I do manual shots on a microscope, since I cannot drive the focussing. The stacks come out fine, be sure to make each step small enough that the focussed areas overlap.

Suddenly stopped focussing

I am using a Nikon D5300 105mm Macro lens connected to a MacBook Pro. Two days ago everything was working fine. Since then no new software or hardware has been added and the physical connections are unchanged. This morning, when I try a Focus stack, I get the following problem. I can use the focussi...

Rainbow scarab

I found this outside the kitchen yesterday. I had no idea such beetles even lived in Connecticut

Edit: I do not seem to be able to show the image. I go to Upload Attachment, Choose then Add the file, but nothing shows up.

Manual focussing

I am using a Nikon D5300, which loses all focussing and aperture control without a lens. I have used the 'show focussed' tool to manually change focus and create stacks with some success, though I am never certain if I have managed to get every layer included

Re: Best stacking method for protozoa

Thanks: interestingly each of the three methods is better in some parts of the image than others. However, Method C does seem to be the overall winner.

DOF lens correction factor

Is this unique for each lens, or would all lenses of the same type use the same correction factor? So, if I have a Nikon 105 macro lens, would all of them be the same? If yes, then maybe we could set up a list of the correction factor for most of the common lenses as a service to other users.

Best stacking method for protozoa

I am photography protozoa, which are basically transparent, and the resultant stacks are not as clear as I would like. Do any of you have experience with this, and do you haste any advice?

Many thanks

Re: Autofocus doesn't

Thanks. At least I won't spend the next week figuring out what I was doing wrong.

Autofocus doesn't

While I normally use Stackshot, I decided to try focus stacking, to compare the results. After setting up, I click choose Autofocus, then click on the nearest point on the screen image. The camera briefly focusses on the chosen spot, then goes completely out of focus. Maybe I am missing a key step, ...

Re: Only one picture saved per stack

Okay: dumb mistake on my part. I renamed the folder and forgot to add a 'Counter' tag.

Only one picture saved per stack

I am using Remote with a Nikon D5300 and have designated that all pictures be downloaded to the computer and which folder to use. After the session is over only one picture is in the folder, the rest of the stack is not there, neither is it on the camera. Everything worked fine a week ago: I suspect...

Distance moved on stackshot

Not really a problem, just an inquiry. When shooting an object that is about 1cm deep, in order to focus on the top and then the bottom the camera moves almost the entire length of the rail (a lot more than 1 cm). I would have thought the two distances would be the same; maybe my understanding of th...

Is there a simple way to ensure that this is the case, other than eyeballing it?
