I have many hundreds of images to choose from (I'll likely share more). Many of them were captured with a wide angle zoom lens, but this particular perspective seemed ideal for 50mm and I happened to have the Canon RF 50mm f/1.2L USM Lens in the MindShift Gear FirstLight 30L backpack I was carrying. I originally thought this image was captured with that lens, but ... this happened to be the last image taken with the Canon RF 24-105mm f/4L IS USM Lens prior to mounting the RF 50.
Using a "standard" or "normal" focal length makes keeping both very close and very distant subjects in sharp focus a challenge, even at f/16.
For this image, I focused on the foreground trees for one frame and on the background trees for a second frame.
For a simple focus stacking technique, I loaded the two images as layers in Photoshop
and used a layer mask to determine which image the foreground trees were showing from.
