I have a large image that I made (a river running to the Washington coast on the Olympic Penninsula) by montaging together 32 pictures I took on my T3i in photoshop. It is 24,362 × 8,801 pixels. It looks like this (a smallified version): The photoshop file was greater than 2 gigabites (which photoshop could manipulate but could not save). I saved it as a .jpg which is ~95 MB. There is a lot of detail in the full size version. For example, there is a child with a ball on the beach on the far side of the log pile and pebbles and reflections of individual grass blades can be seen toward the right side. I could print things like this out on one of those large format printers, but I would like to display it on a moderate sized screen or put it on a website in a way that people could click on the screen to zoom in in 2X jumps. The zooming in is very immersive. It really sucks you into the shot. I want to use this effect for a local conservation group's website. A company does make a device to put your camera on to take pictures like this. They also have a website to do the montaging and get codes to embed images on other websites, to display the results. All this is dependent on getting their hardware (not cheap) which I am not now inclined to do. I can do this with photoshop and Preview (Apple's pdf viewer), but I am wondering if anyone knows of other possible options, particularly for websites.
