What is High Dynamic Range (HDR) photography? Question from Mark..
Tony answered...High Dynamic Range (HDR) Photography requires that you understand traditional  photography and put your camera in the "MANUAL MODE". This enables you to make incremental adjustments to your shutter speed, from under exposure to over exposure.This procedure will enable you to accomplish High Dynamic Range (HDR) photography.See the images below comparing Traditional Digital Images to (HDR) Real World Images.

We would like to thank Tony for his reply to your various photography forum questions. 

1. What is the function of a camera?
A. To collect or capture light in order to make an image.

2. How does the camera capture light? 
A. Through calibration involving the camera lens, aperture value, shutter speed and sensor.. 
B. Aperture value is analogous to the pupil of your eye it opens & closes based on the “F” stop setting which are light sensitive.
C. Shutter speed is a measurement of time that is analogous to the blinking of your eye.
 
3. What is white balance and how do I set a white balance.
 A. White balance is the measure of the temperature of light which varies according to the time of day with the exception of indoor lights.
 
b. How do I set a white balance? Most cameras have automatic pre sets based on various ambient temperatures. Ex. Sunny day, Cloudy Day or incandescent etc.
 
4. How do I set a Custom White Balance?
A. Set your camera mode switch to “M” Manual.
B. Use a Kodak 18% Grey Card.(purchase at a photo store) This is a control device to set your white balance calibration
C. White Balance can be set at any time of day depending on your preference.

5. What is a Histogram?
A. Histogram is a measurement displayed as a graph that defines dynamic range (from shadows to bright light), and all tones in between.

6. What is depth of Field.?
A. When the foreground and background are in sharp focus in relation to the subject.

7. What is the difference between sRGB and ADOBE 1998  RGB?
A. sRGB is a compressed version of RGB.(resulting in a CLIPPED VERSION(less dynamic range) of  the image.   
B. Most digital SLR cameras can be set(in the menu) to take pictures in sRGB or in the preferred RGB setting.

8. What is the difference between a 6 mega pixel camera and a 12 mega a pixel camera?
A. The higher the pixel value the greater the resolution (for instance the amount of detail is greater in an image with higher resolution).Higher resolution cameras are not necessarily better; the choice depends on whether you often crop or greatly enlarge your photographs and the type of photographs you take most often.
 
9. Why do I lack confidence taking pictures when I first turn my camera on?

A. Because you have not attended our photography course. We guarantee that you will gain the confidence and knowledge that you lack after you take our course.  As a result you will consistently take better photographs and enjoy greater success with your photography.
