Last week I was working on some images taken back in 2016 in northern Norway at the Ofotjord.
Here we have a panorama image from that pile of up to now undeveloped images. It consists of 13 single horizontal images taken with a full-frame camera. Each image has 6016×4016 pixel. So, each of them has 24 mega-pixel. All images are shot hand-held at 70mm, ISO 400, f8, 1/1600s. It’s end of February and 13:49 😳. See, how low the sun already is at 17:01h.
Another way for creating such panorama images is by taking a wide-angle lens. But this approach has a downside: you’re losing details. For getting only the interesting part of the landscape you have to cut away huge parts of the sky and probably some parts of the foreground. In the remaining part of the image, the details are very tiny. On the opposite, when taking a telephoto lens, you get smaller parts of the landscape but each of the images has more details compared to an image taken with a wide-angle lens. In the end, all these images are stuck together to get a nice panorama image like the one above.
The resulting image of this process is quite big: 23997×2391 pixel and uses about 500MB in 16bit TIFF format on my disk. Converted to JPG the size shrinks down to about 40 MB but loses some color gradings because JPG only has 8 bit per color channel. I explained the problem with 16 vs. 8-bit color-depth already in the past. Next, I resized the file for web-quality. The image above is the downsized version: 9093×900 and 1.7MB.
