well i was a thinking how about a backdrop of some sort you can use to help with pics,
that way the pics are quite uniformed
so group grows the plants will be easily seen.

in a tent i usually have a few strains going so taking pics of them in full bud is quite problematic,
having some sort of material backdrop you can cover/block other plants out focusing on the main subject.
mainly for bud shots really,
helps with focusing the camera as well.

you could;d tie it on bamboo canes and put in pots or tie to tent poles,
might take out the yellowness of the hps light as well.
all have the same colour.

i am very stoned on double death so this might sound gibberish in the morning ;)

anyone who love to take photo's and wants to produce quality photo's should learn "Lightroom 5" it's an adobe product. you can do amazing things with photo's with lightroom 5

but i do agree, a good backdrop and quality lighting are important to good photo's

There's LOADS to do in Lightroom. I have a thread on Marp that I can copy over that may help people realize how powerful Lightroom 5 is, in develop mode.

Here's the link Ozzy.
