In the previous post I used the excuse of a dull New Mexico day to do a single image macro of a Darkling beetle on a Damascus cauliflower. Because of the very narrow (mm size) depth of field, the resultant image was only acceptably sharp where I focused, ie on the beetle.
Today’s weather provided another excuse to work indoors, ie cold with hints of snow. However, as soon as I tried to recreate the previous post’s scene, I had the first problem: no beetle. It seemed to have just vanished. I was sure it was dead, but it seems to have simply got up and walked away!
So I was just left with my fractal cauliflower, which by now was showing some brown spots and damage.
Although I have several ways of taking macro focus stacks, my go to approach is the Promote Control: www.promotesystems.com/
I put my Canon 100mm F/2.8L on F/16, ISO 100 and a shutter speed of about 3s, set by Magic Lantern’s ETTR function. The depth of field being just over a 1mm.
The Promote Control allowed me to take about 25 (overlapped) images for focus stacking, by simply pressing the PC’s start button.
After ingesting into Lightroom, adjusting a few sliders on one image and syncing to the rest, I exported the images as PS layers and used the PS Auto Blend option, which pulled out the sharp areas of each layer.
A tweak with Fixel Contrastica 2 and a return to LR for a final ‘polish’.
Bottom line: macro photography is a great way to occupy a dull day. Although there are alternatives, I find myself going to Promote Control, as my sturdy workhorse. Although I didn’t use bracketing on this image, I could have: all automatically.
