Another stacking attempt

[bugmeister]

ok, so how do you make sure you get the far edge in focus on something like this. Even though I thought I had a frame with the back edge of the coin nice and sharp, it still didn't work.

 

 

Tried again with my dessert but I don't think this is the right subject somehow.

All suggestions would be most welcome. I am determined to get something at least halfway right before I try it on bugs, even if I can find a stationary one

Hi Bugs,

 

You could put something just behind the coin to focus on, say like a screw standing vertically on its head, then remove it for the shot with the camera set at that distance, or if not focus on the rear of the subject then focus a little further behind it to start your images. With stacking you should start and finish your series of shots slightly in front of the front of the object and slightly behind the rear, not at the exact focus point of the front and rear. Its always easier with a focusing slide however as you can note the markings for the objects far and near points and just go beyond them.  

 

In this video he was using a high ISO for the video, obviously for the best quality for stills you would use the lowest ISO on the camera if possible and either bright lighting or flash.
