The other day, when I was scanning old negatives with a new Canoscan 9000F MK II and SilverFast 8 for my piece on SilverFast’s Multi-Exposure, I kept thinking about the reasons any photographer should want to keep using film and a scanner to digitise his or her images instead of using a digital camera. That made me contemplate some of the disadvantages and benefits of scanning film and those of image sensors…… Read More Using film and a scanner or shoot digital?
During the years I had my dark room (the real thing), I remember I had to burn areas to get a better exposure across the photo. It was the analogue version of trying to achieve a high dynamic range — high enough at least to represent most brightness values across a photo based on what the film emulsion was capable of. Today, with a scanner, the dynamic range of any scanned photo is not just limited to capabilities of the film emulsion but also by the dynamic range of the scanner itself. It’s as with digital cameras: there are only as many f-stops available as the sensor will “see”. Just as with digital cameras, you can achieve a higher dynamic range by combining an exposure for highlights and one for shadowy areas. This method works only with scanners that allow this “manipulation” and the right software to work it. SilverFast is by far the best application with which you can apply this technique, having been awarded the European Digital Press Association’s “Best Colour Management software of the Year” prize in 2008 for it.
You are often required to transcode from one format to another. When shooting in consumer AVCHD or professional XDCAM you will need to transcode to a format your NLE understands and can work with smoothly. But just as often you’ll need to transcode from your NLE’s format to another for optimised delivery. There are a couple of applications that are specifically developed for this task, and each has its own merits.… Read More Transcoding video for delivery, an overview and best practices
GoPro finally released the Protune firmware, a couple of days before they announced their new HD Hero3 cams with 4K capabilities. Although the news of the HD Hero3 sort of siphoned all the attention away from the Protune release, the latter is worth at least as much focus.… Read More GoPro Protune firmware: a brief test
x264 is a video codec developed by a group of open source developers. Contrary to what most people believe, the x264 codec is only free for noncommercial use. Both Episode and Squeeze use a commercial form of this codec.… Read More The x264 format in Episode and Squeeze
A year ago, the Atomos Ninja and the Cinedeck Extreme field recorders were about the two only ones that could record video directly to a high-quality codec using a video camera’s HDMI output. Today, Black Magic has at least three devices that are capable of recording to Uncompressed the same way.… Read More Uncompressed video via HDMI becomes popular again
We have taken our camcorder, mounted it on a tripod and panned a scene that shows a medieval cathedral in the Gothic style. We first recorded the scene using the camera’s built-in AVCHD codec, and then repeated the panning movement, recording with the Atomos Ninja.… Read More Comparing an AVCHD with Ninja recording
