Using a computer screen or TV as a backdrop is a fun way to spice up your indoor photography and videography work. In the related video I experiment with using a 19″ IPS LCD screen as the background in a few situations like miniature diorama photography with Legos, as a backdrop for a book, and adding interest to photos of  Karuta playing cards . I also filmed a few quick video sequences using a “Lazy Susan” to spin around a product for b-roll clips.  Links are potentially affiliated in this article, I earn from qualifying purchases!  Even a small 19" screen can work alright. My related YouTube video about this project. For equipment I was using a Canon EOS M5 with a Sigma 56mm f1.4 DC DN lens. That focal length gave me enough of a narrow field-of-view that I could work with such a small computer monitor. If you try this out and use a larger screen you should have more flexibility in focal lengths. Here are a few examples of what can be achieved… If you want your own se...

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 Chicago Comic Con. I made the most of it and ended up with around 100 photos of cosplayers and costumers. Friday at the convention: Pentax K-5 camera Pentax FA* 24mm f2 lens Sigma flash, diffuser, green flash gel placed in the diffuser. Time was limited, so I used one camera and lens with a focus on covering what cosplay I ran into. I was pleasantly surprised by the level of activity so late in the day. There were plenty of people cosplaying, even more so than I remember seeing on the Sunday of Comic Con 2011. My intention with the flash gel was to equalize the color of the flash light to ambient. The gel ...

I went on a big excursion recently where I used off-camera flash and full manual setting control. The nice thing about Pentax cameras is that you can have a few conveniences in manual that make setting changes faster and more accurate.  Cameras and  Cactus V5  flash transceivers. For example, changing the green button functionality from “P Line” to “Av Shift” allows you to get a quick exposure reading that changes the aperture, but not the shutter speed. This is important when you are limited to the flash sync speed of your camera, because you don’t want the green button to select a shutter speed that will be too fast for the flash to function with. “P Line” (aka. Program Line) bases your sampled exposure on a number of simple options. There is one for maximum sharpness (MTF), one for maximum background blur, one for action, one for landscape, and so on. The flash sync speed is the fastest shutter speed that still allows for your camera’s sensor to be completely visible w...

I wanted to go over the techniques I used at this convention partly for a personal log and also for anyone who might find the discussion of techniques interesting. This really is just a selection of techniques, but a good overview nonetheless. Primary Equipment: Pentax K-5 camera body Pentax FA 31mm f1.8 lens Sigma 530 DG Super flash + Stofen diffuser (used in certain situations) Pentax DA 50-200mm WR lens (fashion show and masquerade) K-7 + DA 55mm f1.4 SDM (only used them once for a private shoot) Kata 3N1-22 backpack Camera modes: The K-5 camera body has 5 selectable setting modes allowing the photographer to select and save settings in those 5 slots. I used three slots primarily, which I will go over below. I’ll also include any other factors in how that mode was used. USER Mode 1 (flash photography): – ISO fixed (usually 80, but a range for creative and testing reasons) – Av mode (usually large aperture) – Exposure compensation like -2 inside, only slight reduction like -2/3rds ou...
