I was a bit bored, so I thought I’d try something different.
It’s small flowers floating in a jar of water and shot in natural light.
All manual focus.
I’ve not got a macro lens for the Canon, and if these are anything to go by … I might not bother getting one …
All shot with a Sony macro lens on the Canon body, and manual focus
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.
I’ve downloaded a bit of software for my phone called Slingshot (www.brainylantern.com) that enables me to control the Canon 7d through my phone as if tethered to a computer. This gives me full control over the camera without having to be near it, as I can view it all on the screen of my Android device.
It can be pretty handy, especially when used on a 7″ or above tablet for checking focus on small objects as you can enlarge them on a bigger screen.
Anyway, I wanted to test the software, so off I went in to the woods; I don’t have a macro lens yet, so these were shot using an old MD fit manual lens, a MD to MA adapter and a Sony to Canon adapter.
