The DSLR Exposure is a variable which is a function of the three parameters, ISO, Shutter Speed, Aperture Value. Whitespace in low light conditions especially interior under artificial lighting is important. Discuss custom WB settings how to obtain and set. Show example eg outdoors base sunlight shot Shutter Speed, 125, Aperture F8 (depth of field), ISO 100 Take reading from meter Discuss metering modes eg ESP Using Tripod, Delayed 2 sec shot, Remote shooting, taking WB and Shutter Speed compensation Lens
Exposure Stacking Discuss above. Show example. Different exposures at different one stop shutter speeds both over and under exposing. Do Exposure Stacking in PhotoShop. Discuss sharpening in Photoshop using Lab mode, opening jpgs in Bridge, then in camera Raw. Not going to discuss monitors, calibrating your monitor, making sure you have the latest graphics drivers installed.

Tip 2 You need a shallower depth of field to focus on subject/s in the photo. To get a shallower depth of field you reduce your aperture F stops from F16 to F4 to let in more light. If you do this and take photo, youll find the photo pure white, completely blown out. To compensate you need to reduce your shutter speed to let in less light. But how do you know what shutter speed you need to set the camera to? See how many FULL STOPS you had to move to get from f16 to f4. Go on and count em. You simply have to match that number of stops with your shutter speed to achieve the same exposure with a different depth of field! In other words, since you opened your aperture by 4 stops, you simply need to speed up your shutter speed by 5 stops in order to ensure that the same amount of light hits your sensor as it did at f16... THUS ACHIEVING THE SAME EXPOSURE WITH A DIFFERENT DEPTH OF FIELD.
Shutter Speed and Focal Length If shutter Speed is less than 1/100 of focal length then I risk camera shake or blurring interference on photos.
