How do I take a group picture at noon and the group will be facing the sun, because of the background they want them taken at. I could use some advice on how to set me camera for this. For lenses I have 70- 200mm , & 28-300mm & my camer is a Nikon d750. Thanks a head of time for any help .
Remember the Sunny 16 rule. If you aren’t familiar with that, then read on …
In a nutshell, the Sunny 16 rule is a simple method of establishing a correct exposure when taking pictures outdoors without using a light meter. The premise of the Sunny 16 rule is that sunshine is a constant source of illumination, which depending on a short list of variables, is easy to classify. You have clear, sunny skies, hazy days, slight overcast, heavy overcast and precipitation in the form of snow, sleet or rain. Add to the above parameters the reflective nature of the surroundings, i.e. city/suburban streets, the beach, snowscapes and high/low altitudes.
The starting point for establishing the correct exposure is to set the only non-variable part of the equation, specifically the f-stop of the lens, which as you might guess when talking about the Sunny 16 Rule, is f/16.
Once the lens is set to f/16, we now have to establish the correct shutter speed, which on a clear sunny day should correspond to your working ISO speed. What this means is if you’re shooting a landscape or a portrait of your cocker spaniel, for that matter, on a sunny day with your camera’s ISO set to 100, the correct exposure should be f/16 @ 1/100-second. Similarly, if your ISO is 400 or 4000, the shutter speed should be 1/400- or 1/4000-second respectively. Easy… no?
The thinking part comes into play when it’s not a bright, sunny day, and here too we’re not talking rocket science. If you’re shooting on a hazy day, open up a half stop to f/11.5. Cloudy? Open up a full stop to f/11. Light rain? Open another half stop to f/8.5, which is a stop and a half wider than the base f/16 we use on sunnier days. And if it’s pouring cats and dogs or the skies are heavy overcast, open up a full 2 stops to f/8 and you’re good to go.
As for the best combination of f/stop and aperture, your final choice should be determined by the nature of the photograph you’re capturing, i.e. a landscape, sporting event, portrait, etc. That said, an exposure setting of f/16 @ 1/100-second can be easily converted to f/22 @ 1/50, f/8 @ 1/400, or f/2 @ 1/6400-second. The depth of field and blur of moving objects within the frame will vary, but the exposure density of each of these exposure variations of the original f/16 formula will remain identical regardless of your final choice of f/stop and shutter speed settings.
Hope this helps.
