Ok, so I realize that it's like a baby step, but I've got a big shoot for little money coming up.
I'm thinking of it as a test bed for learning more about the craft... I don't get a lot of opportunities and I have nobody else to take pictures of, so it's a good thing... I consider myself quite to be VERY green with this.
I will be taking pictures of a rather elaborate 'graduation' show for a local kindergarten... before you guffaw and snicker, these things are usually more elaborate than the entire set of proceedings of my sister's High School (gr. 12) graduation back in Canada a few years ago... and that was a pretty big deal... There will be two primary sections, one with certificates handed out, along with awards, and another section with performances of song and dance.
This is actually the smaller of two events (one of which takes place in the Penthouse conference room in the Grand Hotel, one of the top 5 swankiest hotels in Taiwan), and if I do well, I might get lucky enough to get called up next year for the big one...
Anyhow, my questions involve camera settings.... I want to hear some suggestions on low light shooting... Particularly on the 'exposure vs movement' equation.
I will be using my 30D plus 50mm f/1.8 for probably 90% of the shooting.
I have been asked not to use flash, although this is likely more specific to shooting the performances rather than the handing out of certificates as there is often a gaggle of parents at the front flashing away with their little pocket cams.
I may be able to borrow a Canon 380EX from a friend.
I am looking for a goal of 1/80 in shutter speed, and am willing to shoot up to around ISO 1000 or 1250. I will shoot in RAW. I hope to be able to stop down to around f/2.2 or f/2.0, but I am not afraid to shoot at f/1.8 in a pinch. Ideally, I would love to shoot around f/4.0 to 5.6, but I'm pretty sure that the lighting will NOT cut it.
The lighting will probably be stage lighting, fairly well handled, but with use of lots of colored spots.
I will probably shoot with AWB in RAW...
I will check my exposure with the Histogram.
Feel free to comment on whatever you like, but I have these specific questions...
#1 Would it be wise to shoot with the exposure in the middle of the histogram, or can I let it go a bit below low to prevent too much motion blur? I realize that I can push it a bit in RAW, but I'm not holding my breath on quality there.
#2 If I find that I need to get more light, where would be the best place to get it from? Shutter speed, Aperture or ISO? (based on the above statistics of a starting point of 1/80, f/2.2, ISO 1000)
#3 Regarding AWB, I realize that it's ok because I can readjust in RAW later, but because I expect to be shooting in the neighborhood of 500+ pictures, and I don't yet know the deadline for having them ready, I wonder if it might be wise to use tungsten or something (if I recall from another time I attended the show, the lighting is VERY orange) to minimize the corrections done later?
Post processing will be done with Canon Photo Professional, then PS 7, and I believe I will probably need to hit it with a bit of NI in PS.
#4 Would I be wise to use drive mode? I only have a single 4GB CF card and a 1GB backup. I will be bringing a HD which might take as much as 30 minutes to strip my 4GB card... I may get a faster enclosure though in the meantime which could pull the whole thing in 15-20 minutes.
#5 Would it be better to shoot handheld or tripod mount with a loose ballhead for stability?
Thanks for the opinions and suggestions! |

First of two bumps.
Why two? Probably because of crayon's thread.... ;) |

I'm no expert, but I just did a theatre production shoot, so working with stage lighting is fresh in my mind.
#1 You should be able to take your subjects a bit below center of the histogram without suffering quality, but in the heat of the game you may not realize that some of the kids ended up too dark. I.e., if you aim for below center, you have no safety buffer to recover the occasional really underexposed shot.
#2 Looks like you are up against the limit on all three. In particular, if you are taking group shots, then I doubt you can go below f2.2 on the 50mm lens and get the whole group in focus. For individual kids, you can go all the way down to f1.8, just make double sure to focus on the eyes.
#3 You definitely want to get the best white balance in camera, since it affects the dynamic range of the raw image. If you know the lighting isn't going to change, then use custom white balance measured off a gray card before the show. If lights are very orange (as stage lights can be) then the card really has to be gray, its impossible to measure saturated colors on a white surface.
#4 If the kids are just standing around then single shot mode is probably fine. If they are very animated then drive bursts may help you catch that priceless expression.
#5 I'd go with handheld if your shutter speed doesn't go below 1/90. But then again I find tripods a huge pain. If you're used to yours then go with it and buy yourself slower shutter speeds whenever you can (when you are far away or your subject is really still) |

Do you shoot in RAW often; be careful watching your CF cards fill up. You can push it if you want, you'll have almost two stops either way in RAW without losing anything.

Your shutter speed an aperture have to work together. You shouldn't adjust the aperture without adjusting the shutter speed, and you aren't going to be able to do one without the other (and make a difference) unless you are killing your image.
The first thing to do is lower your aperture which will raise your shutter speed. If you are at your maximum aperture then you need to start kicking up the ISO.

RAW doesn't use the white balance setting anyway, it's RAW. You are going to use your converter to do the white balance so don't worry about it, put it on AWB.
You can use bridge to convert all your images at once anyway, so there is no factor of "corrections done later"
I'm more worried about your CF card capacity if you are looking to shoot 500 pictures.

Why don't you just start out in PS? Does your canon program have the raw converter? You should get the upgrade to CS2...the new version of Bridge is worth it alone.

yes, bring a drive.

I would get a monopod.

Thanks again for the suggestions.
Magnus. I will keep in mind 1/90 as a target... I still don't really know what the lighting will be like... Because they will be changing the lighting a LOT during the proceedings, I imagine that this will get VERY hairy. I will probably start in manual, but then end up in Av mode.
I was of the impression that white balance is still just an adjustment in-camera, whereas a RAW file is unadjusted. I just wasn't sure if perhaps there might be some benefit to pre-setting the white balance.
If I remember from last year's show, they used a lot of colored spot lights...
I am considering using the 5 fps burst mode and trying to shoot 3 pics each of the kids as they get their certificates (probably around 50-60 kids) and then try to get 2-3 of each of the rest of the kids in their performances (probably around 100 kids). Tracking who I have shot is going to be DIFFICULT as there are also quite a number of costume changes.
I will try to do some RAW shooting before the event, but as I mentioned, I am fairly new at this DSLR thing, so it's pretty new to me.
RAW files are 8.7MB each... that means that my 4GB card should be able to handle a little over 400 shots. I have a 1GB as backup. I don't know how long it will take to pull 4GB to another media.
So your recommendation is to get exposure first from aperture, then from ISO, and last from shutter speed... ok, I was kinda thinking that myself... I am pretty sure that if you adjust your shutter speed, then adjust the aperture the other way, this will not actually get you more light.
I will use the Canon software because I understand it has some pretty decent RAW conversion abilities. I would use CS2, but I think my sysem would have a tough time with it... I am considering increasing my RAM before the shoot, but I don't think it will be enough.
Also, where would I get the money to upgrade to CS2? It's not exactly cheap.
I will have a look at the Monopod suggestion. It's already been tagging my brain as a highly useful appliance... I tend to switch orientations a lot, so that might be a little clunky. Again, more money... I will probably end up shooting without one... Although I may bring my tripod and tie the legs together to mimic one... Not entirely sure yet.
thanks again all! |

Kieran, I may be really off on making this suggestion (I hope if I am, someone will point out to me why!), but, to deal with the possibility of running out of space on your CF cards, how about starting with the 1GB card instead of the 4GB? Then when that one fills up, continue with your 4GB while your 1GB gets dumped to your HD. That way, by the time your 4GB card fills up, your 1GB should be ready again, since it should be a much quicker copy to the HD than your 4GB would be.
Does this make sense?

thanks. It's a good idea.
Actually the thought had occured to me and it's likely that I will do this... I am a bit concerned because the card is a bit older and the speed is only 1/3 that of my bigger card... It's possible that I will be able to do test shots with it though... |

fwiw, i have very little experience with an event like this. however, i DO shoot a good number of concerts (using a combination of flash and no flash). if it were up to me, i'd take the shallower DoF that 1.8 gives over the noise created in a higher ISO file. noise/grain is fun when shooting action (like bands), but i'd think you'd want your shots to be as clean as possible with this.
i dunno about the monopod (never used one), but i definitely would not use the tripod. those kids are going to move around way faster than your ballhead will.
in any event, it's a good opportunity. good luck! |

Thanks muck!
I am also thinking about possibly bringing a mini tripod for some blurred action shots with my borrowed kit lens at wide angle... Might not go there though... |

Just had another thought, Kieran. Do you think you could "predict" when in the event your CF card will run out if you start with the 1GB (or the 4GB)? That might help you to determine which to start first with, too. You wouldn't want to run out when a lot is going on, especially considering how many shots you plan on getting of each kid.
I guess the most important thing is to not run out while they're getting their certificates, because you might miss a kid or two while you are changing cards... Maybe temporarily switch out to the empty card right before this segment of the event happens? Just something that popped into my head, and I'm sure you've thought about it already, but just in case...
BTW - congrats on getting this opportunity, and Good Luck!

Well, that's done the first bit...
Quite exhausting really, being on alert for a full 5 hours of heavy shooting...
I took around 600+ RAW images... I could have EASILY done 10 times that, but I've only got the one 4GB card right now... It's scaring me that there exists the possibility that for a 5 hour shoot like this, I could have filled up a 60GB HD... The way I was shooting (3 images at a time, I probably would have gone all the way to 5000 or 6000... I ended up hesitating a LOT and switching to a slower FPS rate after my first 250 shots went down VERY quickly)... If I had shot more conservatively, it would have been around 2000 shots... Probably reasonable... I would probably have burned right through my second battery... My first battery didn't even lose a bar...
For GentleSoul - I shot all but the last 8 images on the 1GB, then threw it in the HD to rip (it's an older device, so it takes close to 30 minutes per GB... time to UPGRADE), while that was going, I shot the 4GB... When I got down to 100 images left in the 4GB, I ran back and grabbed the 1GB... I shot 100 more images on the 1GB and (as it was nearing the end of the show at that point, I didn't want to miss anything) switched back to shoot the last 100 on my 4GB. I could probably have loaded the 1GB at that point into the HD and been ready to go with another 100 images...
I reviewed my histograms several times (especially near the beginning of the shoot) and it seems that most of the images were pretty evenly exposed... A little better than it could have been if you ask me...
I brought a grey card with me and used the custom white balance.. I'd really like to know a bit more about how custom white balance works... It seems to have had some effect on my RAW pics, and it seems to have carried over from card to card, even if the original grey card image was no longer there... Something to play with... That grey card appears to be worth it's weight in gold... I got a 4x5 card, and two 8x10 cards in the pack... I think I'm going to cut up one of the 8x10's as they don't appear to be really useful for much. My friend could definitely use a card for himself...
I had several different types of lighting, so when things lulled, I pulled out the grey card and shot blanks as reference points for WB correction in RAW for later... Might save me some time... Might not...
I discovered part-way through my preparation that my 50mm f/1.8 SUCKS wide open... Ok, maybe it's just me and I haven't actually had a look at them on the computer yet, but they looked soft as hell...
So I ended up starting the show at 1/80, f/2.5 ISO 800. I got lucky and the lighting really improved, so this was too bright! Excellent! I stopped down to f/3.2 and punched up the shutter speed to 1/125, with an ISO of 1250, which is where I did most of my shooting... There were a few bits where I got away with f/4.5...
I was so disappointed with the results that I decided to give my 80-200 a whirl, and it worked great... My biggest problem there was that my angle of coverage sucked as I kept wanting to be right in the middle of the audience to get the angle I wanted... Next time, 16-50 or 17-50mm lens... Without a doubt... I almost got one before the show, but I didn't want to be rushed into buying a lens until I have the information to choose between them adequately...
I found the 80-200 to be sharper than the 50mm f/1.8 at f/2.8 and comparable at f/3.2. Pretty crazy considering that I was shooting handheld at a variety of focal lengths including full telephoto, and doing so at 1/160.
I ended up switching back because of range...
Thanks again for all the advice...
SpecialK, I will probably pick up CS2 this weekend. I did end up taking a tripod, but bound the legs together, with the height preset so I could use it as a monopod if I found I needed it...
The kids were indeed too fast though... I was barely fast enough handholding... I missed a TON of shots..
Amazing the percentage of shots with BLINKing..
Magnus, I used 1/80 as my whetstone to get started and it turned out really well...
I will try to post some shots later on... My biggest worry is that after taking all those pics, I won't get any that turn out! :) Not to mention PP time on all of those pics... Even sorting them is scary...
Incidentally, I did miss a few kids as they were handing out certificates... Most of them didn't even wait, they were already bowing (and closing their eyes) before they were handed the certificate... She was doing one kid in 2-3 seconds, almost walking the line... I tried to keep the same position relative to her, but the stage was curved and cluttered with microphone stands and other crap, so I had to duck around and recompose/focus... really irritating.
I hope I didn't miss any! |
