DOF Slider vs Focus Lt hyperfocal DOF

Calculate depth of field before you take the shot. Choose your camera, then adjust subject distance, aperture and focal length with three horizontal sliders. See your focus limits update as you move. SEE WHAT STAYS SHARP A live scene shows your settings at work. Flowers, a dog, a house and distant mountains sit at real distances, and each blurs according to your focus distance, aperture and lens. Open up the aperture and watch the background melt; zoom in and the scene tightens. You can turn the scene's animation off in Settings. MADE FOR IPHONE DUO Stand it up and the results face you while the sliders lie flat under your thumbs. Open it like a book and results and controls each get their own half, clear of the fold. Close it and everything moves to the outer screen, with your controls in the side bar. Layouts move smoothly as you fold. READ YOUR FOCUS RANGE See the near and far focus limits, total depth of field, and the distance in front of and behind your subject. Check hyperfocal distance when planning a landscape or a scene with distant detail. CHOOSE YOUR CAMERA Browse profiles for modern digital cameras, vintage cameras and film formats. Each profile supplies the circle of confusion used in the calculation. ADJUST WITH ONE HAND Keep settings and results on one screen. Work in metres or feet and inches, with optional aperture snapping and haptic feedback. START WITH THE INCLUDED PROFILES DOF Slider includes free camera profiles and standard calculation ranges. Additional camera packs and macro, telephoto and extended distance ranges are optional one-time in-app purchases. Restore existing purchases from Settings. No ads. No subscription. No sign-in required. Calculations work offline with the available camera catalog; catalog updates and purchases need an internet connection.

Consider bying new lens? Need to work the math for a perfect shot? Use this depth of field and circle of confusion calculator to simulate the out of focus blur, depth of field and hyperfocal distance for different camera configurations, including the diffraction effect for small apertures. The blur values are measured in the pixels of the camera sensor. The blur simulation shows how much the infinity and the object will be blurred as seen on a 25 cm or 10 inch printout or screen. You can tap on the magnifying glass to switch between full frame view, to asses the size of objects, and 1/10 of the frame view, where you can evaluate the blur. The parameters are: *Distance* - distance to the object, *Lens type* - focal length, *F-number* - aperture setting, *Focus distance* - distance the lens is focused at, *Sensor* - the megapixel count of the matrix and the camera sensor size. You can use the *HYPERFOCAL* mode to set the focus value to the hyperfocal distance for the current F value. If you want to have both the object and the infinity in focus, use *AUTO HYPERFOCAL* mode, it will find the minimal F and the corresponding focus value. *AUTO HYPERFOCAL* will try to achieve the best possible result, but due to the diffraction effect of small apertures it's not always possible to get a sharp image, the simulation will reflect this. The last smart function is *MAX BLUR FOCUS* - given an object distance and F-value it will suggest the closest focus value which will keep the object still in focus, while achieving maximum blur for the background. The idea is somewhat opposite of the hyperfocal shooting - here your focus point lies between the camera and the object with the depth of field ending on the object plane, ensuring the maximum possible blur for the background at your given F value. This works well if you are forced to use a relatively high F number, but there are no other objects in the view which are closer than the target. The standard *circle of confusion* used for DoF, smart focus and max blur calculations is the sensor diagonal divided by *1730*, which is the so called Zeiss formula.
