I have recently bought a canon 600d and I can take photos using the LCD screen and everything seems fine but when i tried to use the view finder the camera has trouble focusing and the flashing green light does not turn red when focus has been achieved. I cannot take pictures when using the view finder no matter if i try and take a photo in doors or out.

Can anyone help?



Answer
make sure you check your lens barrel, make sure you already change to AF not MF

How can I increase light in my camera without increasing the ISO?

I have a Canon 600D and I love photography. I have one question though. I want to try and use manual settings to try and learn more, and often when I try and take photos inside, they are a lot darker, but if I increase the ISO, sometimes it doesn't make enough change and if it does lighten up the picture, then there is a lot of noise (dots/slight blurring) in the photo. I don't want to use the flash either as this can sometimes drain out the colour in the subject of the photo - i.e. people become a lot more pale and the colours are not as vivid. Is there a way to make a subject lighter without doing post-processing/editing and also a way to lighten the subject while keeping out "noise"? Thanks so much.


Answer
There are two ways to do what you want - increase the ISO which, as you've already discovered, gives poor results or invest in the Canon EF 50mm f1.4 prime lens. Trying to use the standard 18-55mm f3.5-5.6 zoom in low-light means using a high ISO or using the flash.

The Canon EF 50mm f1.4 is 2-2/3 stops faster than your zoom at 18mm and f3.5 and 4 stops faster than your zoom at 55mm and f5.6.

Hypothetical example of what that means:

Suppose you're using the 18mm end of your zoom wide-open (f3.5) and to achieve a shutter speed of 1/100 sec. requires using ISO 3200. With the 50mm f1.4 lens at f1.4 you could use ISO 500* and achieve the same 1/100 sec. shutter speed. Now suppose you want to use the 55mm end of your zoom wide-open (f5.6). To achieve the same 1/100 sec. shutter speed would require using ISO 8000 since f5.6 is 1-1/3 stops slower than f3.5. With the 50mm f1.4 prime lens at f1.4 your ISO would still be at 500*.
*NOTE: Your camera probably doesn't allow you to change the ISO in 1/3 stop increments so you'd actually use ISO 400.

Learning about the Exposure Triangle which consists of ISO-Aperture-Shutter Speed will greatly benefit you. http://www.digital-photography-school.com/learning-exposure-in-digital-photography

When using the built-in flash on your camera you can soften the light by simply placing a sheet of tissue paper over the flash. Using an external flash like the Canon Speedlite 430EX II will definitely improve your flash photography since you can bounce the flash off the ceiling which gives much better lighting.

So invest in a 50mm f1.4 prime lens or an external flash or both.
