OptimumCS-Pro calculates the settings that minimise the combined effects of defocus blur and diffraction, for the sharpest images the laws of physics will allow. This is functionality, based on solid optical science, available nowhere else. The difference between using the optimum aperture and using the aperture derived from a standard depth of field scale or calculator is not a trivial one.
Using the latter, you can, in some situations, lose half or more of your image resolution for near and far objects. Instructions in Brief. Setting Focal Length. Measuring Distances. The Aperture Scale in Cinematography. Customising the Distance Scale. Object Space or Image Space?

If you are satisfied that the image will be sharp enough to meet your needs, set your camera at the indicated focus distance and aperture, and shoot. Using a smaller aperture larger f-number will degrade the image due to the effects of diffraction, while using a larger aperture smaller f-number will degrade it due to the effects of defocus blur.
Optimum camera settings are independent of camera format.

Set the actual focal length, as printed on the lens. The rapid selection buttons, located above and below the focal length scroll wheel, are intended for very rapid setting of particular focal lengths. Some cameras provide a digital readout of focus distance in the viewfinder. For obvious reasons, the aperture scale on this app is calibrated in f-stops.
Cine lenses, however, are calibrated in T-stops, and most lenses these days do not include a secondary f-stop scale. Is this a serious problem?

For modern prime lenses and relatively simple zoom lenses, light transmission is so high that T-stops are close enough to f-stops as to render the differences unimportant in practice, certainly for our purposes being a wee bit off the ideal aperture setting has little effect on image sharpness.
You may choose between 3 different distance scales via the buttons at the top left of the main screen. All scales read from 0. The first scale emphasises the near distances and is more useful for work with very wide angle lenses. The second scale is a general purpose scale. The third scale emphasises the far distances and is therefore more useful for work with quite long lenses. Note that the first scale is not intended for precise macro work nor is any other scale, for that matter.
Do not try to use this app for macro work.

The facility to set the wavelength used in the calculation of optimum aperture is intended for the benefit of those photographers and cinematographers who shoot in the infrared or ultraviolet parts of the spectrum. For general work, leave the wavelength at the default value. If you are shooting in the infrared or ultraviolet , select a wavelength roughly in the middle of the spectral range in which you are working. That sensitivity, however, steadily decreases as it approaches that limit.
So, peak sensitivity of your filter-sensor combination may be at, say, nm. That, therefore, is the wavelength you would set.
Clearly, making changes to the wavelength setting is for users who are happy to do some research. Be aware, though, that there is no need to seek great accuracy in determining where on the spectrum the peak sensitivity of you filter-sensor combination lies.
In finding optimum aperture, the effects of changing wavelength are not huge.
Fujifilm FinePix JX600 Key Features:
If you set, say, nm instead of nm, the difference in calculated optimum aperture will be too small to be of practical concern. You have a choice of thinking and working in object space or in image space. This is a very different type of scale specifically for use with view cameras. Creating a sharp image also entails attention to:. Motion blur can be overcome to some degree if desired, of course by shooting at a faster shutter speed.
This may entail shooting with a wider aperture than the optimum aperture indicated by this app. For information on shooting at other than the optimum aperture, tap the info button above the Blur Spot Diameter display on the main screen. With regard to vibrations, we all know what to do: Use a quality tripod or, at least, a monopod. Image-stabilising lenses can help. Make sure that, on the Settings screen, you have selected the Image Space option.

Focus on the nearest object that needs to be sharp. Note the distance between the front and rear standards. Focus on the furthest object that needs to be sharp. Again, note the distance between the front and rear standards.
The optimum focus distance is half way between the two distances.
The difference between the two distances is the focus shift. Input this into OptimumCS-Pro to instantly find the optimum aperture.

Optimum focus distance and aperture, when found this way, are independent of focal length. The focal length input function is therefore disabled. This astonishingly simple, elegant and uniquely effective method was developed by Paul Hansma and serves as the basis for the optical science behind OptimumCS-Pro. Make sure that, on the Settings screen, you have set Object Space as the distance scale option.
The distance scale on a tilt-shift lens measures actual distances to objects only if no lens movements have been made.
Carry out all lens movements this must be done before the following steps. Enter those values into OptimumCS-Pro, even if they seem very different from the actual distances to the objects. Set the aperture to the value indicated by OptimumCS-Pro. Why does this procedure work? OptimumCS-Pro is not a depth of field calculator—its functions are quite different.
There is, of course, still a place for depth of field calculators. Also, please be aware that OptimumCS-Pro is designed for single-shot photography.
Again, more info is available at www. You will find that OptimumCS-Pro is based on mathematically sound and empirically tested methods, and may thus have confidence that it performs as advertised. Use the scroll wheel to set the focal length of your lens. Slide the pointers to set the distances to the nearest and furthest objects in the scene you are photographing.
Set your camera to the indicated focus distance and aperture You've made the sharpest possible image. This marker shows the blur size for the objects at your distance extremes so you know how sharp your image will be. George Douvos.
