Somewhere someone posted a thread/tutorial about fixing pictures that were taken under HPS lighting. To get the orange out of them. Does anyone know if that post was on this site? I had it saved but I built a new computer and don't have it anymore. I'm not very good with Paint Shop Pro or Photoshop and would like to find that tutorial. I've figured out how to adjust the white balance on my camera now, so that I can take good pictures even under the HPS lights, but I have some older pictures that I'd like to somehow adjust to make them look better. Does anyone know where I can find that tutorial? Thank you.

Call me uneducated but i find i get my best results at night with a flash, or during the day : under natural light(lots of it). I feel as tho the second youve altered the image with filters or any kind of software plug in - in order to "make it better", is kinda cheap most definitely i would consider it cheating. The only reason id touch an image with software is to either make it smaller(size) or crop this is in regards to Cannabis/Bud pictures, what i cant understand is why anyone would go through that whole process when taking a picture at night with a flash or during the day with natural light will net you waaay wayyyy better results... my 2cents tho...
Please link that thread you referenced in your thread, i would like to see what it is youre talkin about

Thanks for the reply. I can't link the thread yet though because I can't find it. I don't remember if it was on here or on another site. As soon as I find it I'll post the link.

I remember looking for that same thread and not finding it as well. I'm pretty sure it was a different site though.

Manually setting the white balance on my camera allowed me to take out the yellow of the hps and take nice pictures. I however do not like taking pictures under the hps and usually take my plants out and use a nice daylight cfl to light the room. Using long exposure and a tripod I get decent pics.

Mash explains the hue/saturation process of removing color cast created by HPS lights

Open your image in Photoshop


Create a new Hue/Saturation adjustment layer


Click OK when presented with this dialog box


Select the Yellow color channel from the "Master" drop down box


Desaturate the Yellow color channel until satisfied


Experiment with adjusting the other color channels to your liking. You may be surprised at what you can come up with.

After a quick Mashing

Or you can go, [Enhance], [Adjust colour], [Remove Colour cast]
your cursor turns into a dropper tool, pick a part of the picture that should be white, and left click.

Thanks for the help.

although not on topic exactly some interesting effects can be obtained under HPS with another light source on the subject.

In these two shots the flash offsets the hPS.
