In-Camera focus bracketing - how difficult would it be?

Interesting thought Steve but I'm not sure that focussing can be achieved by moving the image plane, can it?

In-Camera focus bracketing - how difficult would it be?

Focus stacking is only any use if the subject doesn't move at all - so that pretty much limits it to studio work. Consequently a tethered option under PC control would be nice - but not absolutely essential as it can be done manually. TBH, like true HDR I generally can't be bothered to invest the...

In-Camera focus bracketing - how difficult would it be?

Even a more simple type of focus bracketing would be useful to cure small focusing errors. The camera could front and back focus by set amounts. This would be easy for Pentax to add to the firmware.

Interesting thought Steve but I'm not sure that focussing can be achieved by moving the image plane, can it? I really don't know for sure, but my sense is that it should be possible for the macro application that you describe as we are only talking about a small amount of movement. I would have thou...

Focus stacking is only any use if the subject doesn't move at all - so that pretty much limits it to studio work. Matt I have seens some absolutely brilliant stacked insect shots in the past but I must admit when I try the little buggers always move.

In-Camera focus bracketing - how difficult would it be?

It's quite easy just run the following: ; make sure live view window has input focus WinActivate, Live View: ; Take a series of pictures and adjust the focus after each shot Loop, %NumberOfImagesInSequence% { SendInput {F8} Sleep 3000 ; give DSLR Remote Pro time to take the picture ...

In-Camera focus bracketing - how difficult would it be?

I've always thought this would be easy to implement, and potentially very useful. Hence the other day. Perhaps one of the manufacturers (hopefully Pentax) will twig eventually and add it in. It could probably be done by software update - I don't think it would be a hardware thing. Robert.

I would love this feature. It's on my wish list, almost none of which the K-7 implemented.

[OLD THREAD, NEW SOLUTION] A new solution to this problem can be found . Awesome technology. If only we had open source firmware, we (read Mattmatic :lol:) could probably impliment it ourselves.

In-Camera focus bracketing - how difficult would it be?

If only we had open source firmware Sorry Peter, it doesn't work like that... it's much, much more than firmware! :( Light field photography works by a special lens element that produces an odd distribution of the light onto the sensor. IIRC, you ended up with 1/4 (or 1/16?) of the total resolution...

In-Camera focus bracketing - how difficult would it be?

On the focus stacking front, this has now been implemented on a number of p&s cameras. Please get it sorted Pentax! Another suggestion would be a hyperfocal mode. Would work as above with the start and end focus points selected but instead of stacking, the camera would select a suitable focus and ap...

It's sorta like a hologram but not requiring coherent light. With all the resolution issues, no doubt.

Also a solution ... maybe another reason to buy another make of camera.

I don't think so Mike. This is all pretty marginal stuff for most people.

In-Camera focus bracketing - how difficult would it be?

I should think macro shooting is one of the most popular aspects of photography (from what I have seen anyway). Probably a reason Canons MP-E65 is one of their most popular lenses .. hardy marginal I would have thought. Maybe I should have put: maybe another reason to buy another make of camer...

In-Camera focus bracketing - how difficult would it be?

Still don't agree, but that's OK. With focus stacking, in theory every time the focus point was changed the magnification would change. I presume the software corrects this, but does it do it seamlessly or are there odd side effects?

In-Camera focus bracketing - how difficult would it be?

Just did a 4 stack shot of a moth .. handheld so not as steady as I would like and the flash is a bit harsh but even so ... by , on Flickr All I did was take 4 shots in quick succession while moving the camera back slightly and then loaded them into Helicoid software.

In-Camera focus bracketing - how difficult would it be?

I would defiantly like focus stacking built in to my camera, especially if it helps me get shots like the moth!
