Nikon Compressed Raw Format – Lossy or Lossless?
 |
Like most digital SLRs, Nikon’s family of digital SLRs offer the ability to shoot in raw mode. However, Nikon’s raw offerings provide a twist, in the form of compressed raw. The promise of compressed raw files, of course, is that they take up less space and allow you to store more images on your card. Data compression algorithms fall into two categories: lossy techniques, which degrade the quality of your image; and lossless techniques, which reduce file size without affecting image quality. Nikon users often ask whether the compressed raw format is lossless or lossy, so I decided to look into the question |
Using the Photoshop Action Pack with Lightroom and Aperture
 |
If you’re a Mac user who uses Adobe Lightroom, or Apple Aperture and Photoshop, then you might find my Photoshop Action Pack to be a great add-on, as it allows you to add some automated Photoshop functionality to your Lightroom or Aperture workflow. In addition to facilitating more complex post-production workflows, the Action Pack allows you to create a simple procedure that allows you to easily access Photoshop functionality that is not provided in either of those other two programs. From Photoshop filters, to HDR merges, this technique makes it easy to effectively add Photoshop features to either Lightroom or Aperture. |
Gear for the Road
Because different types of shoots require different types of gear – long lenses for an event shoot, wide lenses for landscape, etc. – figuring out how to pack your camera bag for a particular assignment or event can be tricky. But lens and camera selection is just one thing. You’ll also want to consider some other important factors.
Sensor Cleaning Re-visited
 |
If you shoot with a digital SLR, you will eventually have a problem with sensor dust. Even if you never take your lens off the camera, all D-SLRs are susceptible to the problem of dust on the sensor. So what can you do? Fortunately, there are a few new products out there that can help you with your sensor cleaning chores. |
