The photo is 40 gigapixels (40,000 megapixels); 280,000 x 140,000 pixels; made of 2947 images joined together; used a Canon 550D and 200mm lens; print size 23m x 11m; stitched file size 280GB [...]
Can someone shed light on what file format would use 7 bytes per pixel (280 GB / 40 Gpixel = 7 bytes/pixel) for something like this? Is it HDR, i.e. more than 24 bits of color?
- robinwauters 16y agoI edited that bit btw, should be 40,000 megapixels.
- lookingsideways 16y agoI imagine the stitched file contains images for various zoom steps rather than just one very large photo.
- 360citiesnet 16y agoHi unwind, This was the output filesize from the stitcher, it was PSB (photoshop large document) format. I think it was so big because it saved the file with an alpha channel which was not entirely necessary in this particular instance. And with some further lossless compression I could probably get the file down to 100GB or so. Jeffrey
