Hello Everyone,

I posted a question this past week about upgrading to a 20D and got a mixed response. One of the responses being upgrading for the sole purpose of night shooting/low light conditions. I have had several unpleasant experiences with the Rebel XT in low light conditions, some being very disappointing even with the 430 EX flash. Last night, I was trying to take a shot of the city off of a bluff... it didn't go well at all. In fact, it didn't even want to take the picture after setting the ISO to 100-200 and adjusting the apperature. Does anyone have any suggestions on how to make this work?

Also, aside from ebay, are there any good photography classifieds that I could buy/sell in?

Thank you for your response! Nothing is more disappointing than having a 'good shot' gone bad!

Do you tryed out to take a night shot? Long exposure? If that, then flash is inutile and not used. I used my XT to take pictures at very low light conditions and in night shots too with espetacular results. Can you send-me some sample, or complete camera settings and detais of subject?

The reason that it did not want to take a picture is probally because it could not focus corectly.

I think emenresu might have it, I find it hard to shoot at night, I try and focus of something bright as far away as possible and flick it over to manual and then just leave it. I was also REALLY amazed with the noise reduction with the XT, I never used it before, but for the last nightshot challenge I did a 25min exposure with it and I was blown away. i dont think changing bodies will help, just a bit more trial and error is required thats all! When I started doing star trails I started a book with all the settings, and conditions etc to compare to the results. My first results were pretty heinous!

stick with it mate!

Focus isn´t an issue. If you know how your camera focus system works. To know it read this: //www.night-ray.com/comments.php?id=82_0_5_0_C

The real issue with night shot focus is the lack of distance information on Kit Lens or other cheap Canon lens. Using L lens or 3rd party lens with distance info, you can set the focus to infinite or to distance you want. If there is high contrast place in the scen, try to ptu focus there selecting only the AF point you want to use.

I guess I need some instructions from you! I am pretty new to this... I tried using the auto-night focus (on the creative dial). It did not work at all.... in fact, it kept shooting bursts, but would not take a picture. Also, I tried the "P" mode, I set the ISO to 100 and 200. My shutter speed was much slower, but I still didn't get a good shot.

I will read over these articles, but a how to from any of you would be awesome!

I was on a cliff trying to shoot over the mountain/city area. There were plenty of lights... I just wasn't getting it. I was using the standard 18-55 lens.

The 18-55mm lens is just fine for night shots.
What I have found to work well regarding the focus on the 350D/XT is to zoom all the way in, manually focus on something, then zoom back out. The auto focus does not work well on most cameras unless there is something that has a defining edge with a difference in contrast. You will find it hunting back & forth trying to find something to lock on to.
Personally, I shoot in manual mode and experiment with the shutter speed and aperature. try and use f/8.0 or f/11.0 for a sharper image and more depth of field (which will help).
If you are going a second or longer, set your noise reduction on, as it will help in a longer exposure.

Those bursts are the autofocus assist light. Basically, your camera/flash is trying to illuminate the area in order to find a focusing point. Unless you are trying to illuminate the foreground, a flash is not needed for taking a shot like Brad posted. I would just turn it off.

Be SURE you have a tripod for night shots. You often have to use such a slow shutter speed that it makes keeping the camera still essential.



This shot of mine was taken on a tripod, ISO 200, f/11, & 30sec exposure. If I remember right, I was using manual focus as well. It was shot in Aperture Priority mode.

Hope that helps some.
