By far the most popular post on this blog has been “How to batch separate & crop multiple scanned photos” (click to link to original post). Thank you for your support, everyone!
While the script seems to have worked pretty well for most of you for the past three (!) years, there was actually a bit of a bug in it, making it not work for non-white backgrounds. This is now fixed!
In addition to fixing the bug, I’ve added a few new features including
- Ability to set output JPEG quality
- Setting a base name manually
- Manually selecting the background colour (in case the auto-selection doesn’t work as it should)
- The ability to automatically save output to the source directory
I hope you enjoy this new and improved script, which can be downloaded by clicking on the following link: DivideScannedImages_improved_v2.zip.
Instructions for installing and using this script are identical as for the original one (click here to see the original instructions, under the “Gimp”heading).
Here is a screenshot of the new and improved DivideScannedImages script’s user interface:
As a photographer I see my camera as a tool with which to capture and create. As an engineer, I see my camera as a wonderful machine and opto-electric toy. But sometimes a situation arises that makes a camera into a scientific tool. To make visible some hidden property of reality itself.
After this poetic introduction, it might seem a little mundane to tell you that this post is about the steam the comes out of my coffee machine. And in fact you don’t even need a camera – this is something that you can see with your naked eye. We own a Delonghi Icona home espresso machine, which looks like this:
Like most machines of this type it has a milk frother side-arm (on the right), that can be used for making cappuccinos. It works by forcing hot steam out at high velocity. The steam’s velocity is controlled by a valve which one opens by turning the round black knob on top.
This year (2013-2014) is a good time for seeing the Aurora Borealis (and its lesser-known Southern twin, the Aurora Australis) – commonly known as the Northern- and Southern Lights. I have my heart set on seeing the Lights with my own eyes in the coming year, so in this post I’d like to talk about how one can best prepare for capturing this natural wonder.
A friend, Bart Vastenhouw, travelled to the region of Varanger in Norway to see and photograph the lights. Here is one of the photographs he came back with:
Bart captured this beautiful scene using a Canon 40D and Canon 10-22mm F3.5-4.5 wide-angle lens. The 40D was a good camera, but these days there are better ones to choose from. The lens is decent too, but for best results you’d want a wide angle with larger aperture (F2.8 or faster).Read More»
Yesterday, Nikon released new firmware for almost all of its current DSLR line-up, namely for the D4, D800, D600, D3, D3s, D3x, D7000 and D3200. Most of these updates only add full compatibility to the exotic new 800mm f/5.6E FL ED VR lens – a lens very few people will ever see or use.
The highlight, for me, is the fact that Nikon has now finally addressed the uncompressed HDMI bug that frustrated D600 videographers. This issue used to be a reason for DSLR videographers to get the more expensive D800, and seemed like a lame up-selling scam on Nikon’s part. No more, it seems!Read More»
In this post I’ll show you two ways in which you can automatically split a (collection of) scanned pages, each containing several photos, into individual image files. My experience is that for this GIMP works better than Photoshop, and as an added bonus: it’s free!
Caveat: The “deskew” operation in the GIMP script only works on Windows computers due to its dependence on “deskew.exe”. If you use Apple or Linux this step will be silently skipped, and the rest of the script will work.
[2013-05-16 Update: the GIMP script can now handle TIF files as well]
[2014-10-02 Handles reading .tiff and .jpeg extensions too. Output dpi set to 600.]
[2016-02-14 The GIMP script has been revamped, with new functions as well as a bugfix for non-white backgrounds. Works for all OS’es!]
Just like you, I also have old photo albums at home. Albums with family photographs, glued to paperboard pages. And you also probably want to have them in digital format – e.g. to share with family members, to protect them from degradation and loss, or just for your digital library.
Work these last few weeks was crazy, and I have yet to tell you about my experiences with the Nikon D600, of which I am now a very satisfied owner.
But since I got this camera, two weeks ago, a major thorn in my side was the official lack of support for it in Adobe Lightroom, my main photo editing / workflow software. It was possible to get around this by tricking Lightroom into thinking the images came from a D800, but this was a schlep and no ideal way to deal with it.
Since yesterday, Lightroom 4.2 is available, and adds supports for 22 new cameras, including the following important mainstream models such as:
- Canon EOS 650D / Rebel T4i
- Canon EOS M
- Nikon 1 J2
- Nikon D600*
- Panasonic DMC-LX7
- Pentax K-30
- Sony Alpha NEX-5R
- Sony Alpha NEX-6
- Sony Alpha SLT-A99V
* Nikon claims that D600 support is preliminary, meaning that there might be small inaccuracies in e.g. white balance that need to be corrected manually.
If you’re still undecided and know that you could use it, yes: I can definitely recommend buying Lightroom. The amount of time it has saved me is worth much more than its cost. Currently retailing at $130 it is cheaper than almost any DSLR lens, and it will add more to the quality of your photo’s than a lens of that price. There are freeware alternatives out there, and I’ve used many of them. In the end I prefer using a single and reliable piece of software over many loose and vendor-specific tools.

Not only is Usain Bolt the fastest man alive, but he is also a budding photographer! :)
Immediately after making history by defending his 200m Olympic crown, Usain walked over to the photographer booth and took Swedish photographer Jimmy Wixtröm’s camera.
Bolt then proceeded to take several photos from his unique point of view. Pretty good photos, too! Now the question may be asked who has copyright of these photos.
If you ever had a digital camera stolen (I have) you know how disruptive and frustrating it is. And in the worst case you may lose valuable photographs, making the loss all the more upsetting!
Did you know that most modern digital cameras store the camera’s serial number in every photo? This digital fingerprint is called the EXIF data, and accompanies every RAW or JPG file that comes out of your camera. While easy to modify or remove, most people don’t ever tamper with this data. Not even camera thieves.
Today I came across a website that can examine a photo taken with your camera before it was stolen, and then search the internet for photo’s taken with it. So if the camera thief or an unsuspecting new owner uploaded any photos with your camera you might be able to track it down!
Visit stolencamerafinder (http://www.stolencamerafinder.com/) to see for yourself. Unfortunately I wasn’t able to find any photos taken with either my or my girlfriend’s stolen cameras online, but maybe your results will be better. Give it a try!
Bottom line: the D800E misses a proper anti-aliasing filter. This probably does more harm than good, so buy the D800 instead, unless you absolutely need maximum per-pixel resolution and know how to avoid Moiré artefacts.
Disclaimer: The D800/D800E are great cameras that differ in subtle ways. Making a purchasing decision based on these differences will necessarily involve “splitting hairs”, but that is probably why you are reading this blog entry, so let’s do that.
I started writing this post before D800E reviews were available online. Now that it’s been tested by dpreview and DxO I have to admit that the D800E is less prone to Moiré than I expected it to be. Yet I stand by what I wrote in this post and I still advise you to get the D800 instead of the D800E unless you know exactly what you’re doing. Read on.
The D800 and the D800E
When Nikon announced their brand new D800 and D800E full frame (FX) DSLRs a few months ago, it was a breakthrough. These cameras push the limits in resolution beyond anything previously seen on 35mm and set new benchmarks in DSLR video capabilities. This is great news, because whether or not competitors come up with even better models, you (the consumer) still win. So, we know that they are excellent. All he reviews tell us so. The big question in photographers’ minds is probably whether to get the D800 or the D800E. The “E” sounds somehow more Exotic and Exclusive, and promises even sharper photos. Given this, the D800E’s 10% higher ($3300 vs $3000) price sounds justified. Sort of like a D800 “de luxe” edition, right? Not necessarily.Read More»
