Pixelicious – working with Jpeg Files

There are so many file formats out there. Jpeg files are among the most common for photography. Jpeg is a standardized file format created by  the Joint Photographic Expert Group (which is where it’s name comes from).  Jpeg was standardized in 1992, so it is a very mature standard, and probably could use a little updating, but part of the problem is that no one wants to deal with the problems that a new standard would cause. I guess we are stuck with it for a while. Everyone loves jpeg for its broad compatibility and ease of use. I have never been a big fan of jpeg files just because of the lossy compression. Lets get at the heart of the pros and cons of jpeg file format. Cons Lossy Compression Blocking artifacts at low bit rate No lossless capability Pros 24 bit color high details & high quality pictures reduced file size it is the most used graphic file format approved as standard in 1994 standard file format. broad range support From the pros/cons list, it may seem that the pros outweigh the cons, and for some uses that is true only because this is not currently a better alternative. The problem is that we are all very impatient. We will not wait for a file to load, so jpeg was created to share images on the web at an acceptable quality level while making the files very small. Every time a *.jpg file is saved it compresses the file to save space. When you save a file you are given a choice on how much compression to apply, the more...

Backyard Birds

I spent a few more hours out in the snow viewing more birds. All images were made with a canon 6d + tokina 300/2.8 + 2x TC. Most images were made around f8, trying to squeeze as much sharpness out as possible....
Fall in the Ozarks

Fall in the Ozarks

  The weather patterns are so unpredictable. It is still fall, and we got 8-10 inches of snow and ice over the past several days. It was quite a treat for me and my family. Growing up in Huntsville, Alabama we did not see snow very often, and anything more than an inch or two was very rare indeed. Photographing in snow has provided me with much greater challenges than i thought it would. Obviously, the cold weather has it’s own unique challenges, and just cold weather is not really a problem for me. Blowing snow gets in everything. similar to sand, but then it melts. I was out shooting with my 300/2.8 and got covered in snow while shooting. when I came in and everything started melting water slipped inside then lens and started condensing on the inside elements. I was sure that I bricked the lens. I ended up taking it all apart, carefully removing the lens elements with a spanner wrench, and was able to dry it all out. Luckily, I was able to put it all back together. Aside from the physical challenges to shooting in the snow, finding good compositions was also a bit difficult.  Finding interest and good storytelling elements in a snow covered scene can be a little more difficult than i expected. I ended up focusing on the local wildlife. We have a ton of songbirds here, and they were all trying to find the little bit of food that was around. I put out a little bird seed and waited.    [nggallery...
