What to do during this very strange time in our lives? It is scary out there, so we are staying inside and doing our part to flatten the curve by creating images with humor, creativity and/or beauty.

We have also been photographing a lot using focus-stacking in-camera.
Focus stacking is the technique of taking a series of images, with the focus point at the closest to the camera and then moving it mm by mm towards the back of the subject. With dSLRs, focus stacking was tedious and took a lot of work in camera and in post-processing, and often requires extra equipment like focus rails, CamRangers, Cognisys, etc. Today there are are a bunch of cameras that will focus bracket in-camera, including the Nikon Z, Nikon d850, Fuji XT3, Panasonic and most Olympus cameras. The images are then layered into software (Zyreene stacker, Helicon Focus, or even Photoshop for the simpler series). Olympus cameras take this one step further and allow you to focus bracket, or to avoid the post-processing step and focus stack in-camera. This allows for greater depth of field, cleaner backgrounds, and more productivity.
How to focus stack: go to menu, camera 2, bracketing, focus bracketing, on. then choose focus bracketings (3-999 images) or focus stacking (3-15 images, EM1 mark 11 users if you only see 8 then you need to update your firmware), choose the differential (1-10, try 4-5 at first for most flowers and bug subjects). You can also focus stack with flash, the flash coordinates with the camera to recycle and go off for each focus slice.

Focus stacking with Olympus means that straight out of the camera (SOOC) your image is sharp front to back with a beautifully blurred background. Sometimes you just need to shoot at 2.8-f4 in order to have a pleasing background, other times you need focus stacking because the subject has more depth of field than f22 will give you.
I was photographing this preserved moth, above, when I kept hearing fluttering. This Cecropia moth had emerged early...
