I know you probably already know how to do this.īut I think it’s worth going into some details to cover how you to make sure you have captured the whole dynamic range in your bracketed images. There are 2 ways to shoot for different exposure: The final image blended with luminosity mask If you like to learn more about HDR, check out the HDR resource page under Articles in the top menu.

I won’t go into the details of HDR software here because this tutorial is about how to blend picture. Automate the process of merging with an HDR software.There are 2 options on what you can do with the bracketed images. Darker and brighter exposureīy bracketing multiple exposures automatically or manually. Using the example above, I took a darker image to expose for the walls and a brighter image to exposure for the interior (the area behind the door). This is the reason why we merge pictures together – to create a high dynamic range image.Īt the moment, the only way to see details in the brightest or the darkest part of an image that is clipped is to take the same image with a different exposure. The same can happen to the darkest part of the image too. You get blown out highlights or highlights clipping. The dynamic range of the scene has exceeded that of the camera. You can see there are no details in the highlights because there’s simply no color information recorded on the image sensor. I took this in the Vatican City at midday (can you see the Swiss Guard?).
You can, but it will look like this: Highlights clipping That doesn’t mean you can’t take a photo with your camera. The picture above gives you an idea of what I’ve just explained to you.Īs you can see, sometimes you just can’t fit what you see with your eyes into the image sensor of your camera. “Stop” is how the camera measures light quantitatively (for example, 1 stop down from a shutter speed of 1/200 sec is 1/100 sec).īut in real life, light in a given scene can be as high as 20 stops.
The current technology of the digital image sensor can only record light of up to about 14 stops. You see, although the technology is constantly evolving, our camera still can’t capture what we see with our eyes.īecause the human race is better than the machines! (sorry, I’m a fan of The Matrix) The result is also thought to be more natural and realistic. “But We Can Use HDR Software”īut exposure blending allows you to have more control over your image. In other words, it’s to create a high dynamic range image.Īpart from that, blending is also used frequently in composite photography. The main reason is to overcome the limited dynamic range of our digital camera.
