For those who observe small features up close and where it’s customary to carry a wallet, maybe a wallet sized ruler for sense of scale? It also helps with autofocus issues too.
It may not be a gift for the iNatter themselves, but I found a good gift for someone you want to share your iNatting photos with: a wi-fi picture frame. I have a friend that I share pictures of all my adventures with. I used to just email or text pictures, but that wasn’t exactly the most convenient thing (half the photos didn’t go through on text, she doesn’t check her email very often, and she doesn’t do social media). I got her a wi-fi picture frame this year. It comes with an app that lets me upload the pictures or short videos directly to the frame. She can also set up slideshows with her favorite pictures and set them to music, and she can use an SD card to copy anything she wants to her computer. I’ve sent her a few pictures already and she seems to really love it.
I got a gorgeous 3D printed coral polyp using a thermo-sensitive material that changes color when warmer (to simulate bleaching).
The 3D files are available here: https://coralreef.noaa.gov/education/polypmodel.html
The polyp also does ok at hiding jewels, holding pens or even a cup.
