Watch the Canon 7D Shutter at 10,000fps

March 5, 2015 By Eric Reagan

[youtube https://www.youtube.com/watch?v=CmjeCchGRQo&w=700]

This video from the Slow Mo Guys shows us a great look at the shutter movement inside the Canon 7D at a range of shutter speeds, all the way up to 1/8000s.

Screen Shot 2015-03-04 at 11.52.08 PM

It is a view we don’t ever really get to see even if we do understand the process of how a focal plane shutter works. Thanks to a Phantom camera that shoots HD video at 10,000fps, we get to see up close and in detail the mirror and shutter operation.

As you are watching, note the vibration of mirror on its impact and consider how that will affect image quality as much slower shutter speeds.

The following is from HDR Photography | A 3 DVD Comprehensive Guide to HDR Photography by SLR Lounge. We cover bracketed HDR, in-camera HDR, single-shot faux HDR, single-shot bracketed HDR, panoramic HDR and more! (more info).

What is a “Stop” of Light?

The concept of a “stop” of light is probably the most important concepts in photography, yet it’s widely misunderstood. In this article, we want to take you back to the basics to help visualize a stop of light and changes in exposure.

A stop of light is not a quantifiable unit of light entering the camera but rather a relative one. Therefore, increasing by one stop doubles the amount of light let into the camera while decreasing by one stop cuts the amount of light in half. [Read more…]

Photography Basics: Shutter Speed

January 27, 2010 By Eric Reagan

In our last Photography Basics article, we took a look into the basic principles of aperture and lens speed.  We learned that the aperture of a lens is a critical component to a properly exposed photograph and powerful composition tool.  In this article we are going to examine the fundamentals of shutter speed and how it will affect your images.

Hopefully, we will also be able to answer that frequently asked question . . . why are my photos so blurry? Frequently, the culprit is our shutter speed. [Read more…]

Pointless Example of Canon 1D Mark IV Shutter Speed at 10 fps

January 13, 2010 By Eric Reagan

This video of the Canon 1D Mark IV firing at 10 frames per second is mostly pointless; however, I still find myself watching it over and over thanks to the gadget nut in me.

Looks a little grainy, doesn’t it?  That’s because it was shot at ISO 25600 on a Nikon D3S.  A single overhead tungsten bulb supplied the light.

Stay tuned for more serious content on both of these new work horses.  In the mean time, watch the video again. ;-)

7 Photos That Show Motion By Stopping It

July 19, 2009 By Eric Reagan

Take the plunge by The artist (formerly) known as Gene

Shot with a Canon EOS 30D at 1/250th of second.

Last week, I touched on using motion blur to give a sense of speed and movement in a photo.  This week, we’re going to look at some examples where no motion blur (or very little) is present; however, these images still manage to effectively convey a sense of motion.

In each image, there is some element that helps convey motion.  In some images, it may be the primary subject that should be moving.  In others, it may be an element surrounding the subject – such as water.  By freezing what should be moving, these images give your mind a moment that you know and can sense requires motion.
