HDR Exposure Calculator – useful web utility

HDR Exposure Calculator – useful web utility from HDRsoft

calculator_resultsToday I would like to mention a small but useful web utility app from HDRsoft (creators of Photomatix Pro and the company I work for).

Have you ever wondered how many exposures you should take to capture whole dynamic range of the scene and to create beautiful HDR image? 3, 5 or maybe 7? This app will help you with that – it calculates how many exposures you need exactly! No more guessing!

To use it, simply visit the link below:

HDR Exposure Calculator

It’s very easy to use, you basically just need to enter exposure of highlights and shadows (which you can easily measure by pointing your camera at brightest and darkest spots of your scene using¬†Spot Metering) and then you can click on the large blue Get Exposures button to get the results – number of exposures you will need to take as well as their shutter speeds (and exposure bias value).

Featured photo – Just After the Rain

Time for today’s shot. Although that’s not very common in summer, during my stay in Chania, Greece it was raining for a few hours (it was storm in fact). It stopped pouring in the late afternoon and as soon as it did I grabbed my camera as I knew what it meant – some amazing light. And I wasn’t disappointed. There were some stunning clouds ranging from blue to yellow and there was amazing reflection which made the scene look even better.

Dynamic range in this case was pretty crazy so I went with HDR processing – I took 5 exposures (in fact it would be better to capture 7 but I was shooting hand held so it was not an option) which I then merged to HDR in Photomatix Pro.
