What is the secret of using color gel
I guess the question is how do you meter color gel to get the best colors out of them.Sample maybe with using fog etc. Dec 08 07 08:17 am Link forget gels, do it in post in CS Dec 08 07 08:24 am Link NC Artistic Images wrote: I agree...gels are so "analog." This is a digital world. I'm giving mine to good will. Dec 08 07 08:30 am Link depends on what you want to use them for. I didn't understand the reasons for using gels until I was like what the heck. But they are good for background lighting like this or just setting the mood for a photo. All on personal taste. Some can get carried away and doesn't look good. It's all in how you use it.

Dec 08 07 10:41 am Link The gist of it is that the lower the power the more saturated the color is. The higher the power is the closer to white the color will appear. This is some what counter intuitive. When you're not seeing enough of the color it's tempting to turn the light up. Resist that urge andactually turn it down. The color saturation also depends largely on the color of the background or reflective surface that the light hits. White is the worst. Stick with black or dark grey, you'll get deeper colors.

Dec 08 07 10:48 am Link NC Artistic Images wrote: LOL no comment Dec 08 07 10:48 am Link I use gels alot. Its easier than trying to add it in later in PS. I am also not a fan of making more work for myself later. Meter your lights first then add the gels. You're probaly shooting digital. So take a test shoot look at the results. You might have to turn the lights with the lighter gels, yellows, oranges and some light reds, down. WHile the one with darker colors will need to go up. Adjust take another test. In the days of film everyone had a polaroid back for their camera and would pull several "roids" before shooting actual film.

I mount a coarse grid with gel filter holder on my background lights and adjust intensity to taste. You can also use complimenting or competing colors in two separate lights and experiment that way. Just remember working gels is kinda like chroma key - you want to keep the model about 6-8 feet from the background to avoid light spill on the model. While some like ring lights, I often prefer a medium grid on a 7-10 inch reflector with various filter gels (for light skins a light amber is nice). Once I have the main, fill, hair and background lights metered in place, I place the amber gelled light within inches of camera position and at the model's nose level - she gets a nice skin tone without spill onto other elements of the scene. Yep digitially dependent, photoshop addicted shooters can achieve some of the same results in photoshop - my time is more valuable than to throw it away on post production work. I prefer doing it in camera. Dec 08 07 10:56 am Link ren and nc, i see nothing in either of your portfolios that looks remotely like it was lit using gels. how can you even consider giving that advice unless you have experience? if you do, it would greatly lend to your credibility if you showed at least one example. common sense dictates that many effects are much easier if done before the image ever gets near a computer Dec 08 07 11:41 am Link Z_Photo wrote: Remember, this is the new age, it's like explaining how to shoot film to newbies or "GWC".

Main Tip: don't overexpose them or you will lose much of your color saturation. Use a black or white background for better color (black has a deeper color... try it) Oct 07 08 11:37 am Link Ohh gells I have a project that I want to use them for to get some fun gradation in the BG. If I use a 10' grid and then make sure the color is NOT hitting my model can I get my BG to be two different colors? Oct 07 08 11:41 am Link I've been using gels more and more. I don't meter, but rather play around quite a bit until I get the effect I'm looking for (and take lots of notes while doing it). It's a lot of fun and easier to experiment with product photography (and dry ice!!) before you throw in people. Oct 07 08 11:47 am Link Forget meters..you're shooting digital. Just look at the picture. If you like it, you're done. B Oct 07 08 11:53 am Link I have gone back to shooting old school on a Blad and I am loving gels. To meter for them on a grey background I use the relective part of my light meter and try to get the reflective reading from the gelled grey back goung to read half a stop lower than what I have metered for the face. I find this usually gives me a nice rich colur in my background but it can vary between colours so either test it on a digital camera or shoot off a quick roid to check your exposure. Oct 07 08 11:57 am Link JMX Photography wrote: But that is the key. I use gels all the time in my Nor. Cal. studio. The key is to keep the gel'd lights at relatively low power. That means reducing everything else as well. You also need to develop a good eye for balance, but in the end, you will get some remarkable images. Oct 07 08 12:01 pm Link We need examples in this thread... Oct 07 08 12:02 pm Link They're kinda cool to use in hairlights too. Here's a blue jell shining down from a boom attached overhead hairlight on TraceyP... Oct 07 08 12:07 pm Link For this shot, the light was not aimed directly at the fog....it was aimed at the black background, bouncing a limited amount of light through the fog. This way, the colored light from the gel didn't hit the model. Fog was provided from the top of the background. Since it was a "low-level" fogger, the fog dropped from the top of the background without dissipating much. Oct 07 08 12:10 pm Link gels are fun. its up to your imagination to use it. if you're familiar with color darkroom it could be even more fun. Oct 07 08 12:11 pm Link like most things in photography, gels can be used for good or evil. cameras are more sensitive to the red end of the light spectrum and less to the blue end, this is why normal metering will not be consistent.

In both cases I didn't pay attention to family of angles, bounced the light off of a white background and got undesired spill onto the models and it made their hair look funny in a bad way. I paid a little more attention in this case: Paid attention to my angles and bounced the light onto a black backdrop to reduce spill. It came out exactly like I wanted it to. I metered the strobes for the model, then I dialed in the backdrop once the gel was on by chimping. It didn't take but 3 shots to reign in.

I think in this case the gels intertwine the subject and the background. Ron Oct 07 08 12:33 pm Link Use the gels to accent your image.... don't use them as your mains. Done with skill they can make an image look great. To much and you are in a rave! We paint stage wash with them all the time!
