So far, I've been taking a picture every minute from 7am to 7pm using a webcam:
- the webcam is connected to a raspberry pi
- a cron job on the raspberry pi takes pictures (note: cron is a utility for scheduling tasks)
- an LED grow light turns on from 7am to 7pm; this light is controlled by a Kasa Smart WiFi plug + IFTTT
For plants such as scallions, taking a picture a minute works really well as you can see how much the plant moves and sways throughout the day. I am under the impression that my nepenthes, pings, and VFTs don't move anywhere near as much, so I'm going to try reducing the interval to one picture every 10 or 20 minutes.
Like the posters above, I also experienced issues with lighting. The grow light helps keep lighting more uniform but it adds a bit of glare. Setting up additional stationary lights as recommended by rivera sounds like a great idea. I'd imagine that, before taking a picture, the grow lights could turn of and the stationary lights could turn on.
Another issue has been focus. The webcam's autofocus tends to be a bit finicky and doesn't let me control what exactly to focus on. Using a camera with manual focus could solve this issue... I want to figure out how to use a DSLR with this setup.

I'm still trying to find a good solution for this. I've been using photoshop so far but it's too tedious. What options have you tried out?
