![]() Once a Raw file is rendered, you can’t re-access the data in it, such as ‘recovering’ highlights or ‘filling’ shadows, without re-rendering it. It’s quick and easy to process a focus bracketed series of files process one file in the series ideally and then Sync the other files to it. These effects will be automatically adjusted during the merging process.īefore you combine a set of focus bracketed exposures, make all the Raw conversion adjustments you’d like to make to the final file. You may notice that In cases involving extreme depth of field, you may notice the relative size of objects may change between individual exposures. While using a tripod always delivers more reliable results, don’t let this stop you from trying this technique hand-held, especially with simpler sequences, like those used in landscape. Whenever possible use a tripod to make focusing during exposure more precise and registration during post-processing easier. However, for tethered shooting, you can use software such as Helicon Remote to take control of your camera and automate this process and other bracketed sequences like HDR and time-lapse. Unlike bracketing for HDR, it’s almost impossible to automate these types of bracketing sequences in camera as focus needs to be adjusted for each frame. When in doubt, make more exposures than you think you’ll need you don’t have to use them all when you stack the separate exposures, but they’ll be there if you need them. When dealing with extreme depth of field, like macro or microphotography, you’ll want to make more exposures, at least three, probably six, possibly more. Making three exposures is better one each for foreground, middle ground and background. ![]() At a minimum, make two exposures one focused on the foreground and another focused on the background. How many exposures you’ll need will depend on how much depth of field a scene contains. To do this you first need to make a set of focus bracketed exposures, optimizing focus in different image areas. You can extend depth of field beyond the physical limitations of any lens/camera system with multi-shot exposure practices and software – by compositing multiple exposures. How deep would you like your depth of field to be? The choice is yours. Two exposures combined to achieve infinite depth of field ![]()
