my book. Some highlight images: On Friday and Saturday I was using … Continue reading

Pentax K-5 & K-7 Video Out Usefulness

I hooked up my Pentax K-5 to my LCD screen a few days ago to test out the functionality. As you may well know, the K-5 and K-7 are able to display live-view to an HDMI screen (and presumably standard composite). My little test consisted of setting up the K-5 on a tripod hooked up to the LCD. I then filmed the LCD screen with my K-7 to display what … Continue reading
