To Convert or Not to Convert? We Examine this Question (Introduction)

My Adobe PDF reader updated the other day, and I suddenly received this notice when opening a file:

The first thought I had was: This is might not be “OK”. Next came the questions: Should I worry?  Was I about to lose some important information? and Do I really have to do anything about this?

Naturally, these pop-ups and the questions they raise aren’t limited to PDF and Adobe. We see messages like this show up often in many of our software apps – notices of missing plug-ins, fonts that can’t be located, files that can’t be opened because the software is outdated, etc.

In this series we will take a look at various data formats, what information is contained in the formats and carried through in format conversion, and how software works to open files and give us access to the data. While Bevara generally advocates preserving and not converting, we realize that preserving data in its original format is not the answer for every situation, so along the way we will discuss when to “normalize”,  the times when it might be fine to yield on conversion parameters – maybe we can accept one font in place of another or perhaps our customers will never need a particular feature associated with the file — and how to tune formats to get the most of out of them when normalizing.

We are fortunate to be able to spend time with many people, especially within the archivist community, who have already invested a great deal of  thought into how and when to preserve their data – we’d love to hear from you. Send us your thoughts, questions, or suggestions to and we’ll be happy to address them in future columns or answer you directly.

We’re integrating Cairo into Revenge

What that means is additional ways to display your document data. We’ll now support even easier access to thumbnail views into your document repository and allow both image (RGBA) and SVG displays of CorelDraw and other formats.

Even obscure formats deserve support

You have them. We support them. We’ve been adding formats like palette-less PCX to the portfolio. Keep the support requests coming!

New Year, New Formats!

We’ve been working hard to update our supported formats and are looking for beta testers for Corel Draw.

Always Accessible.  Always Open-source.

We’re committed to open-source Accessors. We’re currently migrating our Accessor repository to a public repository on GitHub ( . You can clone it from:   

If you don’t see your Accessor there yet, drop us a line at, and we’ll move it to the top of list. As usual, we appreciate any source code contributions, so if you modify the code, please let us know and we’ll be happy to add it to the repository.

Ever wonder what’s in your files? (Part 3)

In our last installment, we saw a Leica DNG image (courtesy of that had a main image and a thumbnail. As with many DNGs, this image also has metadata, some of which is:

Camera: Leica M8
DNG Version:
ISO speed: 160
Shutter: 11.3 sec
Focal length: 50.0 mm
Embedded ICC profile: no
Number of raw images: 1
Thumb size: 320 x 240
Full size: 3920 x 2638
Image size: 3920 x 2638
Output size: 3920 x 2638
Raw colors: 3
Filter pattern: RG/B
Daylight multipliers: 2.097456 0.946061 1.128163
Camera multipliers: 2.104980 1.000000 1.255310 0.000000

However, much of this metadata is contained in a MakerNote EXIF as opposed to other metadata storage options such as general tags and  XMP. This range of options raises a challenge in figuring out how to save and retrieve the embedded metadata when preserving DNGs.

Ever wonder what’s in your files? (Part 2)

In this installment we’ll continue exploration of popular image formats. Here’s a Leica DNG image courtesy of We see that it has a main image (with no post-processing  color correction) and a small thumbnail. Stay tuned for what else is in there!

Ever wonder what’s in your files?

Here’s a Canon CR2 image courtesy of There is a main image, a full-size thumbnail, as well as and a small thumbnail, and some metadata. You’ll see that the main image is not balanced. We offer automated processing options such as color-correcting, white-balancing, filtering, or leave this processing to you.

New Year. New formats!

We love this time of year, since we always announce new formats. We’ve been working hard on getting some new RAW formats out. Look for our demo of Hasselblad and some new Canon formats!
