Wow! What app(s) did you use and could you share your process?
Sure thing!
1. Need a tripod that can hold your camera (or phone in my case).
2. For macro photos you need a macro lens. I use an expensive (but well worth it in my opinion) from Moment or the new iphone.
3. You need a wind free/vibration free place to put the gear because you will be taking many images of the subject at different focal lengths.
4. I use CameraPixels on my phone and with it I manually focus out so the first of the trichomes are just in focus.
5. I then scroll through to the other end of manual focus to see all of the image that will be in focus at the end of the next step. I want to see over the full focal length of my camera how much of the image I will capture in full focus. Hope that makes sense.
6. Set the app up to use the Focus Stacking mode and I choose around 25-50 images to take.
7. Once I press the shutter button on the app, it takes 25-50 images at different focal lengths, from one extreme to the other, and saves them to my phone.
8. I move the images to my laptop where I use HeliconFocus app to combine all images and create one with much more depth and focus than I could get with one iPhone image.
Let me know if you have any other questions!
If you use a DSLR and a macro lens, your images will be much, much more amazing. This is a more affordable way to get great images.
