1. low light - look for a camera that has ISO settings higher than 400. There are a few (very few) that go to 1600. If a camera has a f2.0 lens (Canon G6) it is more desirable that a camera with a f2.8 lens.
2. AA batteries vs proprietary batteries.
Generally it makes little difference if you are using NiMH rechareable AA batteries.
3. Most small cameras have an automatic cover that protects the lens when the camera is off.
Most small cameras need an adapter to install a filter, this makes the camera bulky.
4. The smaller the f-stop number, the brighter the lens. See answer 2 above.
5. Type of memory card: the main difference is the physical size of the card. The other difference is cost to you. If the camera maker is building a small camera, he wants a physically small memory card.
Sony memory stick came about from greed. Sony brought out the memory stick so that they can control it. That means if you want to build memory sticks, you must pay Sony to do so.
The same thing applies to the xD memory card. It is jointly controlled by Olympus and Fujifilm.
The SD card and Compact Flash card is controlled by a consortium. Therefore lower prices for you.
6. RAW and TIFF -
TIFF is a photo file that has no compression.
RAW also has no compression and is a copy of what the camera sensor sees. It does not contain any white-balance, and other fine adjustments the camera will apply to the photo. You must use software to make the subtle changes to the photo. RAW is used by advanced photographers, it is not for everyone.
Many people are interested in the hotshoe until they find out the price of flash units.....$300 to $400.
8. video formats....there are software programs to change one format to another, so it is not important.
I would not dare try to explain the histogram, so here is a link to someone who can:
Here is a link that is very handy in explaining many aspects of the digital camera. You should bookmark this site, as it is very helpful:
i've searched this forum to see if there was a checklist for a little better than average camera. there are so many features, i'd like to know which ones really make the camera perform well. i hope this makes sense.
things that i am interested in are what features i should look for
- low light
- are AA battery cameras as good in terms of # of pictures you can take to proprietary batteries
- what accessories should i buy when i first get the camera besides a memory card. for example, when i bought my camcorder, people said that i should buy a uv filter to keep the lens from getting scratch.
- i know nothing about f stop, but i see it in reviews, but i don't know how to tell if one models f stop is better than another model
- is one type of memory card (sd versus compact flash for example) better than another
- how important is raw and tiff support? i know they are file formats, but much past that, i'm lost
- hot shoe. i have this on my camcorder and am interested to know how much this is used on a camera. i've been paying attention to people in the street that are using cameras, but so far i haven't see anyone using this feature. yes, i know that isn't a good survey, so i'd like input from the experts here
- are there any problems with the movie format being something other than avi. this seems to be popular.
- how important is it to have histogram? i'm not sure what it is, just that the canon models that i've read reviews of, say canon doesn't have this feature.
any help would be greatly appreciated helping me put together this checklist.
