Pentax Lenses: Auto-Focus (AF) Sound Test Roundup

I noticed people in general are interested in how each lens sounds (myself included), so I thought it would be helpful to put together a video demonstrating a set of lenses and how they sound when doing auto-focus (AF). This set is Pentax as it is the brand I use currently. The other benefits of this video is that you can get a feel for how the lens handles and … Continue reading

SD Card Speed Testing (Secure Digital Memory Cards)

The latest speed testing article (October 2017) is here. Most of my largest articles happen on a whim. I think of an idea and then keep scaling it up as I think of ways to make the article even more interesting and useful. My initial though here was to see how my collection of SD memory cards faired write-speed wise. I found out that Ubuntu Linux has a disk benchmarking … Continue reading

Jury-Rigging: Natural Vignetting (Dark Corners)

Why bother using Photoshop to do “artistic vignetting” when it’s as simple as attaching something to your flash unit that distorts and shapes the light? The answer would probably be lazyness, but Photoshop probably can’t produce the such unique lighting as I’ll be showing you below! First, let’s start off with the result: The goal was a sharp well lit subject with unique unevenly darkened corners. Here is a picture … Continue reading

Pentax At It Again (Colored Cameras)

This is of course a Japan exclusive, but it was recently announced that Pentax will be coming out with even more color combinations for their entry level camera, the K-r. Here is the press-release in Japanese: http://www.pentax.jp/japan/news/announce/20110420.html What I find most interesting here is that two of the cameras would be pretty decent in field situations as they would naturally fit within the surroundings. Especially the brown and camouflage one … Continue reading

Video Test: High Speed To Music

I finally got around to editing a 5 minute clip of the last convention I went to (the 2011 c2e2 Chicago Comic & Entertainment Expo). My intent here was to make something high-energy, so I found a fun high BPM song on ccmixter.org called Feeling Dark (Behind The Mask) by 7OOP3D. The final video ended up being only around 1 minute 30 seconds because I sped up the footage quite … Continue reading

The equipment: – Two Yongnuo YN460-II set in S1 mode at 1-3 bars of power. They were mounted on Flashpoint stands. – Camera was a K-5 and DA* 55mm f1.4 lens. … Continue reading

Off Camera Flash With A Classic Fruit Bowl

I wanted to get some practice today with using off-camera flash and food. Lighting can make or break a scene, so it’s always a good idea to get as much practice as possible with controlling light. My goals were to try and get some mood lighted images as well as fully lit images by relying on the two flash units as a primary light source. The equipment: Two Yongnuo YN460-II … Continue reading
