If you have completed the first exercise, you should now be aware that increasing the ISO makes the sensor more sensitive to light, thereby meaning that you can increase your shutter speed. In unchanging light conditions, a one stop increase in ISO (from 100 to 200, or from 200 to 400 and so on) allows a one stop increase in shutter speed (from 1/30 to 1/60 or from 1/60 to 1/125 etc.)

The next section is about a 'creatively correct' exposure - how different combinations of ISO, aperture and shutter speed can give identical exposures but different effects.

Read pages 22-33. Complete the exercise on p.30-31. You can post images from either a stationary object or a moving object, or both if you so desire

I would recommend taking these pictures outdoors, since you're going to be shooting with very narrow apertures so you'll need a lot of light (or a tripod!).

Remember to work in manual mode and post technical information (ISO, ss and ap) with your sooc images.

Many cameras allow 1/3 and 1/2 stop changes to aperture, so here's a list of aperture values in one stop increments:


You don't need to take an image at each of these values - just select 3 or 4, representing a decent range

ISO 200 f2.8 ss 1/1000

ISO 200 f4 ss 1/400

ISO200 f5.6 ss 1/80

ISO200 f8 ss 1/80

ISO400 f11 ss 1/100

ISO800 f16 ss 1/100

ISO800 f22 ss 1/50
