Description from developer:

“These are files that the default QuickLook plugins doesn’t handle. It was built to scratch an itch, as I was finding that quicklook is useful for searching through source before I installed new programs, and the first file I would want to see, the README was the only file I coudn’t.

The first Quick Look Plugin geared specifically for photographers.

From the plug-in’s website:

“With SneakPeek Photo simply click on the unopened photo file (no matter where it is, even on your card reader) and hit the space bar. Up pops the picture into a large view that immediately gives you the detailed information you need. On the top bar, the much needed basics such as the type of file, its size, f-stop, focal length, color Sfile (sRGB, ProPhoto, etc) even a mini histogram. But there’s much more. Also on this view you’ll see buttons which will give you Exif data, all the camera settings, a Loupe View with high resolution zooms, and a large Histogram to see the blueprint of your shot. If the photo is geotagged, you’ll not only see the coordinates, but a nifty map of where the picture was taken. Plus there’s even a link to a more detailed map online.”

Cost: $10

QLFits 2.0
Preview FITS header+images/spectra directly inside the Finder!
Released: 2009-07-16

QLFits allows you to see FITS files right into your Finder, without opening the file! It automatically generates on-the-fly a colorized header, with images and/or spectra below! It even supports multi-extension fits files. Even better, it detects ESO keywords, and build automatic links to the proposal abstract, the file summary, and even the weather conditions!


• Colorized header.
• Quick summary + Full header
• Automatic detection of ESO keywords
• Links to ESO archive seeing/prog id pages (when possible)
• Support for multi-extensiom FITS files!
• On-the-fly preview of 2D images!
• On-the-fly preview of 1D spectra!
• For 2D images: On-the-fly thumbnail of 1st extension that contains data
• For 1D spectra: On-the-fly thumbnail of the spectrum
• Display of the value of the “OBJECT” header keyword, with large fonts.

Notes: images pixels are scaled linearly (it produces in general better results than linear or logarithmic-zscaling). If no data are present in the FITS, only the header is shown.

Thanks, Cédric!
