Photo Lesson Overview on CGIPix.com
CGIPix is an observation that Nikon, Canon and the rest no longer make cameras,
they make computers that you can attach a lens to.
Here is a basic overview of what it takes to create good, better or best pictures, you decide how much effort you want to put into your pictures.
The basics of photography, all on one page:
Color and White Balance
This isn't dealing with color in the subjuect, this deals with the color of the light source.
All lighting has a color cast to it.
The glow of the light at sunset is a warm red tone.
The light in a shadow is a cooler blue.
By reading the color of the lighting, you can create a different ambience to your pictures.
People always look better in a picture taken at sunset, the warm glow gives their skin a better appearance.
There is a "magic" time in photography, a few minutes after sunrise, and a few minutes before sunset.
If you can take pictures of people, those few minutes before the sun sets create great images.
The few minutes after sunrise are good too, but most people don't look their best in the early morning.
The worst time to take pictures of people is at noon, the color and direction of the lighting are both bad.
Kelvin - The Temperature and Color of Light
The temperature of light is measured in Degrees Kelvin. Here are some commonly used color temperatures:
5500K - Daytime at noon, flash and studio lighting
3000K - Sunrise and sunset
6500K - Overcast day
7500K - In shade during daylight
Here are the lesser used color temperatures:
1800K - Candlilight
2800K - Incandescent lighting, household bulbs
3400K - Tungsten lighting
4000K - Flourescent bulbs - Flourescent bulbs do vary in light temperature
Flourescent lighting falls in the "green" range of the color spectrum, if you manually set WB to daylight, and take a picture in flourescent lighting, there will be a green cast to everything.
With film, white balance wasn't nearly as critical.
If you were shooting tungsten, you bought tungsten film, if you were shooting daylight, it was standard film, and for indoor flourescents, you put filters on after using a color meter to read the light.
Digital cameras have a built in color meter, to perform automatic white balance for you.
Setting White Balance on a Digital Camera
Just like any built in metering, it is not always completely accurate, however, it's usually best to set it on WB-Auto, and correct later if needed.
If you try to set WB manually, it can be so far off the picture is unuseable.
By using the WB-Auto setting, the setting will change as the subject moves from sun to shade, so it is convenient for moving subjects.
To set white balance manually, it is best to purchase a Color Temperature Meter.
Minolta made some really good ones, before they got out of the camera business.
Their meter designs were taken over by Kenko.
A color temperature meter will read the light, and tell you the precise temperature, i.e. 5300K, then you set this value into the camera by using either preset values, or entering the value directly.
Most digital cameras will have presets for daylight, flash, tungsten and flourescent lighting, along with manual entry of a numeric value.
Using a color temperature meter is great for static subjects with static lighting, but in the field it will cost you shots.
One time I was holding a light meter in one hand, a color meter in the other, and watching as the birds flew by.
From that time on, in the field, it's always been set on WB-Auto.
Here are the guidelines for using any pictures from this site:
If the image is stated as being a COPYRIGHTED IMAGE, then it cannot be used. A link MUST be placed from the page that the picture is used, either to Home Page, Thumbnail Page or to the photo's Gallery Page.
The link can be a text link at the bottom of the page, or the picture can be a link.
There is a limit of 10 (Ten) photos that may be used from this website on another single website. After 10 (Ten) photos, permission must be obtained to use additional photos.
Keep the name of the picture as it was originally named, without changing it.
The images on this site are all sized at 400 x 600, that is the size limit for using them on any other website.
The Desktop Backgrounds are for personal use only, and are not meant to be put on a website, unless they are resized at 400 x 600.
You can use the images for commercial, personal, professional or any type of website.
If it's a commercial website, remember that you don't have a model release, so if it's a picture with someone in it, and they are prominently featured, you can't use it without a model release.
When it's a picture of scenery or anything where the people are not identifiable, then you can use it freely.
The "MODELS" pictures are all PREMIUM images. They cannot be used without permission.
It's not a requirement, but send me an e-mail if you use a photo.
