RAW vs JPEG

http://live.pirillo.com/ – What format is better for digital camera: RAW or JPEG? Most digital cameras in the "prosumer" to consumer range don’t really save out to a RAW file format, and instead always save in JPEG.

JPEG is a lossy compression format, which means that some data is lost when the image is compressed.

RAW is essentially just that: the raw data is saved to the file without any compression at all, and thus no data loss.

Professionals like using RAW files because they don’t want their camera doing any processing at all, so they can manage the files on their computers as they see fit.

Which one is better? For consumers, JPEG is the way to go: it’s ubiquitous and support for it isn’t going to go away anytime soon. If you’re a professional you’ll probably choose RAW.

What do you think: RAW or JPEG?

http://live.pirillo.com/ – What’s better: PNG and JPG? The truth is that these formats actually serve two difference purposes. JPG caters to the photographic market, whereas PNG is generally considered to be a replacement for the patent-encumbered GIF format.

According to Webopedia, JPEG is:

Short for Joint Photographic Experts Group, the original name of the committee that wrote the standard. JPG is one of the image file formats supported on the Web. JPG is a lossy compression technique that is designed to compress color and grayscale continuous-tone images. The information that is discarded in the compression is information that the human eye cannot detect. JPG images support 16 million colors and are best suited for photographs and complex graphics.

And PNG:

Short for Portable Network Graphics, the third graphics standard supported by the Web. PNG was developed as a patent-free answer to the GIF format but is also an improvement on the GIF technique. An image in a lossless PNG file can be more compressed than a GIF file of the same image. PNG builds on the idea of transparency in GIF images and allows the control of the degree of transparency, known as opacity. Saving, restoring and re-saving a PNG image will not degrade its quality. PNG does not support animation like GIF does.

Geotag Your Photos with Freeware

Geotag Your Photos with Freeware

I don’t think there’s an easier way to geotag your digital photos in Windows. Check out the free Panorado Flyer:

JPEG image files can contain supplementary information (so-called Metadata). Technical metadata as described by the EXIF standard can contain fields for GPS data, like geographical latitude/longitude, altitude, and track. The Panorado Flyer tool enables you to get the coordinates of the place where the picture was shot and insert them into these fields. You can do it manually, using a dialog window. Or, if you have installed the Google Earth client (can be downloaded for free), you can search for the location there, drag it to the center of the map window, then change to Panorado flyer, grab the coordinates and insert them into the image selected, without typing any numbers.

Don’t think I’m going to do this terribly often, but certainly will consider it for future use.
