ExpoAperture2 Depth-of-Field Guide

"I am extremely pleased with the purchase of my ExpoAperture2 Depth-of-Field Guide.  It takes all of the guess work out of determining the areas that are in focus when using my 4X5 camera.  I would highly recommend the ExpoAperture2 Depth-of-Field Guide to all large format camera users.

Additionally,  I found the customer service to be outstanding.  Every aspect of the service I received was top notch and first class.  Many other companies should take a page from your company's play book."

The ExpoAperture2 Depth-of-Field Guide is a great tool!

One question that I ask digital photographers is: "How do you take a photograph of a subject that's eight feet away and you want to focus on it as well as everything 3 feet behind while everything else is blurred?"  So far, no one has been able to give me an answer, except to say that they have to guess...and hope for the best.
 
Then I show them the ExpoAperture2 Depth-of-Field Guide and explain how this tool can tell them precisely how to adjust for their intended depth of field. Several of my friends have purchased it since.
 
If you do serious landscape work it's inevitable that you will be concerned with depth of field. If you utilize a zoom lens it won't have depth-of-field scales on them. The only other option is to use the depth-of-field preview button, which many DSLRs have. However, If you've ever used one, you'll notice that it's so dark when the button is depressed that you can hardly see the image.
 
The ExpoAperture2 Depth-of-Field Guide is the answer.

"I just received my Depth-of-Field Full focal range 2 disc kit, and must say I am rather impressed. Very nice product. Your Quick start guide was very handy, I didn't even have to use your cd disc that accompanied the guide, but I'm sure to get to it. I thought I'd let you know it will compliment my shooting nicely. Also, the shipping was very prompt. Nice job."

"I found the 'Depth-of-Field Guide' very useful.  I hugely recommend the guide,  especially for those who do not understand the aperture and depth-of-field relationship."

"Thank you for the 2 disk kit, and of course for the gummy frogs. I'm sure that I will enjoy them all. I compliment you and your company on your responsiveness (to all my questions/comments about video sensor depth of field), for your cool product, and for your way cool frogs!"

"I'm a 65 year old photographer that has just gone digital from many years of using medium format with prime focal length lenses.  In my previous life I always used a tripod, mirror lockup, a good incident light meter and set my lens to the hyperfocal distance to maintain quality.  In changing to digital (because of declining film availability) I want to use the same methods for the same reasons.  The fly in the ointment was I now use zoom lenses and lost the ability to set hyperfocal distance.  When I discovered your wonderful tool the sun came back out in my world.  People who always used zooms and accepted whatever D.O.F. they got may not fully understand what you have created but I certainly do. I hope my comments are welcome."

"I speak at a lot of seminars, conferences, and expos on behalf of the DVPA (NAB, PhotoshopWorld, WEVA, etc).  I've been looking for something to recommend in my classes for those who need to better learn about Depth of Field.  And now I have it!  The ExpoAperature 2 Depth-of-Field Guide is perfect for anyone who wants to learn how to control their focus."

"For teaching depth-of-field, I can't think of a better tool."

"As a tool for the teaching or learning of photography, the... Guide is peerless in assisting understanding of one of the most important and least understood areas in photography - depth of field. Because of the simplicity and clarity of its design, and its orientation, it is the best graphic aid in teaching depth of field that I have ever seen.

I have now taught several dozen beginning photographers from San Francisco State University the principles and application of depth of field and never in my teaching career have I found students to so quickly and profoundly understand the concepts and their application.

I have decided to totally delete the conventional depth-of-field tables from my textbook, and offer the... Guide as their sole and exclusive replacement."
