2015 – May – Focus Stacking

Focus stacking is used when ever you want … but mainly when you have an object that goes outside of the depth of field and you want to get the whole object in focus.
Normally, you can do this by increasing the length of time that the shutter is open for, and by changing the f-stop, although this isn’t always a sure fire way to get a result as the shutter being open for longer means more chance of over-exposure.
Focus stacking reduces this risk as it allows you to set the correct exposure throughout the stack images, as you only have to expose for the bit you are shooting.
It’s great for shooting macro – where you normally have a shallow depth of field – but can also be used on landscape to ensure a truly front to back sharp image.
