Hey, menace, nice truck. I see it in the 05+ Tacoma thread alot.
These two pics look OK, actually. What are your bad ones like? Blurry? Out of focus? Dark? Bad color?
Your D40 is a smart little machine. You have all sorts of options to play with.
You will want to use a tri-pod or similar instrument and the camera's self-timer. Using both will pretty much eliminate blur. It looks like you're doing this already.
It looks like in these photos that your flash fired. Maybe you used the "Night Portrait" mode on the dial. That setting is good enough in most cases, but it can create some bright spots in the image like you see here on your grill and your side marker reflector.
Basically, what I've found that works is to set the Mode Dial to "P". This is the Program Mode and you have the option to adjust some settings to help your night pictures out.
Once you are in "P" mode:
- Make sure your camera is shooting at the highest resolution (6.0 MP I think for you) and at the highest image quality. Your settings are probably like "High Quality" or "Fine". Just don't use "Normal" or "Economy".
- For the most part, you should turn the flash off so that your camera calculates shutter speed and aperature based on the available light coming through the lens, rather than what it's going to see when the flash goes off.
- Change your ISO setting to 400 or higher. This makes your photoprocessor in the camera more sensitive to light. You might get some grainy-ness at the higher settings; adjust it down until you like what you're capturing.
- Set the White balance to meet your light conditions. It has pre-sets for flourescent, tungsten, daylight, etc. Just set it to what your light conditions are, or experiment for different color effects.
The camera should do the rest.
If you want to dive deeper into the camera's settings, switch the Dial Mode to "S". From there, you will be able to tell the camera how long you want the shutter open for and it'll do the rest. Remember, the darker it is, the longer amount of time you want the shutter open.
Good luck.
