The PSD and TIFF formats are very similar; both retain all of the size, quality and separate layers of the original image. You can reduce the size in these formats by flattening the image, but you’ll lose the capability of reworking the individual layers later. The TIFF format also offers a lossless compression called LZW while still maintaining layers. That said, I always flatten my images before I send them to anyone else because I want to be sure that they can’t be altered once they’re out of my hands.

The fact is, storage is cheap. A quality 2-terabyte external drive can be had for $100 these days. Because I never want to compromise the future use of an image that’s worth saving, I always store my files in uncompressed TIFF or PSD format with layers intact, and in at least two locations, using a subject-cataloging system that facilitates easy retrieval. I also keep the original RAW files in a separate folder just in case new technology or unforeseen demand renders them useful again.

Kolor Autopano Giga 2.5 For Difficult Panoramas
A new version of Autopano Giga offers a number of features useful to those who want to tackle extremely complex and/or massive panoramas that less capable stitching software is unable to handle. Examples include wide-angle captures with distortion, panos with large undetailed areas such as skies or tiled multiple-image composites such as HDR and Gigapans. Some of the additional features of Autopano Giga 2.5 are the ability to put together pano sequences captured from a moving airplane with multiple points of view and compositing panoramas taken with a fisheye lens. The new program has automatic color and exposure correction and a feature called Neutralhazer anti-haze filter to brighten skies. Go to www.kolor.com to see the possibilities. The folks at Kolor are based in Europe so the prices are listed in euros. This isn’t the cheapest panorama-stitching software, but it’s the most powerful. Kolor also has available a less robust version at half the price for those with a smaller budget.
