I've heard many photographers say that macro/close-up photography is not easy to do. I totally disagree, it's actually very easy to do if you know what you are doing.
There are just some basic things you need to know to get nice sharp all in focus images.
You don't need to focus stack; you can get it all in focus in one shot. How to avoid shooting in clutter is easy to do.
You can buy the lowest priced digital DSLR or mirrorless cameras, any macro or zoom lens and produce excellent macro images.
You can take lots of time to figure it out on your own or join my Macro Photo Club and speed up the learning process.
The club has over 280 instructional videos covering tips from the field, composition, post processing, and equipment.
