Stacked focus defined in this thread: forum.rocktumblinghobby.com/thread/75549/first-photo-stacked-focus?page=1&scrollTo=872908Very useful for roundish tumbles with close up shots, gets the whole rock in focus. New digitals will have this option as standard equipment. Amazing to hear camera ring off a dozen or two shutter shots in a second. then camera does calculation. You normally get two photos, one stacked and one of the not stacked frames. Results, not stacked, note back out of focus. rockpickerforever 's fine palm. stacked photo. 10 photos from front to back and the Fouriered

Another stacked photo. This time rockpickerforever's block of crazy lace. photo taken at 45 degree angle to face of rock. Hand held and intentionally shaken a bit. Not stacked, top(back) out of focus. Stacked, full focus front to rear

Camera is $349 Olympus 'Tough' TG-4. New waterproof model. Point and shoot. Higher cost probably due to waterproofing. Also has a nice 45 magnification microscope, WiFi hot spot, compass, barometer, GPS, nuclear reactor(not really)

Cool camera. Lens is fast at f2.0. Takes great low light photos w/out flash.
Zoom sucks at only 4X but that is a good thing. Big zoom causes photo distortion and causes mechanical problems. This camera does it's zoom lens extensions internally to stay waterproof and reduce chance of damage and entry of dirt.

James, that is awesome! I am assuming that you are using a tripod?
Those are amazing photos and some very high quality Crazy Lace!

Camera only 1-2 inches from rock. That stacking focus may be on many recent cameras. Crazy lace ain't bad. About the size of a half a brick.

The same idea is used in high dynamic range photography, except it's used to balance tonal range in a photo. Multiple bracketed exposures captured and combined to present an image that is closer to the kind our eyes and brain can produce. No more blown out areas or underexposed dark patches. These new cameras make good photographs darn near foolproof.

These new cameras make good photographs darn near foolproof. The camera may only be varying the focal point garage, not sure about the exposure... Darn camera rattles off 10 photos and then internally combines them garage. No computer time, camera does all calculations. Takes it about 15 seconds to brew 10 frames into one frame. Only the final product is stored on SD card, so it does not use up storage. So if subject is 30 inches in depth, it focuses every 3 inches along it's depth and takes a photo, 10 times. Then combines to one. Curious if exposure varies each photo. Stacked focus works great on the microscope mode because of the extremely short depth of field of view at high magnification. Does 240fps mean that the camera can take high speed video at a rate of 240 photos per second at frame size of 320X240 ?? Apparently it does, and then you can play it back slow-----HS 240fps*1 (320Ă—240) specs: Submenu 2 Application 1080p 720p VGA (640Ă—480) HS 120fps*1 (640Ă—480) HS 240fps*1 (320Ă—240) Select the image quality based on the image size and frame rate.

Check out the Lytro camera, jamesp. They were probably using the same process that your camera is using, but instead of stacking all images to create infinite depth of field, the Lytro produces one image that allows you to select the focal plane AFTER you've taken the 'photo'. It is probably creating one large file with multiple captures. Not sure about that, but I do know they were the first company to hit the market with 'selective focus'. Maybe still the only. Neat little camera, but I can see more use for 'infinite focus' like your Olympus.

Being lazy and sitting at desk: Normal photo: Stacked photo Cross cut and tumble polished coral, not stacked. Mostly blurred at left and most distant of macro: Stacked

Gotta love a new toy. Especially for a photography geek. (That's me, not necessarily you) Look forward to many (super sharp) pics of your numerous projects.

In the absolute geek mode lol, enjoy geek mode a lot. I did learn the burst rate is 5 frames per second at full 16M resolution. 5 fps limited by the high 16M resolution. Fast for a cheap camera. Drop to 3M resolution and it picks up to 15 fps and 60 fps. Those speeds are still baffling me. I get the higher resolution in this video:

Those are good burst rates, especially for a point and shoot. I may have to take a look at that model. I've been thinking of finding something that would hold up to some rough handling. Olympus cameras have done me well in the past. My DSLR is weather resistant, but I don't want to lug it around in the creeks with me.

Olympus cameras have done me well in the past. My DSLR is weather resistant, but I don't want to lug it around in the creeks with me. In the past 3 years the 60 fps recording, high speed sequential action, burst and stacked focus has been a new technology target coming available on about all ranges of digitals. This camera in particular was desirable due to it's rugged build and that freaky fine microscope mode and above features. I was unaware of all those features, was simply looking for a tough camera. New features opened pandora's box. Great starter camera to learn using the new stuff. DSLR ain't going into the great outdoors.

Nice camera, great idea! What will they think of next? This stuff will all be standard on new cameras Jean.

You guys are KILLING ME!!! I already spent all of my allowance on rocks and tumblers. Now I NEEEEEEED a new camera or I'll probably die (not really)!!! I need to remember an old saying I learned when golfing and admiring my buddy's new $500 driver, (and it certainly applies to rock tumbling AND photography) "It's not the arrows, it's the indian." (no racism or anything like that intended in any way) jamesp you are a rock star (pun intended) at both tumbling and photography. I bet I could give you a lump of charcoal, and it might take you six months, but you'd ultimately be able to produce a museum-quality photo of a museum-quality diamond from it. Me, on the other hand, well let's just say I leave a few things to be desired, but I'm learning!
