Please forgive such a beginner’s question, but I have tried searching everywhere for an answer and not found a definitive answer. Perhaps it’s too obvious a question..

I have a 2-way focusing rail and my Canon 70D camera. I wish to take a series of photos, indoors, of an inanimate small object, for instance a button or a leaf.

I set my camera on a tripod and using live view I focus on the point nearest the camera and take a picture.

Then what...
Do I use the rail to move the camera in a very small increment nearer the object AND AT THE SAME TIME re-focus on a point SLIGHTLY further back from the initial shot for my next picture?

OR

Do I not alter the camera focus from it’s previous focus setting in any way but merely use the rail to move the camera forward?

It’s this aspect that I’m stuck on; whether I have to refocus on a further back point once I’ve repositioned the camera via the rail.

A bit of warm weather so I went to hunt for insects in the woods. I found a few and then I found this Grub with what appeared to be a large horn growing out of its head. I pulled on it but it would not come loose and when I examined it under magnification it appears to be some type of fungus....or something.

If anyone has an idea of what this may be, I'd truly like to know. Strangest thing I've yet to see.

This is an experiment in using colored a background for staged macro photography. I used my Stink Bug as a model focusing on its proboscis.

I purchased a pack of recycled colored paper ($1.50 for 50-sheets) and put a small piece of the magenta paper closely behind it as shown in the attached photo using a third-hand tool to hold both the specimen and the paper background. I pulled the specimen out from under the light diffuser for illustration. When shooting the specimen it is moved under the translucent diffuser which is made from three stacked drink cups cut down to size (I have various lengths for different size subjects and lens focal lengths).

I've also included a photo of the camera rig and the subject positioner setup used for this image.

Thanks in advance to those who view and comments, suggestions and critique are highly appreciated.

Hello;
About a year (or more?) ago, I was asking questions on this site seeking help in making a setting on my Canon 70D camera where I could leave the camera at, and get reliable consistant and (sometimes) good images. The major problems I was having seemed to be with my ISO settings, and the auto focus.. (I am not of the "computer age" and not too computer or digital savvy...
One of the other UHH members was kind enough to show me a system where I could set the ISO to "Auto" and the other settings to various places. The system setup has worked GREAT for me, however last weekend I lent my camera to a family memeber at an event and she CHANGED every setting on the samera and now I don't remember the settings that I had it to. Her image results were mixed with some being amost totally black (it was an indoor event,) and a lot were out of focus although she did have it on "auto focus." Worse still, I'm on medications with a side effect of short term memory loss, and try as I may, I cannot remember the name of the gentleman kind enough to help me set up the system that I have been using the last few years; so that I can put the settings back to where they were. Can anyone help? Thanks.
