Another laundry item to make it as a light tent is the Antonius laundry bag frame. It requires more work as you’ll need to sew a cover for the frame. Björn used the Sova twin bedsheet for the cover, which I think is kind of a waste as you’ll have quite a bit of material left over.
Hacking this Antonius could possibly be easier as it already comes with a bag. You’ll just need to find a way to keep the bag from crumpling. Clips? Sticks? Lots of possibilities. View more of Bjorn’s Antonius light tent.
The last one I have is from Michele who has Riaz to thank for it. While the others are good for photographing small objects, this one works great for portraits.
First remove the bottom of the Koja tent and use the material to close the “door” of the tent. Then spray the insides with glue and affix mylar foil inside the tent. Sew on some bits of velcro to the four sides of the tent to hold the shower curtain liner, trimmed to size, in place as the diffuser.
