Shallow depth of field is lovely. Edge-to-edge sharpness of your product is critical. So how do you combine the two? Focus stacking!
- Focus stacking is a really cool idea in macro photography.…Where you take a series of photos…and stack them together to create a composite…where more is in focus than could be normally.…Let me illustrate this a bit.…Let's say I'm taking a photo of this mask here,…and I want the entire mask to be perfectly in focus.…Traditional photography would say…that you would choose an aperture that would allow…the whole thing to be in focus,…so let's just say that this is the center point…that I'm focused on,…a very narrow aperture would only have this much in focus,…a larger aperture would have this much,…and so on and so on until you get the entire thing.…
There's a couple problems with this though.…First of all the center point is the sharpest area…and the farther you get away…the less in focus it's going to be.…So if you want this to be perfectly sharp…that means your focus range is probably gonna have to be…way out to here or so.…And that maybe fine,…it just depends on what you're taking a picture of.…If you had objects on your scene here or here…
