hello i have a spotted mold
what can i use in my plants
Spam and reported.
the lines are caused (maybe?) by "IMAGE ALIASING"
or perhaps learn to use the white balance setting on a camera
this can make a huge difference to the clarity of pictures
hps can actually give some nice pics with the right settings
but i do agree in general some of the light polluted pics posted are terrible
this is mostly because of the intensity of the light not so much the type of light
and the fact folk be taking pics on their eyefone lol
Nope. They're sodium deposits you're camera picks up because it "sees" better than you.
And this seems to only really happen on my camera in the 600+ watt range, 400 don't have them on my phones camera.

the lines are caused by a shutter speed that is too low
if you raise the shutter speed the lines will vanish
some shitty cameras older and or phone cameras
do not have a shutter speed that is high enough to get rid of the lines/flicker
The lines are a simple interference pattern, caused by the number of photons hitting the sensor. Speed up your shutter and you'll get rid of it, slow it down and it'll get worse.
Thanks for the tip!
If you have a smart phone you can just click on the AWB or auto white balance and set it to Florescent and that should work
Ok so i dont have any recent pictures of my problem. but my girl is in soil about 6weeks from seed under a 250w hps in flower. she was in a 2L bottle and only the top set of fan leaves are deforming. perfect green color but they are wrinkled but not dry at all. i transplanted her to a 2gal pot thinking her roots needed some air. this picture is about from a week ago she also is very short
yes use sunglasses over the camera lense it works fine
lol how did @sunni let you have this username?!? jk you're probably right my friend on this one!
everything looks good here to me aside from the leaves should be perking up. i would reduce your water schedule.
If you want accurate pics, don't use auto-white-balance, use full-spectrum light and lots of it. Color correcting after exposure or using automatic methods is not going to help the experts here help you with your problems. I don't know much about cannabis cultivation, but I'm OK with a camera. This thread should be canonized on all forums, I get so tired of looking at pictures flooded with yellow or pink light. AWB is not going to be any more accurate, the software is making an "educated guess" as to what color is actually white. If there's no actual white in the picture, say your walls are a light lavender hue; flooded with colorful light or not, it isn't going to be a color-accurate image. If you correct the light spectrum and want to use AWB it might work, but it definitely helps if there's some actual white in the shot.
Pro tip: When taking pictures of very pale people white balance on a very pale shade of blue, just barely any color in it, but sort of a sky blue that is desaturated. It will make them look less like the undead.

Magnetic ballast pics show lines, my new digital ballast has no lines in the pictures
Lights out pics are wonderful
