Sony A900, 70-400mm pan
I thought I’d post a panorama from the Sony A900 and spectacular Sony 70-400mm lens. I photographed this scene for a local business that wanted something catchy on their website. It shows the Santa Catalina mountains north of Tucson, AZ, with Pusch Ridge on the right. The peaks on the left are covered with snow as they’re higher in elevation than the ridge on the right side. Distance from camera to subject is between 5-7 miles (8-11km).
The original panorama is 33,659 x 6767, which would print out close to 9′ wide (9m) at 300 dpi! The resolution of the image would support this, however, on a personal note; I wouldn’t print this particular image quite that large, it’s ok, but not great. I used 16 vertical RAW images, (although 12 would’ve been enough), sent to Photoshop photomerge using the auto mode. The stitch is pretty darn good, I can’t find any obvious weird artifacts. One thing I will say is sometimes Photoshop CS5 will crash when you try to stitch images, and there doesn’t seem to be a fix. It does’t have anything to do with the file size.
The panorama posted here is the full image, but has been downsized to a third of the original, (to 11,500 x 1998), and heavily compressed. I had to do that to make the file size manageable, because the level 12 jpeg came out to 58mb. Also, the website media uploader wouldn’t allow a file size of more than 26 megapixels. The sky is a little blotchy because of the compression, and I don’t have the image quite level, but straightening it would result in too much of a loss of the sides.
You’re probably wondering why the hell I made an image 33,000 pixels wide, only to be shown at 900 pixels wide on a website right? Well, I’m not really sure, but it’s always fun to experiment a little, even if it takes an hour to stitch and save in PS.
