But in addition to doing that just for the panorama, they also took pictures at different exposure levels by adjusting the shutter speed. To get this panorama, somebody probably went out and used a panoramic head on a tripod and rotated it around 360 degrees taking a number of pictures. An HDRI image is actually composite of a number of different images. What you will see is I am not ten stops lower in brightness, and I still have image detail, and that's because of the way that HRDI images are taken. So taking a look at this HDRI image if I go into my Filter and adjust its exposure, I can bring the Exposure up just like I did with the other, but I can also bring my Exposure down significantly.
Now if I go to a 16-bit or 32-bit image which is the standard for an HDR image, we end up with millions of levels of brightness. Now the underexposed areas I can increase the exposure on and do all right, but I am limited, and that's because this image is an 8-bit image, and that means that there are only 256 levels of possible brightness. The sun is just overexposed, and there is no salvaging in it. So if I bring my Exposure down what we will eventually see is that I am just darkening my entire image uniformly. If I go into my Filter tab, what I can do is enable my Filter and adjust the exposure of this image, and as any one who has tried to play with Levels in Photoshop knows, I am going to be able to shift of this around, but at some point I am going to lose detail. The first is an 8-bit, image and don't let this name fool you, it's not an HDRI. In my Picture Viewer, I have opened two images.
