Balancing for fluorescent lights is harder than say tungsten. The reason for this is that tungsten bulbs produce the same sort of spectrum (set of intensities at different wavelengths) as a daylight balanced flash, just shifted. A fluorescent light doesn't have the same bell curve shaped spectrum, it produces a set of spikes at very particular frequencies. ...


The question that you are asking is a very common one, but the answers are not as straight forward as you may think. How does a professional make the colors so bright, the contrast so well defined, the focus so perfect, etc ? Well, it isn't just one thing, ever. It isn't a single setting on the camera, or a single post processing technique or button. It is a ...


I think in this case, a diagram or two is probably the easiest way to get the point across. A typical "cool white" fluorescent bulb produces an output spectrum something like this: In this diagram, blue is to the left, green in the middle, and red to the right. As other answers have already pointed out, your eye/brain can/will adjust so you usually see ...


I use in my studio separate lights for the greenscreen and the subject, the right way to do this is to have a uniformly lit greenscreen and no shadow of the subject on the greenscreen. You can find more on youtube from the video guys, almost same rules apply to all. More info: ...


The key words in your question are "to my eye". The human vision system is fiendishly good at adjusting white balance. Fluorescents are anything but white, but your eyes perceive them as white nonetheless. If you look at some nighttime photos of a cityscape or a building exterior, photos with a lot of different light-sources visible, you will see that most ...


This is really a technical comment to accompany Matt's answer, not intended as a complete answer - others do that well enough already. Matt did a nice job of colour correcting the firelight scene :-) ! A look at the luminance and RGB information of the original show a very sorry looking light mix which he has redeemed very nicely. The orange lit street ...


With a big green background it'll be reflecting the light and potentially messing with the color cast of the light on the subject. You'll definitely want to either set a custom white balance in-camera or use a gray card and set the white-balance in post (be sure to shoot RAW).


Then again, in some countries, especially in the semi tropics, colors are very green. Depending upon the camera, you can also use settings which enhance colors. Like in the Nikon you can set color to Landscape or Vivid, etc.


To make your colours not only green to be bright, your photo firstly should be taken with proper exposure and secondly, you should use "Vibrancy" slider (not Saturation slider) in PS to add richness to the colour. As for the photos you put as example, third one is an HDR shot and this is a completely different type of post processing which usually takes 3-5 ...


I doubt the first picture used much post-processing at all (you could always try asking the photographer, of course...). One way to get a little more saturation in your pictures is to slightly underexpose them. The first picture you linked is a 3-second exposure to get the flowing water effect (at f/13 and 400 ISO, an ND filter was probably used), and ...


Last two images are HDR images; this technique produces overly saturated colors. As for the original question: To boost saturation of green colors simply play around with saturation in your favorite editing software. Try accessing individual color channels and adjusting saturation to your likings. If you shoot in RAW and use Photoshop, play around with ...
