Description

This Depth of Field calculator is for both theexperienced and the novice photographer.

For the experienced it is a quick and easy way to check depth offield for both macro and non-macro shots and hyperfocal distancefor landscape shots. For the novice it is a practical means ofcoming to terms with the camera - discovering the effect thataperture settings, lens size (focal length), sensor size andlighting conditions have on an image.

The Depth of Field calculator will display how much of an imagewill be in acceptable focus, depending on sensor size, focallength, the use of a teleconvertor and the distance of the subjectfrom the lens.
For macro photography the depth of field can be very shallow andthis calculator measures that in relation to the size of the imageon the sensor rather than the distance of the subject (thisimage-size scale is etched on the barrel of macro lenses). Becauseof the magnification of a macro lens less light reaches the sensor;the consequence of this is displayed as the ‘effective’ aperture,in addition to the actual aperture that you have set. For example,at f/11 and the lens focused to take a life-size image on thesensor the effective aperture will be f/22. A teleconvertor has asimilar effect.

For macro photography, in particular, small apertures forgreater depth of field can be counter-productive and lead to lesssharpness over-all. This is because of diffraction – the spreadingof light as it strikes the edges of an aperture. This calculatorwill alert you to the onset of the noticeable effects ofdiffraction with a colour-coded ‘resolution factor’. Lightingconditions can also affect diffraction and so you can change asetting to take that into account.
You do have to enter the ‘crop factor’ of your camera’s sensor. Ifyou do not know this we provide a list from which you can select acamera maker and the select your camera from that maker’s list. Atpresent the cameras listed are mainly DSLR’s but the range will beextended on demand.

You may check a working version on my website before youbuy.
