Can I make an HDR image from a single Nikon D40 RAW file?

I’m shooting RAW on a Nikon D40 and wondering:
- Does a single D40 RAW file contain enough dynamic range to create an HDR-style image?
- Are there any camera settings or shooting tips I should use when capturing RAW files if I want the best result for HDR processing later?

You cant create an HDR image from a single Raw file with any canera (since you can't magic dynamic range into existence) but you should be able to get the ultra contrasty tonemapped look from the D40 without difficulty. It's not the detail that matters for this it's the noise, and in favourable conditions (see next paragraph) the D40 is not noticeably worse than other DSLRs.
For the best results you should aim to maximize the dynamic range of your single exposure which means minimizing noise. To do this you want to get plenty of light so you don't have to raise the ISO sensitivity. You should also try to underexpose a little to be sure you capture the highlights.
You could enable active D lighting to do the underexposure for you, but I would recommend paying close attention to the camera settings (esp. ISO) to ensure you minimise noise.

A single RAW file cannot create a true HDR image, because HDR requires more dynamic range than one exposure captures. What you can do from one D40 RAW file is produce an HDR-style, heavily tone-mapped look.
For the best result from a single exposure, try to maximize the dynamic range you capture in-camera:
- Use the lowest practical ISO to keep noise down.
- Give the sensor plenty of light when possible.
- Protect highlights carefully; slight underexposure can help avoid blown highlights.
- Watch exposure closely rather than relying entirely on processing later.
Active D-Lighting may help by biasing exposure to preserve highlights, but careful manual exposure is still important.
So: yes, a D40 RAW file can be useful for HDR-style processing, but no, it won’t give you true HDR from one shot alone.
