ExpoAperture Depth of Field Guide...Sharper Images and Selective Focusing The ExpoAperture Depth of Field Guide is the simplest and fastest way to determine the best aperture setting for selective focus in any situation with digital SLR, 35mm and medium format (120/220) cameras. It is calibrated to work with 18mm to 400mm focal length lenses. You can determine the maximum usable aperture and precise focus point for all depth-of-field circumstances. Gain better creative control over your images with the quick reference depth of field guide. 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 a great graphic aid in teaching depth of field. The ExpoAperture Depth of Field Guide allows the photographer to obtain the greatest possible image sharpness where he wants this sharpness, and to determine where that zone of maximum sharpness will begin and end. The ExpoAperture Guide provides an exceedingly simple, fast and convenient means for determining the right relative aperture number for use with film or digital SLR cameras, with a range of popular focal length lenses, and for a depth of field ranging from 12 inches to infinity.

4.0 out of 5 stars Handy Depth Of Field calculator For Nikon D80, & Other DSLRs, August 4, 2008

By	Michael Zdyrko "Mike" (Camden, DE USA) - See all my reviews (REAL NAME)

Since I received ExpoAperture Depth of Field combo pack and learned How to use them, my photography skills have improved. I am also impressed with the shot images I have been getting when using these guides. They have allowed me to improve the taking of better depth-of-field shots the first time. It moght take a moment of your time to work the dials to calculate and come up with the proper f/stop setting, but it saves time in the number shots you have to take to get it right the first time. Your PC time is reduced in clearing/correcting up your shots.

You can also set the f/stop you want for your shot and calculate at what distance the depth-of-field will be sharp which allows you to determine if that's what you want to shoot at.

It was not easy at first. The instructions I got with the order were on cards and to me limited. I went to the ExpoImaging site and printed the manual for myself. Studied it and carried out the instructions in different variables and was impressed with the results. Since I have a Nikon D80, I set my dial to 1.5x and 20 microns. I taped the settings on my dials to prevent movement of dial and having to reset each time I was to use the guide. I did this since I have a Nikon D80 only. You have three ways in which to calculate your depth of field and select the way you want to calculate for different variable of shots.

The guides help you to determine the maximum usable aperture and precise focus point quickly for all depth-of-field circumstances in any situation. The guides have reduced my guess work and improved my creative control over my image shooting. In a true sense, these guides are simple quick reference guides that are teaching me or assisting me in understanding photography better in understanding depth-of-field. It seems I was limited in knowledge. My landscape shots have greatly improved as well as other shots when clarity and sharpness are important. The ExpoAperture guide has allowed me to improve on my image sharpness twice fold and to determine where maximum sharpness will start/begin and end.

The two ExpoAperture guides help you to determine the right relative aperture number with your DSLR with the range of focal lenghts, and for the a depth of field ranging from 12" to infinity. Here are some examples(from Guide Manual) you can use these expoaperture for:

1. The photographer is using a 35mm film camera or a DLSR with a 50mm lens and wants a depth of field of 6' to 30'. What aperture should the photographer use to achieve this depht of field? Nikon D80=f/22 or f/28. (they help you to figure out the correct aperture you need for the distance you want to get in focus/sharp).

2.The photographer is using a DSLR with a 1.5X crop (Nikon) factor, a 45mm lens stopped down to f/11 and is focusing on a subject 7 1/2 feet away. What is the resulting depth of field given this photographer's settings? Nikon D80= 6'to 10' will be in focus (they help you to figure out what will be in focus in front of the subject as well what will be in focus behind the subject and if this what you want).

3. A photographer is using a medium Format film camera that produces a 6 x 4.5 cm image and an 85mm lens stopped down to f/22. What is the hyperfocal distance for the photograher's shot? Nikon D80= 20' hyperfocal lenght...everything 20' and on to infinity will be in focus.

For Nikon owners, these guides will work with the following cameras; D200, D80, D2X, D2Xs, D100, D70, D70s, D50, D40, D40X, D60, D2H, D2Hs, D1, D1H, D1X. For other DSLRs (works for many Canons), you might want to check out the ExpoImaging site to see if it will work with your camera and if they are calibrated for them. The dial on the guides work with the following Focal lenghts: 15mm, 16mm, 17mm, 18mm, 20mm, 22mm, 24mm, 28mm, 30mm, 35mm, 40mm, 42mm, 45mm, 45mm, 50mm, 55mm, 60mm, 70mm, 75mm, 80mm, 85mm, 90mm, 100mm, 105mm, 120mm, 135mm, 150mm, 1`80mm, 200mm, 250mm, 300mm, 350mm, 400mm. Also included on the aperture dial are the f/stops which also includes the 1/3 stops from f/1 tru f/64

If you are new to photography, still learning, or want to improve your skills, this is for you. I thought I was good, well now I am better. When I read those books on exposure etc, I understand them alot more now. My chances of getting better shots in the field have improved with the presence of these two guide in my pocket. They do come with two plastic sleeves that hold them and protect them from the elements. This is a 5 star item. I set at 4 star accidently. Recommend.

5.0 out of 5 stars Camera Disks, September 17, 2008

By	Howard L. Hilliard - See all my reviews (REAL NAME)

The Nikon D200 is a very nice camera. Very nice, but difficult to learn to use. I purchased these to help with that. They work real well.
