Yep, I agree. Although, my attempt was the first attempt to focus stack two images of landscape. It's the learning curve for me. Two images, one focused on far distance and one focused on the foreground are two less because there is no area of the images in good focus that overlap. The image focused on the foreground (like a portrait) is completely blurred in the background, and the other image focused on the background is completely blurred in the foreground (like a portrait shot miss-focused). With no sharp region overlapping between the two image, the software can't find control points. Added to that is the focus breathing of the lens. So, in order to make it easier to stack focus, I should have used a tripod, and I should have taken 3 or more images for the stack, and I could also have raised the camera to a higher position to reduce the discontinuity between the forground subject and the background.

That, yes. I've been a little too optimistic thinking I could just snap two shots away and stack them later.
Originally posted by Wingincamera First I lock the focus on the near subject, then frame my shot which usually moves the focus point further into the frame. Then holding very steady I take the first shot which is pre-focus on the near subject then without moving anything quickly refocus the second shot which is correctly framed.
That's a brilliant idea.... I actually though about how how I could capture two images focused at two different points without touching the camera...pre-focus yes that's a good idea!
