The exposure of a photograph is influenced by three settings:
1. The aperture
2. The shutter speed
3. The ISO

                  Short Exposure                 Long Exposure

ISO- traditionally, ISO represents the light sensitivity of film. Lower ISO means lower sensitivity and finer grain on photos. Higher ISO settings are generally used in darker situations to allow a faster shutter speed. For example an indoor sports event when you want to freeze the action in lower light. However the higher the ISO you choose the noisier shots you will get. ISO 100 is considered “normal.”

So… What do I use in lab?

• – Higher ISO (2500) because I’m typically shooting in low light conditions
• – Medium aperture F5
• – Moderately fast shutter speed 1/320
• – Adjust as necessary…

Camera Modes:
P: Programmed Auto – Camera automatically adjusts shutter speed and aperture for “optimal” exposure
S: Shutter Speed Priority – You choose the shutter speed while to camera automatically selects the “optimum” aperture
A: Aperture Priority – You control the aperture, camera selects the “optimal” shutter speed
M: Manual – User controls shutter speed, aperture, and can manually set the ISO

Where can I find the shutter speed and aperture readout?

ISO is a little trickier… For the He Lab camera, press the ISO button then adjust using the shutter speed wheel
NOTE: You can’t adjust the ISO if it’s in automatic mode; look in manual to see how to turn off auto-ISO

Still can’t get your exposure to look right? Use an auto mode that gives you a nice exposure, look at what the shutter speed, iso, and aperture are set to. Then, go to manual mode and put in those settings to get the photo you want

Having issues with color? Consider manually setting the White Balance (see manual)
