When you go through camera menu options, you might come across a number of different options that are related to the way your RAW images are saved. One of those options is typically the type of compression that is applied to RAW files. There are several reasons why camera manufacturers provide RAW file compression options, but the most basic one is to save space. Let’s take a look at file compression options and explore differences between compressed, uncompressed and lossless…
Most of us think we have a good understanding of the camera settings that affect your RAW photos — it seems like common sense. However, the more that you look into it, the more complicated that this topic gets. In fact, no matter how much you know about your camera, chances are good that you have a few misconceptions about the camera settings that affect your RAW photos. Does high-ISO noise reduction change the way your camera records a RAW file? What…
One of the biggest issues many of us photographers face is the gigantic size of our photo libraries, which creates a lot of issues for backing up and restoring images. While we have written a number of articles on properly backing up images, with a recent article on a backup workflow, we have not spent much time on managing the backup size and reducing it. After-all, if the backup size itself is significantly reduced, the time it takes to back…
With Adobe Lightroom being the most popular post-processing tool on the market, one might wonder how good the software really is in processing RAW images. After-all, that’s what we use Lightroom primarily for – to post-process our images and get the best out of them. Having been using Lightroom since the early release versions (dating back to Lightroom 1), I have seen the software grow from a simple RAW editor to a pretty complex piece of software for both image…
While I am getting ready to leave for the upcoming PL fall workshops this week, it was exciting to hear today that Sony is finally going to address the Lossy 11+7 bit RAW issue we have seen on all Sony A7-series cameras (you can read about the Lossy RAW issue in my Sony A7R review). Although the press release below states that Sony will feature uncompressed 14-bit RAW beginning with the A7R II and the newly announced A7S II, I…
For a number of years I have been recommending our readers to convert RAW files from their cameras to Adobe’s DNG format. In my DNG vs RAW article from 2010, I pointed out the reasons why using DNG over RAW made sense – it simplified file management, resulted in smaller files (when compressed or when embedded JPEG image size was reduced) and seemed like a good way to future-proof RAW files. But as time passed, higher resolution cameras were introduced…
12-bit image files can store up to 68 billion different shades of color. 14-bit image files store up to 4 trillion shades. That’s an enormous difference, so shouldn’t we always choose 14-bit when shooting RAW? Here’s a landscape I snapped, then found out later I had shot it in 12-bit RAW. Better toss this one out, right?
When testing cameras, it is not unusual to see a situation when one camera can produce results a bit darker or brighter than another. In some cases, lenses are to blame for this variance, since most lenses cannot ideally transmit all of the incoming light. What this means, is that a lens with a maximum aperture of f/2.8 could potentially transmit less light, which could be equivalent to say f/3.5 in terms of brightness. The latter number is what is…
What do you think is the possibility, when you are choosing and sorting images based on the JPEG previews, that you are going to discard the better-quality image, and keep the lesser-quality one? Let’s take a look at a typical “training” shot for a holiday – noon of a sunny day, blue Ionian sea, bright white limestone pebbles, bushes with dark-green, high-detail leaves (which lose all detail if the shot is underexposed), deep shadows under the bushes. These types of…
No matter what software one uses for post-processing photographs, the process of selecting what images to keep and work on, also known as “culling”, can be quite painful when dealing with thousands of images. And this gets even more painful when working with RAW images, because operating systems usually have no built-in capabilities to view and properly render RAW files. Many photographers end up keeping all RAW images on their computers, because they do not want to go through the…
As good as X-Trans sensors are in terms of performance, most software makers have had some trouble with demosaicing the slightly unusual RAW files in the past. Adobe Photoshop Lightroom has been noticeably trailing behind in this regard even back when version 5 was introduced, as I found out in the review. That’s not brilliant given that X-Trans has been around for, what, almost three years now? To be completely fair, the paint-like rendering isn’t as much of an issue…
With the release of the D4s and D810 cameras, Nikon has introduced a new format to store images – sRAW, or “RAW Size Small”, as referred to by Nikon. Although Canon has had this format available in its DSLRs for years, this is Nikon’s first time introducing it. As a result, a lot of Nikon users are wondering what this format is, how it works and how it compares to standard RAW files. Personally, I had very limited knowledge of…
Aside from various online portfolio solutions, there aren’t many online services that photographers can use for their work. Well, this may change soon. With technology of in-browser RAW processing, Pics.io aims to become an all-in-one photo management and editing solution in the cloud or, as they call it, “Google Docs of photo editing”. We spent some time checking out what Pics.io is all about and we are excited about where this project might take us in the future. Although it…
If you shoot with the Nikon D800 or the D800E DSLR cameras, you might want to check what firmware you are currently running in order to make sure that you are running the most recent version of the firmware v1.10. A couple of weeks ago Nikon released the firmware update that deals with the most annoying bug that has existed since both cameras were announced, where the camera will occasionally freeze, keeping the memory card access light lit for a…
I guess today is a “blow your mind” Friday, because we have a guest post here by Iliah Borg, the person behind the RawDigger software that is used to analyze RAW images. I had a chance to engage in a conversation with Iliah when discussing the noise performance of the Nikon Df, where he not only proved me wrong on my assumption that the Df had exactly the same sensor as the D4 (turns out that they are similar, but…
If you convert RAW files to DNG as a part of your workflow in Lightroom, you probably get frustrated with the fact that Windows does not display DNG image thumbnails or let you view files in Windows Photo Viewer. Windows by default does now know how to read DNG files and the only operating system today that has some support from Adobe, is Windows Vista. Adobe officially released a 32-bit DNG codec for Windows Vista, but it does not work…
The RAW vs JPEG topic seems like a never ending debate in photography. Some photographers say shoot RAW, while others say shoot JPEG. What is RAW format in digital photography? What are the advantages and disadvantages of RAW versus JPEG and why? Should you shoot in RAW or JPEG? Will shooting in RAW complicate your post-production and workflow? These are some of the most common questions that people ask after they buy their first DSLR camera and go through the…
Should you use DNG or RAW format? This is one of the most important questions that you as a photographer need to ask yourself, because it will definitely affect your digital photography workflow. Every photographer has their own say on whether to use DNG or RAW, but it is important to know the key differences between the two, along with their advantages and disadvantages. In this article, I will provide as much information as I can about both formats, in…
If you are running a 64 bit version of Windows Vista or Windows 7, you cannot use Nikon’s NEF codec, because it is only compatible with 32 bit operating systems. It is unfortunate that Nikon has not yet released a 64 bit version yet and it seems like it will stay that way – Nikon basically said that they do not have any plans to develop a 64 bit version of the NEF codec.
