You told me something I only learned recently saxplayer. Go manual on macros. I am a bit embarrassed, that is probably a basic rule. I hope you did not learn that the hard way like I did  . Thanks, it always helps to have someone confirm something you are not sure of ! As far as focus peaking I could not for the life of me figure out why my new camera had that blue haze at focus lol. I thought the camera was damaged. Our wives tell us that we don't read instructions...busted ! While I am here I ask you to revel in my victory that just happened.(Hope I remember how I did it lol) I mastered my first photo stack minutes ago using the Lumix. It is a more complex process than the one button push with the Olympus P&S camera. You basically use the touch screen to move a focus box to different distances on the subject and take photos at each distance point. Then hit the 'collate' button to blend the varying distance shots into one photo. Had I zoomed in on the forest 100' away outside the window and shot it it too would have been in better focus. Same deal with the distant whiter wall(the focus box was a bit big causing an overlap intersection of distance within the box). Anyway, we are in ok focus from .5 feet to 35 feet. Need a bit more practice and better light.  |

I think I made a mistake saxplayer. The photo stack was made from taking aprox. 5K video(3504 x 2336) at a rate of 30 frames per second for 2 seconds(60 pics total) starting at the closest point on subject to the furthest point on subject. And then merging all 60 - 3504 x 2336 frames together to make a final stacked photo of 3504 x 2336 in size. This only creates a lower resolution(3504 x 2336) stack. Here is the 2 second 5K/30fps video recorded in the Lumix. I then sent it to Youtube. And it is likely that Youtube reduced the 5K definition to something less. PS To make higher resolution stacked photos you use the other process: -You basically use the touch screen to move a focus box to different distances on the subject and take photos at each distance point. Then hit the 'collate' button to blend the varying distance shots into one photo.- |

Then hit the 'collate' button to blend the varying distance shots into one photo.- That's a pretty cool feature! I use a mechanical rail that moves for me in increments I determine - as small as 2 micro-meters  I then define the delay in 1/100th of a second how long after it moves to wait before opening the shutter and taking the picture. Pretty darn cool. I'd prefer my camera to just do it for me but.. I have to adjust to what I have ) |

I never braved the mechanical rail technique saxplayer. You must be skilled at photo software. I have watched the process on video and considered the process beyond my ability. Recent innovations in digital video imaging software are impressive. Store bought drones now have the ability to record footage thru a fisheye lense and process it to flat footage as the footage is being recorded at 4k/60 frames per second. And record the video footage and process it to maintaining the horizon as level instead of showing banked turns. These onboard video processing chips apparently get hot and require tiny onboard cooling fans. Maybe future cameras will have cooling fans  . Similar stitching technology to focus stacking and connecting multiple shots for a 360 panorama. It takes tons of processing capability to do these functions. |

Two photos. First is of a rock/fossil I found yesterday. Second is when I used macro to show the inside areas of the depressions.   |

I'm not a technical photographer. But I've worked hard to develop techniques for gem/jewelry imaging. Digital photography has been very liberating for me, providing the opportunity to experiment widely with all sorts of trial-and-error methods. This image was made with an "antique" Nikon 4500 Coolpix, still my camera of choice for most gem imaging. It's not technically a macro shot. It was made by close-focusing on one of my fire agate cabs and cropping. But the lenses of this Nikon series are excellent for general work and I'm happy with this image's color accuracy and detail. The internal world of fire agates fascinates me - one of Nature's most delicate and mysterious art works.  |

Thanks, the bee was collecting pollen in a cholla cactus flower.

Being able to see all the pollen grains is so cool. That little bee looks so cute in that picture.

Excellent photo of the beee and pollen. Thanks, one of my favorite photos. Not bad for a phone camera. |

Thanks for starting this thread, Grant! I can't wait to see the amazing pictures that will be posted here. Here are 3 of my first macros. All 3 are crazy lace. The first 2 show an area about 1/4 to 1/2 inch wide. The rock in the last picture is zoomed out much more, but the entire rock is less than an inch in any one direction.    I need to get more tumbles done so I can get more pictures! I love that last one!! |
