Flash Sync Speed – Tech Thursday

The last two Tech Thursdays I have posted about the leaf shutter lens built into the FujiFilm X100s, Sony Cybershot DSC-RX1, and some medium format camera systems. They have some special abilities over dSLR cameras when it comes to syncing with flash units. Allowing for a faster sync speed, you create outdoor photos in bright sun while retaining shallow depth of field.

Most hobbyists and professionals use dSLRs for making images. However, they are limited in terms of what shutter speed they can use with flash. Look through the manual that came with your camera to see what the sync speed is with your particular model. Some cameras sync at 1/160th of a second, but the fastest shutter speed I have seen with them is 1/200th of a second.

Feature Comparison

If we were to take outdoor photos as these shutter speeds, we would have to close down the aperture to not let in too much light and overexpose the photo. What would happen if you were to set your camera to a higher shutter speed? These were taken with a Nikon D4, and the flash was a moonlight connected by a PC-Sync cable to the camera. This photo is set at f/5.0 at 1/200th of a second, the flash sync speed of the camera:

The shutter is not open long enough for the flash to cover the entire frame. Eventually the entire frame will be black when the shutter speed is too high like at 1/1000th of a second:

The leaf shutter camera can still do just fine set at f/5.6 at 1/1000th of a second:

Tatay and his Camera

My dad and his Nikon at the Grand Canyon

From yesterday’s post, you can see I still like to get in front of the camera sometimes. My father was the family photographer. His Nikon was always around his neck, and he brought it on every special outing. Looking back, I am now much more interested in what he was shooting, what lens, what camera body, perhaps what film he was using. I’m thankful that my dad did not shy away from having his photo taken. It would have been a shame to have so many family photos, and not have many of him on film.

If you are the family photographer, be sure to get out in front of the lens! Spending all your time behind will no doubt make your photos better, but after so many years, family will want to see you in there too. Since my dad only had the big SLR camera, all of these were taken with other point and shoot cameras, or maybe disposables. With these subjects, it really does not matter how they were captured, I’m just enjoying looking back and the times that we took time as a family to visit places away from home, and spend time together.

Just writing this post, I thought of a new assignment for myself. With the evolution of Nikon cameras, they have decided to keep the lens mount the same. I should do a shoot with my modern cameras using only my dad’s old manual focus lenses. They still mount on my cameras, and maybe they will make some different images. Will I be able to tell the difference? I’ll give it a try – see if you notice the difference! Thanks to Tatay for getting good glass that I can still use. I’ll be sure that they don’t rust away on the shelf.

Brain Games – Fisheye Lenses

Brain Games at Tysons Corner Center - ©TimeLine Media

Tysons Corner Center

There was a very nice installation at Tysons Corner Center a few weekends ago. The display was very photo-centric and unique much like a lot of the content by National Geographic. Brain Games is a new show on the Nat Geo channel that describes how our brain interprets the visual data gathered by our eyes. If you watch this show, the demonstrations are mind-bending in the way that they show how our mind will digest information. Sometimes, there will be blind spots, sometimes the mind will fill in missing areas of information with its own data, not unlike “content aware” options in Adobe Photoshop.

To go along with this show, the display had 4 different setups that made for some great illusions when captured on camera. There were rooms that were setup upside down, some with drastically sized furniture that would change the size of people in the frame, and some used mirrors to trick the eye into interpreting the scene. I do not have any photos from my camera on the setup since the camera position was very integral in getting the effect correct. I tried in a few frames, but it did not work as well as their setup – a credit to the designers and builders of the display! So after getting some standard photos of the display and the crowd that was taking part in the demonstrations, I decided I need to get some sort of strange – brain bending angles to the photos.

Fisheye Photography

This is where the fisheye lens comes in. I rarely uses these on shoots. When you first get a fisheye, you will use it constantly for a week, then you struggle to find an appropriate time to use it, especially for client work. The extreme wide angle distortion makes it difficult to use with people, and architecture photography would be too unrealistic with these lenses. If you shoot weddings, there will likely be a handful of times during a ceremony or the reception where it would be nice to get an overall view of the venues with the fisheye. The one I have is the 16mm Nikkor lens which is not the best performing lens, and has not been updated with a new model in quite some time.

Although there are lots of people in these photos, I had the camera on a tripod to get blurred motion from people moving through the display. It depicts more of the drama and action while keeping all of the elements of the display sharp. In Lightroom, you can straighten the bulbous curves in the frame using the Lens Corrections panel in the Develop Module. I try both the corrected and the uncorrected versions before deciding on a final version. It really depends on what is at the edges of the frame as to which is the best for the photo. Corrected frames will really stretch the edges which is not as bad for structures as it is for having people in those areas. I am happy with how this came out, and now have Brain Games on the TV watch list!
