I disabled Exposure Smoothing as recommended in the manual for the Canon 100mm and 180mm macro lenses. At high magnification, depth of field is extremely shallow, so in the Focus Bracketing Menu, I selected 40 shots, with the focus increment set to number 4 on the scale. I used a Canon EF 100mm f/2.8L USM macro lens set to just a bit less than 1x. In my initial test of the in-camera technique, I used the EOS RP to take macro shots of some flowering plants.
Best focus stacking software software#
As with manual focus-stacking techniques, the in-camera capture sequence is later transferred to computer-based software for compositing into a single high-definition image. Note that focus stacking requires a consistent frame and motionless subject a tripod is needed. For example, adding depth of field to a landscape at 50mm and ƒ/11 might require three shots at the upper end of the increment scale, while at high magnification, where depth of field is extremely shallow, the photographer might select 40 or more shots at the lower end of the scale.Įxposure Smoothing, when enabled, automatically compensates for changes in image brightness from one capture to the next. The number of shots and focus increment you choose will vary depending upon the lens being used, focal length, magnification and positioning of the depth of field within the image you have to experiment with the many possible combinations. In the camera’s menu for focus stacking, the photographer can control three variables: Number of Shots, Focus Increment (1 to 10 scale, with larger numbers indicating larger focus increments) and Exposure Smoothing. The method incorporated into the EOS RP moves the focus elements inside the lens at incremental distances based on the focal length, aperture and camera settings. I got my hands on a Canon EOS RP and started experimenting with its In-Camera Focus Bracketing feature. Now the industry has incorporated in-camera focus stacking features in a number of ingenious ways it’s offered cameras including Panasonic LUMIX, Olympus OM-D, Nikon’s Z 6, Z 7 and D850, and Canon’s new entry-level, mirrorless full-frame EOS RP camera. I’ve been using and writing about the manual technique, for both landscape and macro subjects as small as snowflakes, for several years.
Years ago, I was asked by the folks at Canon what features I’d like to see in future cameras, and one of my suggestions was an automated focus-stacking capability-dramatically increasing an image’s depth of field by combining multiple captures taken at different focus points. Canon EF 100mm f/2.8L Macro IS USM with and without a Canon Extender EF 2X III.
Lepp used the Focus Bracketing function of the Canon EOS RP mirrorless camera to capture 80 focus-stacked images of a single primrose blossom, achieving extreme depth of field at 2x magnification.
