The focus differential is the distance between the in-focus areas in each shot. you want to cover a wide depth of fieldġ0 shots, focus differential of 5 (hand-held).there are many subjects in your composition at varying distances from the lens.Generally speaking, you’ll need more shots if: (You can use either the Raw files or JPGs but keep in mind that the E-M10 II Raw files aren’t yet recognised by most post-production software programs.)ĭepending on the number of subjects in the shot, your distance from the subject, how much of the subject you want to capture, and your chosen f-stop, the number of shots and the focus differential required will vary. Knowing which values to choose is really a matter of trial and error, though experimentation and experience will help you make an educated guess. Instead, you must use a stacking software such as Photoshop or Helicon Focus. The camera itself will not stack the images. It allows you to take up to 999 consecutive shots at focus differentials between 1 and 10 in a fast burst. With the new OM-D E-M10 II, we now get a new mode called Focus Bracketing. (For an in-depth explanation about focus stacking, I suggest you visit this excellent article by Cambridge in Color.) E-M10 II, 1/200, f/2.8, ISO 400ġ0 shots, focus differential of 10 (hand-held) Although it is also used for landscapes, it is most frequently applied to macro photography because your depth of field will almost always be shallow with a macro lens, even at the slower apertures. It involves combining multiple shots taken at different depths of field to bring a subject into focus. What is Focus Bracketing on the E-M10 II?įocus stacking is a well-established technique used by photographers to extend the depth of field of their images. What’s so exciting about this camera? It all comes down to one feature: the Focus Bracketing mode. Now, nearly three years on from the release of the original E-M5, we’ve arrived at the most recent iteration, the E-M10 II. It was later followed by the E-M10 which introduced a Live Composite mode, and subsequently the E-M5 II, which gave us a High Res Shot mode. Then came the flagship E-M1 with its efficient autofocus system that works with Zuiko 4/3 lenses. The first E-M5 gave us in-body 5-axis stabilisation and Live BULB/TIME. And what’s great is that these features aren’t so much “technological gimmicks” as they are a reaction to the realistic needs and interests of photographers. It seems that with every new Olympus OM-D camera, we get at least one exciting new feature. Update: Olympus has announced firmware updates for the E-M1 and E-M5 II that include focus bracketing and focus stacking (E-M1 only) among other things!
