I get home form work and its dark, so as its my first week owning a 350D with 10-22 Lens, can anyone give me some tips on the settings for shots inside my house.

My shots basically always look dark, so i want to know roughly what F stop (I heard it mentioned alot so must be important), exposure, ISO, etc should I use.

All my shots so far look rather the same regardless off setting. I have been trying to have a very slow shutter speed (hand held), but seems no diff.

As I seem to be able to make all the shots brighter in PP, do I really need to worry if the origonal RAW is dark?

Any Tips would be great.

Basically: Higher ISO = Brighter but grainer (more noise)
Wider apature, or F stop (smaller number) = Brighter but less DOF (Depth of Field)
Slower shutter speed = Brighter but movements get blurred.

So basically, take your pic, or combine a couple, depending on what you're going for.

Hope this helps.

you may want to have a look at these great free online courses - some are interactive so you can see the effects of changing - aperture, speed, focal length.

Wow those links look good.

Is a tripod a must if i want to combine shots?

Is a lens apperture od 3.5 to 4.5 (my 10-22mm Wide angle) enough for interior shots?


Thanks All!!

Difficult to say as it depends on a) how light the interior is and what time of day you intend to take the photo - so nighttime then you would need a flash gun or more and b) what shutter speed and that depends on if hand holding or tripod.

so lets say you are using the lens at 15mm on a 350D
Guide for shutter speed to avoid camera shake
1/focal length x crop factor
= 1/ 15 * 1.6 = 24
so you should be able to hand hold at 1/30th is the nearest complete F stop

I would say a tripod is a must to get good alignment and probably to avoid camera shake

Is a tripod a must if i want to combine shots? No, but it would help. Is a lens apperture od 3.5 to 4.5 (my 10-22mm Wide angle) enough for interior shots? Probably not. Here's one way it would help. You could get down to f/11!

Oh can my lens can go to f/11. I sort of assumed it was limited to 3.5 to 4.5.

If I have a really long shutter speed will that help as more light will get the the sensor?

you really need to understand exposure - go and have another look at those links I posted and read the sections on exposure, aperture and shutter speeds
that will answer your questions and others you have not realised you are about to ask

you lens has a range of apertures as follows
@ the 10mm end from F3.5 to F22
@ the 22mm end from F4.5 to F27

This link might help, too.
Virtual Camera (http://www.camerasinteractive.com/index.php#)gives users hands-on experience operating an Single Lens Reflex (SLR) camera.
Four tutorials explain focusing, aperture, shutter speed and exposure.

Learning the basics of how a camera works mechanically, and how that all affects exposure, are an essential first step in the learning curve.

is one of the best books with illustrations to help you get your fingers around the concepts.

Well I have ordered Mastering Digital Photography, but intill it arrives I have all these questions. Those links are starting to help though.

Thanks for your help!

as you read through the links I posted includes virtual camera posted by photosguy - just come back with things you dont understand.

Im guessing that your lens opens 3.5 to 4.5, so unless you're doing aperture priority and placing your camera on a tripod, you're getting underexposed images.

Try this

Put camera on a tripod, or a desktop
Set your cam to Av use 5.6
Let the shutter take care of itself.
See what you get.
