Science Buddies: "Ask an Expert"

I need help on getting more sources and information on digital photography and cameras. I was wondering what websites that have good information.

Exactly what aspect of digital photography would you like information on?

Try using a search engine like Google and typing in the term "digital photography." I checked it and it brings up "Digital Photography Review" a website that I go to a lot for information on cameras. Also check out Michael Reichmann's website "Luminous Lanscapes", Rob Galbraith's website also has a lot of information. I've intentionally left out the URLs to these websites so I'm not simply doing the research work for you.

Hi liannah!

Typing "digital photography" into answers.com gives an excellent introduction to digital photography technology.

Hi liannah!

Another thought:

Typing your project question: "Which digital camera, olympus or canon, has brighter color?" into answers.com yields a large set of websites. Some of these may be useful to your research.

Hi there,
I would try to modify the experiment away from a "product comparison" test.
If you must stay this course, in the end try to identify "why" one product is "better". When I have seen these types of experiments, the results tend to be too influenced by the "marketing" rather than the technology.

Try to understand how they produce "brighter colors".

What exactly does "Brighter Colors" mean? Brighter when viewed as a printed picture or perhaps measuring.

Many ccd's used in digital cameras will pick up infra-red images too, test if your camera's can see into this spectrum.

You can do a very interesting experiment if you dig a bit deeper into ccd or "Charge Coupled Device" image analysis.

Here is a link with a bunch of image analysis freeware.

Good luck,

I agree with Mr. Lewandowski that you should look into CCDs and maybe even CMOS sensors.

Keep in mind that there are few CCD manufacturers and it is common to have different digital cameras (brand-wise) using the same sensor.

Also, your experiment on "brigher colors" is a bit difficult due to couple reasons:

1) Lens and optics : Are the shutter and aperture specs of the cameras you are testing the same?
2) Settings: Keep in mind things such as ISO (sensitivity), metering, etc.

In short, try to find cameras with comparable tech specs to conduct your experiment so you have a level of control. However, I believe that it is quite hard to do what you are tryign to achieve.

Like what Mr. Lewandowski said, you should look into analysis of CCDs and how it grabs light in order to produce an image.

Not sure if this has come up but a topic that might be worth looking into: depth of field.
