Exciting News!

iPad Version

Several months ago I had an idea. The idea was based on my own struggles with exposure when I was starting out in photography. This e-book book has been designed to give you a solid foundation regarding exposure as you continue to build your own photographic skills.


Within these pages you will find information about ISO, Shutter Speed, Aperture and how they all work together. You will also gain understanding of how your camera meter works, what the different exposure modes represent, and how to best use the modes.

This book was designed to be used specifically with the iPad and if you are an iPad owner then you can get your copy from the iTunes Store here:  https://itunes.apple.com/us/book/understanding-basics-exposure/id570851846?mt=11#

Now, if you are saying “What about me? I don’t have an iPad!” Well, I’ve got you covered. If you follow this link you can download a PDF version here:  http://www.lulu.com/shop/jason-eldridge/understanding-the-basics-of-exposure/ebook/product-20453300.html


Cost: $2.99 for either version

Understanding Exposure (Part 1 of 3)

There are three main factors to consider when you look at exposure.  Shutter Speed, Apeture, and ISO.  Below is Part 1 of 3 on understanding exposure.  I will likely do a wrap up after part three to include the camera meter and histogram so stay tuned.

Shutter speed
The shutter speed of your camera is the measure of how long the shutter remains open to expose the sensor. Any motion that occurs while the shutter is open will show on the image. (the faster the shutter speed the more likely you are to freeze the movement). Shutter speeds are based on the doubling or halving of seconds. The following is a general list of the most common shutter speeds from long to short: 1/15, 1/30, 1/60, 1/125, 1/250, 1/500, 1/1000, 1/2000, 1/4000, 1/8000. As you can imagine the 1/8000 of a second shutter speed would just about freeze any movement.  The shutter speed for Image 1 below is 1/20th of a second.  This by no means freezes the movement but you can see that much of the movement was stopped.  The shutter speed for Image 2 was 1.1 seconds allowing the movement to blur the image.  Really it depends on what type of image you are going for.  If you have any questions please feel free to contact me.
