Two posts in one day—what’s with that? Let’s face it, my previous post today was a bit of a cheat—it was the same image I posted yesterday with a little colour change. Not exactly an earth shattering post, but it made my son very happy and so it was worth it.
OK, if my previous post was a cheat, then this one is a tease. Think of it as a trailer for an upcoming movie post. Actually, I will probably need to spread the information over a couple of posts.
The photo above is my first attempt at stacking images: a highly magnified picture of a common sow bug or woodlouse (order Isopoda). It is the result of 24 different pictures—each taken with a slightly different focus—combined together to create one image that has much more depth of field than could be normally achieved at this magnification.
The photo below shows one of the 24 images. Compare the depth of field to the picture above. Cool isn’t it?
In the next couple of posts I’ll talk in detail about the equipment and techniques I used to take these photos and the software I used to merge them.
The stacked photo at the top of the page is far from perfect. The composition and lighting could be better; the focus is not consistent throughout and there is a lot of noise. Clearly I have a lot to learn about taking and editing a stacked image. So I’ll just have to take a lot of photos and keep working on my technique. Boy is this going to be fun!
The technical stuff:
Camera: Olympus E-620 digital SLR
Lens: Zuiko 50mm F1.8 reversed on an Olympus OM auto bellows
Settings: manual exposure (F5.6 @ 1/125 sec)
Lighting: Olympus RF-11 ring flash (manual; 1/8 power)
