HDR photos: What’s the difference?
HDR or High Dynamic Range photos look great! But, is this any significant? Yes!
For those who don’t know much about HDR photos: they are photos that have a bigger range, so they can capture from dark, shadow areas till bright, sunny areas.
With nowadays cameras, we already have a nice range, but HDR provide a much bigger range. Photos will appear much real and more natural, enabling us to see more details and more “visible” areas.
Here are some example I took in my weekend at Gerês – beautiful region on the top of Portugal – and Guimarães:
Today, there aren’t much HDR cameras, so the alternative is to just take several pictures with different exposure times and use them to compose a HDR picture.
You can use Photoshop, FDRTools or – my favorite – photomatix. Some cameras like Canon already have a AEB automation so you just define the intervals of the exposers (eg. -2, 0 and 2 of exposer).You can see a lot of HDR pictures over the web, like the:
Portugal Vivo em HDR group on flickr.
But it is rare to see nice photos that show you the “normal” photo and the HDR version.So, here is a collection of photos in their normal state (as capture by the camera) and their post-processed HDR result. I think this is the easiest way to understand the benefits of HDR and why it is so important.
| Normal Version | HDR Version |
|---|---|
| This is the normal version, that the camera usually takes. | This version is built with the image on the left and two more similar images, one with less exposer and the other with more. |
