17 Pearl, Reflection

While ordering the professional line photobook from Saal Digital, I was also able to get a paper sample set. In this article we will look at all 15 types in detail. I have two Youtube videos available if you are interested in seeing the photobook process (Design & Reveal, Photo Selection Time-lapse). I took three groups of photos for each print type (see my Youtube video here about taking photos … Continue reading

SD Card Speed Test Roundup October 2017

I’ve done previous articles here (first) and here (second). A decent amount of the cards here will be the same. The goal was to round up as many cards as I had on-hand to do benchmark testing on. I also did a bracketed camera test with the Nikon D600. Here is the companion video on Youtube. I used a Transcend USB 3.0 card reader for this test. Here are the … Continue reading

Proprietary Camera RAW formats and Processing

Youtube Video Link: I’ve been doing research to figure out what type of process I will need to use when I change camera systems. Sadly, Nikon and others like Canon are fixated on using their own proprietary RAW formats, so that means any new cameras that use a special format will not work with my current post processing steps. Even to the point in the past where some of the … Continue reading

My Photography Techniques at Chicago Comic Con 2012

Usually I write a summary at the bottom of my articles that are primarily meant to update viewers about new photographs. This time I’m separating the technical into its own article so that I can go into a bit more detail. On Friday I had attended a small photo session at Cantigny Garden in the morning and afternoon. Once that was finished, I had around 1.5 hours to spend at … Continue reading

Quick Pentax Lens Test: Parfocal or Varifocal?

I did a quick test on three lenses that I have to see if they are Parfocal or Varifocal. If you are unfamiliar with those terms, Parfocal is a type of zoom lens that does not have focus shift when the lens is zoomed throughout the focal length range. This is a great feature for video work because the photographer can achieve focus and zoom without the need to refocus. … Continue reading

Camera Lens UV Filter Test: Does coating make a difference?

I decided to do a quick test to see how my collection of 58mm UV filters damage image quality. I also took an image without a filter to see what difference using no filter makes. Why do I personally use filters? I want the added protection that a filter brings as well as the simplicity of cleaning a filter instead of the front element of the lens. I occasionally take … 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

Replacing the Pentax K-01 Grip

Here is my previous article about the Pentax K-01 I recently got. The only one available locally was a demo unit with a yellow grip. I personally don’t like that shade of yellow and wouldn’t feel right using it in professional situations, but the deal was good and I couldn’t pass it up. I was able to acquire one of those fake K-01 display models to use as parts. If … Continue reading
