So HDR is all about making pleasant pictures, if handled appropriately. Let us delve into more detail as to how we could get the best out of HDR.
A quick searchfor HDR give a whole lot of material available online. I am not going to write one more tutorial, but thought it would be good to give the links to the stuff I found helpful.
Before jumping on the tutorials, some key points
- No special camera feature if required for this. If you have a Auto Exposure Bracketing (AEB) Mode, it would be really helpful.
- If you do not have a AEB Mode , look out for the Manual Mode. In manual mode you should be able to control the Exposure setting. If you neither have AEB nor manual mode, sorry u might be out of luck.
- When using the manual mode (with AEB too), a tripod might be handy, depending on the length of exposure.
HDR (at least based on today’s digital cameras) involves two major steps
- Use the Digital Camera to shoot the same scene with different exposure (minimum of 2 shots, better 3 – Exposure value of -2,0 & 2)
- Use an appropriate software to post process these shots into a single HDR image and apply Tone Mapping.
The Post Processing
A wide Varity of tools are available in the market for converting the multiple LDR (Low Dynamic range) Images to a HDR like Adobe Photo shop CS2, Photomatix from Hartford, Artizen HDR and I think even GIMPhas an option for processing HDR.
Out of all the once that I had tried, my favorites are Photomatix and Adobe Photo shop CS. Both of them have the ‘Align LDR Images before generating HDR’. It is really a amazing feature that could suffice for the absence of a tripod.
Here is a exhaustive write up on HDR with both Photomatix and Photoshop.
