Photographic Innoventions: Adding Light to the Sun

Posted on by Scott Thomas
Earlier, I showed how the use of software can add light to a badly underexposed photo. What if I told you there was a way to do the same thing using your camera and not having to do any post-processing in software. Would that be worth something to ya? Looking at the photo below taken … Continue reading "Photographic Innoventions: Adding Light to the Sun"

Photographic Innoventions: Color of Light

Posted on by Scott Thomas
Not all light is pure white and will have a certain color temperature. Engineers express this in degrees Kelvin which you might have used in your high school physics or chemistry classes. Our eyes see color temperature as color casts like blue, green or red. Have you ever taken a picture and have it look … Continue reading "Photographic Innoventions: Color of Light"

Positive Exposure Compensation of +0.3 EV.© Scott Thomas Photography 2007Nikon D70/18-200VR, 1/50s, f5.6, 200 ISO Exposure Compensation allows you to adjust the exposure measured by the camera’s light meter and telling the camera to allow more light in (positive exposure compensation) or less light in (negative exposure compensation). On your digital SLR camera, look for … Continue reading "Photographic Innoventions: Dialing in Digital Exposure"

Spaceship Earth. Copyright © Scott Thomas Photography 2007Nikon D70/18-200VR, 1/10s, f/5.6, 1600 ISO, -1 EC, 135mm Focal Length Many people have sent in questions about how to get good low-light and night photography pictures at Walt Disney World. The key is to get enough light to your digital camera’s sensor to record a well exposed … Continue reading "Photographic Innoventions: Light Sensitivity"

Photographic Innoventions: Shutter Speeds and You

Posted on by Scott Thomas
Shutter speed is the time for which the shutter is held open during the taking of a photograph to allow light to reach the image sensor in a digital camera. A fast shutter speed will freeze the subject but needs plenty of light. A slower shutter speed needs less light and a more stationary subject … Continue reading "Photographic Innoventions: Shutter Speeds and You"

Cinderella topiary at Epcot’s Flower and Garden Festival. Copyright © Scott Thomas Photography 2007Nikon D70/18-200VR, 1/160s, f/11, 200 ISO, -0.3 EC, 18mm Focal Length In digital photography, exposure is the total amount of light allowed to fall on to an image sensor. It’s really quite simple even though there’s a lot of science and engineering … Continue reading "Photographic Innoventions: Mechanics of Exposure"
