Poor color at receptions
 
I've noticed on an awful lot my competitors websites, footage from the reception tends to cast an orange skin tone on the subjects when using HD cameras. Is this to be expected when using these cameras or is this just a case of lazy videographers who choose not to properly set their white balance and exposure level. If you aren't using reception lighting, but the house lights are up, can one expect good color if camera levels are properly set?

This seems to be way to common and makes me wonder why anyone would except this in such expensive cameras.

Matthew Craggs February 5th, 2010 11:33 AM

I would argue poor white balance, simply because I have shot more than my fair share of dark receptions and can speak from experience that accurate colors are very doable. Thus, the equipment factor is ruled out.

I think the key is to constantly keep checking your white balance. I have edited tapes from other shooters where everything was nice and balanced during the grand entrance in front of the huge windows at 6pm, but as soon as the lights go down everyone looks like a pumpkin.

Setting white balance in receptions can be ambiguous at times. When mood lighting is used, white isn't white. If you attempt to set white balance under these circumstances, you can get some strange results. Imagine doing a WB on a white card under lavender light. you don't want the camera to try to make that card white. If you do try this, the people in the footage will look like they are from mars - or worse.

Another approach is to preset WB to indoor tungsten and then tweak the WB and CC in post to give it a more natural look. But if the lighting for the reception is lavender, you can't or shouldn't try to make it white. You can also use your own lighting to make people in the foreground who are the subjects of your shots look more natural. This can help you deal with lavender (or other color) skin but you shouldn't try to "correct" the room so that the lavender or other lighting looks white.

Travis Cossel February 5th, 2010 01:05 PM

Tom, I know exactly what you're talking about. Here's the thing. When the lights are dimmed the color temperature of the lighting changes also. So if you're using an 'indoor' preset for white balance it may no longer look quite right because the temp of the lighting is no longer standard indoor temperature. Instead, the lighting is much warmer, so you get those orange and red tones.

In some ways it DOES accurately reflect the scene you are filming though. When the lights are dimmed the image you see with your eyes has changed too, so it makes perfect sense that the camera is seeing something different as well. The difference is that the camera has a harder time reproducing an accurate image as the amount of light drops. Our eyes work much better.

Our approach is to continue filming with the indoor preset (since sometimes you'll have the lighting change or the DJ lights might also come into play). We then make adjustments in post to achieve a look that is more accurate for each scene.

I completely agree. If you try to chase white balance in these situations, you can wind up with a real mess on your hands. You don't want the camera to try to make things white that aren't. It's important to strive for good exposure. This will assure the maximum latitude in making corrections in post. If your footage is too dark of light, you ability to make changes is greatly reduced. You can't change something that isn't there.

Matthew Craggs February 5th, 2010 03:04 PM

Everyone has their own method, and I don't consider my way better than anybody else, but for what it's worth I dial in the white balance using the degrees kelvin and can adjust in a few seconds. I have never come into a problem this way, and it is wonderful to have control that precise. I find balancing off something white can sometimes require a couple of tries, and even if I have been a touch off with the manual control, I have never been far off.

Bill Vincent February 5th, 2010 08:54 PM

Low incandescent (which is usually what reception lighting is) will naturally cast an orange tint - it does not only through a camera lens but through ours as well - our eyes and brain compensate naturally so we don't notice as much.

I'm in agreement about not trying to chase white all night long. Just shoot with as much light as possible getting into the camera and adjust in post.

Philip Howells February 6th, 2010 06:30 AM

Tom, my regret is that most people, even people earning their living in this business, either ignore white balance or rely on the camera's auto setting.

Generally WB only requires setting once in any specific location and takes a few seconds and one piece of kit - a white plate.

What you should never do is chase white balance, even assuming you can (try doing that with three cameras in different places around a room) and even assuming you're able to log the changes - if you don't log the changes the edit will be an absolute nightmare.

Of course there are occasionally situations where the colour temperature is changing during an event (we did a reception in a white tent last summer, mainly illuminated by the sun shining on the tent behind the top table and setting as we worked!) but frankly the solution we took (and it's not perfect) is to set the white balance at the beginning and then correct in post.

In practice the difference is more noticeable in the shots including the white surface on which the sun was shining rather than the guest reaction shots in the opposite direction. This meant we could make progressive changes with scenes separated by a reaction shot. What you can't do is to change the WB in successive shots.

Jeff Kellam February 6th, 2010 03:30 PM

I think lots of people also dont understand the basics of on camera lighting. They use an on-camera LED light with a daylight range balance when most other house lights are much cooler. This just exacerbates the color differential.

Erik Andersen February 6th, 2010 04:39 PM

I'm not quite sure what it means to "chase" the white balance, perhaps someone could clarify. Color temperature progressively changes during the evening at a typical reception. The sun sets, the lights are dimmed, you turn on your lights, and the DJ turns on his lights. Usually it's quite easy to dial in the correct K value as time progresses and stay very close to an accurate white balance. I'd like to stress the importance of being very close from the start. (The tungsten preset, for instance, is never close.)

The "set it and forget it" or "just fix it in post" approach will make it impossible to come out with accurate color. Let's say you have a shot with a white tablecloth in it. In your editing program you white balance using the tablecloth. Sure enough it changes to white, but everything else is slightly off. Usually, flesh tones look completely wrong and have a reddish or magenta cast.

If you've set the correct white balance, both the tablecloth and the skin tones look correct.

So unless you plan to grade in Color or a similar program, it's worth getting used to setting the correct WB in camera. Aside from mixed lighting, the reception doesn't pose any particular challenges to getting accurate color.

I totally concur that you don't always want to make whites look white. Your real job is to represent how things actually looked, and sometimes they didn't look white to the human eye.

In most circumstances, the things you say are correct. The point that I and others were making had to do with receptions that are mood lit with colored lighting. When this is done, there is no white. In that situation, if you attempt to white balance using something that is white in regular lighting, the camera tries to make the lavender (or other color) lit white card look white but the actual result is terrible with strange results that makes a reception look like the set for Avatar II or some other surreal place.

No one is suggesting a cavalier "set it and forget it" or "just fix it in post". The specific issue is how to deal with colored lighting. In those unique situations, the most practical approach is to preset white balance around 2800 to 3200K and be careful with exposure. By having properly exposed footage, you have more room to make adjustments when you edit.

This is a very different situation than when the regular house lights are just turned up or down during the event. In that case, it is worthwhile to adjust white balance when the lighting is changed. Typically when incandescent lighting is made dimmer, its color temperature is also lowered (made warmer.) It is appropriate to adjust white balance accordingly in that situation. But that is a very different issue from colored lighting.

Philip Howells February 6th, 2010 07:55 PM

Erik, I understand your point for a single camera or fully manned shoot, but I think you're very dismissive of "just fix it in post" etc.

This is wedding video we're talking about and I think a note of reality has to apply; changing the WB on three cameras, one mounted maybe 14ft above the floor on a hot head because the DJ has changed the colour of his wash is fighting crocs when the objective was to empty the pool.

In any case, a pro should be colour grading in post.

I was trying to respond to a suggestion that you could just use the tungsten preset and be good to go. Even with actual tungsten lighting, I don't find that preset accurate at all.

A pro should definitely be color correcting in post, all the time, but if you're starting with a shot significantly off in white balance, the result won't be perfect or even close.

White balancing three cameras is no fun, to be sure. It takes time and a methodical attitude to filming. If your approach to filming a wedding is, "I need to film every single thing that happens," then you'll have to make compromises on image quality. There will not be time to get your settings right.

But I've never met a client who expects or wants to see every single second of the wedding. This means that you have many opportunities to tweak settings and plan shots in the midst of even the most hectic reception.

Think like an editor... "Okay, I've got a good shot of the two cute little kids dancing, but the white balance is not even close. So now I'm going to stop filming, correct my white balance, and get the same shot again if they're still dancing." When you do go to edit you'll thank yourself, because rather than having a 30 second shot of the same thing with poor white balance, you have a 5 second shot that looks great. That's all you need as an editor to convey what happened.

Our attitude is, "Let's capture all great moments that we can, but let's also make everything we do capture look great." There's a compromise there, but when you deliver an edited video, the "missed shots" fade from view, and the client receives a beautifully produced selection of moments from the day. In my experience, that's what they want.

I have to disagree.

If you manually set the white balance on the table cloth you're going to get the exact same result as manually tweaking it in post (assuming you were using a close preset). If setting the tablecloth to pure white in post gives you people with blue-ish faces for example, you'll get the same result by setting the tablecloth to pure white in-camera at the event. That's just how the color system works. Going with a manual WB at the event doesn't change the rules of the game.

If that system works best for you .. great! But it's not a magic fix any more than post-adjustments are a magic fix.

Erik Andersen February 6th, 2010 08:41 PM

Travis, that's not my experience at all. Let's say you are color correcting a shot, that you know was improperly white balanced. You're in a room lit with tungsten lighting, and you used the tungsten WB preset. There's a table with a white tablecloth. There are some people seated at the table. There's a centerpiece with candles. In the image, the candles appear pure white in their brightest points.

In your shot, the tablecloth is a tad yellow, so you drop your color corrector, tweak, and voila it's white. But, now the candles aren't white anymore, but are tinged blue. Skin tones do not look accurate. You haven't experienced this?

If you're prepared to sit there with each shot and play with multiple filters, you can "correct" any shot known to mankind. But while editing over 10 hours of footage? No thanks.

I'm not expert on how these filters work, but my eyes tell me that a properly white balanced shot looks awesome after a tweak in post, and an improperly white balanced one looks decent at best. Maybe I could say "good enough" but I have a hard time with those two words.

Jeff Kellam February 6th, 2010 09:15 PM

Erik:

You need to study up on color correction for your NLE.

The issues you talk about are very basic elements you should have learned for your NLEs color correction (at least in Sony Vegas Pro).

Jim Snow February 6th, 2010 09:19 PM

Erik, Travis is one of the leading videographers in the business. His work is masterful. I'm sure he never says "good enough". His voice is also the voice of a great deal of experience with weddings. A reception is fast paced and full of unexpected surprises. To do your best, your attention belongs on the things that are happening. Some of the best "catches" happen in the blink of an eye. If you're wandering around futzing with WB presets you will miss some of the spontaneous good stuff that can bring your production value up a great deal.

The problem that you mentioned with the table cloth and the candle is a typical one in post if you are using only the primary color corrector. Although very useful, the primary color corrector alone is a bit of a sledge hammer. With the secondary color corrector, you can select and adjust only one color without affecting any other color. Aside from providing latitude with color correction, it can also be used to make a selected color pop a bit.

Erik Andersen February 6th, 2010 09:28 PM

Thanks for your suggestions. Just want to clarify, I'm not trying to suggest I don't know how to deal with these issues, just that it's better to avoid them. I'm definitely not intending to suggest that Travis would say, good enough, just that in my experience color correcting in camera leads to a better result, and in less time.

I don't think preparing your camera and planning for a shot should necessarily be called "futzing." I'd rather call it "best practice."

I agree with most everything in this thread, just wanted to add some thoughts. It seems like a lot of what I've put in my posts hasn't been read, as the same points I've made are being repeated as if to contradict some of my other points. I know how to color correct any shot, like everyone on this forum, but I'd rather not have to go to extreme lengths to rescue footage, especially since in camera WB is better IMO.

Chris Harding February 7th, 2010 03:28 AM

Hi Erik

I use tablecoths on a regular basis!! BUT with auto-white balance!! The HMC Panasonics have a rather good white balance in auto as long as you are within the WB range and I find that the results are way more consistent than using any presets or trying to do manuals while things are hapenning in quick sucession!! With my cams if the cast goes orange as it probably will with the venue's incandesant lighting, I simply move the camera close to a well lit white tablecloth or even the brides gown if it's white and the Auto WB corrects it within 20 seconds ...much easier than trying to correct casts in post!!

Glen Elliott February 8th, 2010 08:48 AM

I never do manual white balancing on my cameras ever. I stopped that almost 2 years ago- I always use Kelvin to set the white balance. That way my cameras will match better.

In terms of reception shooting- dimmed incandescent lights can indeed be EXTREMELY warm. I turn the the Kelvin down as low as I can to cool the image- however this often still isn't enough. The key is to use your own supplemental lighting to get some normal skin tone back.

90% of reception venues will have less than ideal lighting which can lead to bad exposures and very warm white balance. It's critical to both know your camera inside and out and know how to utilize your own lighting- always off-camera, of course.

Philip Howells February 8th, 2010 09:17 AM

Glen, on the basis that you can teach an old dog new tricks, please enlighten me. Do you have some sort of meter which reads back colour temperature in degrees K? Perhaps I need to look at my old Sekonic L45 Studio meter and see if that is calibrated in K.

Ken Diewert February 8th, 2010 09:27 AM

I shoot far more real estate jobs than wedding work but for both I'll dial in the WB on the Kelvin scale on either the 5d2 or my XLh1. Especially in real estate the lighting is so mixed, that you set WB on one thing and 5 feet away the color temp is very different. I've always just used my eye. Sometimes I have to tweak it in post, but I find it the best way to get the most reliable WB.

Please understand I'm not stating that manual WB is a bad thing, and if it works for you then that's cool. We just don't find it practical to constantly have to set the WB manually for each scene at a reception. For one thing, we're filming with 2-3 cameras at any given time. For another, there's so much going on at a reception that we really just don't want to mess with setting WB manually all the time (especially with unexpected schedule changes, events that are started early, events that we were not informed of, etc.).

As long as all of our cameras are set to the same preset and that preset is close to correct, we actually find it much easier to make adjustments in post (with a single filter by the way - not multiple filters). We don't have to 'sit there and play with each shot' either. Once you get a shot corrected you can just copy and paste the filter to other shots (5 second procedure) .. or if it's all part of the same clip you don't even have to do that.

Again, if manual WB setting works best for your style of shooting, then go with it. We just prefer to use a preset and then make adjustments in post. And once again, if a color adjustment in post to make a tablecloth white is going to make the candles bluish, then the exact same thing is going to happen if you manual WB at the event. That's just how color works. It's not like it works differently in the camera versus your editor. d;-)

Peter Ralph February 8th, 2010 01:36 PM

it is possible that the skin tones were portrayed accurately - reception lighting is often warm.

It is also possible that the editor/colorist liked the warmer skin tones - many people do. That's why they sell warm cards.

Silas Barker February 10th, 2010 04:46 PM

IS it possible to get good colors with just on board lighting?
 
Just wondering if as far as white balancing if the onboard lighting helps, and it also seems like for trying to adjust 3 cameras white balance's on the fly is a bit crazy.

Thoughts?

Jim Snow February 10th, 2010 05:26 PM

On camera lighting at a reception that is dimly lit or has colored mood lighting can give a more natural look to subjects in the foreground while preserving the look of the room coloring in the background although the difference in lighting levels can be an exposure challenge. The dynamic range in some of the older ENG SD cameras did a great job with this. I have a friend who has a Sony DSR-390 that does a great job in lighting "challenged" receptions. Too bad HD is pushing it aside.

I totally agree with this (as if I'm the gospel). I got sick and tired of lighting problems at receptions and prayed to the Frezzi god, and out popped two dimable on camera lights. Now I just use my lighting to adjust my color. So my key is to have enough lighting to fix color easier. Quite often at receptions, we will go from room to room i.e. light source to different light source and if you stop for 10 secs to change the WB manually, you will miss shots.

One of the first things I learned many many years ago was to always WB under the conditions you would be shooting in, so if you use an on-board light then WB with it on.
I don't chase the WB most times-I WB at the beginning of the reception on a white table cloth, usuaully the cake table, using my on board light, set it and forget it unless there's something really strange going on with the "mood lighting" after they turn the lights down for dancing. In this area, the room lighing is generally "up" for introductions and toasts then turned down for dancing. SOmetimes strange things go on then but for the most part it simply gets darker with some spotlighting and special effect lighting from the DJ which is part of the "mood", my WB stays the same. I look to cover the event as it was and if the lighing makes 'em look like little green people, who am I to change it? That's what it was at the event so that's what it is on the video.

Jason Robinson February 10th, 2010 06:24 PM

I have a WB card I keep with me and I manually WB every single shot. I habitually throw up the card and re-fix the balance any time I point in different directions. Facing away from windows, towards windows.... all that changes the color temp of the scene. My goal is to get as flat and even of color balance as possible. Then I can do less work in post with screwing around with the balance from shot to shot.
