I am a mom with a camera who has been asked to help with my children's school pictures. I have a 70d and sigma 17-50 2.8 and canon 85 1.8. Their end of the year program is coming up. Would these two lenses be enough to capture good pictures of moving children on stage? How do I deal with lighting? These pictures are going to be used in their yearbook. This is my first function. Any suggestions? Thank you!
Hi, Ellie. I used to teach this stuff to yearbook photographers and to pros working for a national photography company that supported its own and other yearbook printers, so this is right up my alley.
This equipment is a very good combination for this sort of work. I've used a lot less with really good results. It's your technique and skill that are most important here.
Stage lighting runs the gamut from fabulous to terrible. School auditoriums usually have terrible lighting. It's not that it's dim (it often is), but it's harsh, uneven, and contrasty! That makes it difficult to get a correct reading, especially if the stage floor is black, the curtains are black, and there are other dark parts of scenes.
Flash is completely out of the question. It is almost ALWAYS forbidden in such situations. Unless you had a professional monolight with at least 400 w/s of power, you would not get great results, anyway.
So, you are stuck with high ISO (1600 to 3200) and f/2.8 on the Sigma, and I'd use the 85 at f/2.8 to f/4 for depth of field. Your shutter should be at least 1/125 for two reasons — to avoid shaking the camera when the 85mm lens is mounted, and to stop the little critters on the stage.
The quandary of the situation is: "How do I meter this nightmare photographic scenario?"
The answer is complicated.
If the lighting is very, very even (overhead fluorescent fixtures, lots of stage floods, etc.), and the scene is of average reflectance (no predominant white or black areas), I would probably use Aperture priority and matrix metering.
In the more likely scenario that the lighting is very uneven, harsh, contrasty, and the scene has lots of spotlit figures against a dark background, I would take a very different approach. I would set the camera on full manual exposure. (Manual ISO, Manual Aperture, Manual Shutter Speed) I would meter an exposure target (Delta-1 gray card or One Shot Digital Calibration Target) at several points on the stage, in the exact lighting they're going to use (WAY ahead of the show, in consultation with the lighting control operator). I would note those readings on a hand-drawn map of the stage.
I would record ONLY raw images for such an event, and post-process them in either Adobe Lightroom or Affinity Photo or Canon DPP. You need all the exposure latitude that you can get. JPEGs have MAYBE +1/3, -2/3 stop of latitude before adjustments look poor. Raw files can be tweaked +2 to -1.67 stops — a HUGE difference.
If I thought I could get away with spot metering in the camera, I'd try it, but... I am not a fan of spot meters.
CHIMP your images (review them on the LCD) and pay attention to what the histogram is doing. Adjust exposure to keep the highlights just to the left side of the graph.
Try NOT to work from the back of an auditorium, or you'll not be close enough. With those lenses, I'd want to be on the front row or the sides near the front. I would also want to move around, so I'd wear rubber soled, soft shoes, and muted, dark colors (so as NOT to be noticed).
Make a lot of exposures. Remember the photojournalist's and the filmmaker's habit: Vary the perspective from long view, to medium view, to close-up, to bird's eye view, to worm's eye view...
Yearbook photojournalism is all about MOMENTS. You want to capture the peak expressions, peak actions, and peak emotions of the day. To do that, you have to learn to anticipate what's going to happen, and be ready to calmly press the shutter button almost before those peaks occur. Sometimes, a high frame rate is the only way to do that, but with practice, single-shot mode works well.
Finally, don't frame too loosely or too tightly. I always liked to give my editor two or three cropping options to fit the scene to a layout. That is more important for a custom high school book than a K-8 book using pre-designed layouts, because large high schools with professional journalism teachers and yearbook advisors who want their books judged in competitions are very finicky about photos they use.
