Selecting important focus point in stack
Posted: 03.04.2019 20:46
Hi there
I'm working on a focus stacked multi row panorama. It is quite a wide angle interior, but there are some things in the foreground that I want to bring into focus. However, there is one part of the image that has to be as sharp as possible (a bookshelf), and it's towards the back of the image.
I'm using a D850 to focus stack in camera, then stacking in Helicon, then creating the panorama in PTGui. All is working well except for one thing, and that is that the bookshelf itself is coming out soft sometimes. I think it is because the camera is focussing just a little before or a little behind the bookshelf when it shoots that part of the stack, and not nailing it exactly.
There are 2 solutions I am aware of, neither of which I like, so I am wondering if you guys have another way I haven't thought about:
1. Decrease the distance between shots in the stack, shoot more shots - I don't really want to do this as I am already working with hundreds of images, and the only thing I need to be tack sharp is the bookshelf
2. Shoot each stack manually (yawn)
Is there a way to shoot the bookshelf sharp, then shoot the scene from front to back, and somehow insert the sharp image into the middle of the stack in Helicon? As far as I am aware it doesn't like images not being shot in consecutive order if you want to use all methods.
Sorry if I'm missing something blindingly obvious, would love to hear your thoughts on the easiest way to approach this in terms of workflow.
Thanks!
