For those struggling for inspiration, using your IPAD as a background is a viable option. These images sere taken of the same water drop just using different photos of the waterdrop on the screen, at an oblique angle.
Thanks. Lay the screen of the iPad facing up, find a photo on the iPad, place a water droplet using a syringe, then set up the camera, manual focus, set exposure and tak a photo with sufficient depth of field to get the majority of the drop in focus.
I am using the 90G Macro on my A7r4. But sometimes I use it on my a6300. Works just fine. if I can’t get enough depth of field, I will focus stack a number of images.
Depends on the subject and how small it is. If it is flat, very few, if it is round the stacks need to be closer together. Sometimes 5-10 is enough, other times I will do about 40-50. For these images, I used around 10 shots.
It’s about depth of field, not shutter speed. Using a tripod, you can have a shutter speed as slow as you want (depends on ambient light) f stop will dictate the depth of field, but once you go macro, the DOF may be as thin as a fraction of a millimetre. That is the reason to do focus stacking. Don’t forget that the iPad image will be providing a lot of light as well
