All were taken from my bedroom looking through the window with a screen on it. The screen gives the light an almost grid pattern to its twinkle.

Depth of Field Calculator

Found on the DOFMaster Website

Depth of Field Calculator



Camera, film format, or circle of confusion


Focal length (mm)
Selected f-stop
Subject distance


Subject distance 10 ft

Depth of field
Near limit 7.6 ft
Far limit 14.6 ft
Total 7.04 ft

In front of subject 2.4 ft (34%)
Behind subject 4.63 ft (66%)

Hyperfocal distance 31.2 ft
Circle of confusion 0.02 mm

Use the actual focal length of the lens for depth of field calculations. The calculator will automatically adjust for any "focal length multiplier" or "field of view crop" for the selected camera.

Focal lengths of digital camera lenses are listed here.
Focus at the subject distance, 10 ft
7.04 ft
7.6 ft
14.6 ft

Focus at the hyperfocal
distance, 31.2 ft


Depth of field extends from
15.6 ft to infinity


Depth of Field Definition

Hyperfocal, near, and far distances are calculated using these equations.

Depth of Field: The zone, or range of distances, within a scene that will record as sharp ... It is one of the most creative and profound effects available to photographers.

Using Your Digital Camera, George Schaub, 2003


Image clarity or sharpness is not just a matter of focusing a lens on the subject. There is an area in front of and behind the sharp focus plane that is also sharp or clear, and the extent of this area changes, depending on the focal length of the lens, the focusing distance, and the aperture used. This three-dimensional area of sharp focus is called depth of field.

Lonely Planet Landscape Photography: A Guide to Taking Better Pictures, Peter Eastway, 2005.



Hyperfocal Distance Definition


Hyperfocal distance


... the hyperfocal distance setting ... is simply a fancy term that means the distance setting at any aperture that produces the greatest depth of field.

How to Use Your Camera, New York Institute of Photography, 2000.


When the lens is focused on the hyperfocal distance, the depth of field extends from half the hyperfocal distance to infinity.

Photography, Phil Davis, 1972.

This was just a fun photo to take. I set the ISO to 3200 and took the photo. It only took a 6 second exposure to get this look by using such a high ISO speed. To me, this combination of settings gives the photo a very old look.

Exposure: 6 sec (6)

DSC00303: Christmas Tree 1.7


DSC00303: Christmas Tree 1.7, originally uploaded by RMStringer.

Taken with the Kit lens 18-70mm on a tripod in BULB Mode.

I love how in the B/W photo you can see all of the shadows and light patterns that are on the wall behind the tree. I looks to me like an old photo where the wall has been discolored by the passage of time. The lights on the tree look like little lightening bugs that are living in the tree.

Exposure: 1 sec (1)
Aperture: f/5.6

DSC00234: Christmas Tree 1.4


DSC00234: Christmas Tree 1.4, originally uploaded by RMStringer.

Another in the set taken with the Quantaray 70-300mm lens. I let the photo over-expose to give it a very bright, blurry look.

I took this photo to look like a memory, not clear but blurry like a Christmas memory form many years past. You can remember the tree as a young child and the colors but not the clarity as with new memories.

Exposure: 9 sec (9)
Aperture: f/4
Focal Length: 120 mm

DSC00297: Christmas Tree 1.0, originally uploaded by RMStringer.

This was the first photo that i posted to Flickr from the Christmas Tree set that i did last night. I was exploring the various effects that different settings of the camera had on the different photos. This is just one of many that i took. IT just happened to make to Flickr where others did not. I love the light "pop" that this photo has. The brightness and sharpness that the Quantaray 70-300mm Tele-Macro has.

Exposure: 12 sec (12)

DSC00213: Christmas Tree 1.15


DSC00213: Christmas Tree 1.15, originally uploaded by RMStringer.

Using the 18-70mm Lens, BULB Mode, Optika Wireless Remote, Tripod and my time to get different exposures and f/stops!!

I think that this was a fun experiment in dealing with the wall color, the light setting in the room (non existent) and the Camera Settings. I got some really neat photos depending upon what lens was used and camera setting i used as well. I think that this is a really neat way to learn more about the camera and equipment that i have in my possession.

Exposure: 3 sec (3)
