In this post, I’ll present a solution to a common problem that occurs quite often nowadays: Merging photos from multiple people into one continuous, consistent stream. It is definitely not the first solution to that problem, but since I couldn’t find a tool that solves this in exactly the way I want, I just did it myself, as usual ;)

There are some advances in technology that are actually steps backwards: features that look nice on paper, but always get in the way when implemented in reality. One of my pet peeves in this category is the Exif Orientation Tag, a little flag present in JPEG files generated by digital cameras that causes all kinds of havoc. It’s one of the places where the old proverb »the road to hell is paved with good intentions« holds true, because the idea behind this flag is a good one, whereas the flag itself is a product of pure evil. But let’s start the story at the beginning …

After six years, it was time for my good old Fujifilm FinePix S9500 bridge camera to be replaced by a more recent model. It served me well during all the years and still works perfectly. However, it’s only equipped with a 1/1.7-inch sensor, which limited its usefulness to the range of ISO 80 to 400. Even my second camera, the compact FinePix F200EXR, fares a bit better in this respect, but that’s just because it’s a little bit newer (2009), not because it has a larger sensor.
During the DSLR boom of the recent years, I occasionally felt tempted to upgrade to a APS-C or at least Four-Thirds model, but I was always kept back because of the miserable handling: Not having an electronic viewfinder means that adjusting any parameter except exposure compensation and ISO requires to move the camera away from my head, look at the rear screen and put it back. Somehow most people don’t seem to mind that this is extremely awkward, but I do.
In 2010, however, Sony fixed that problem with its SLT technology that premiered in the A55. I was close to buying that camera, but then I read about its heat issues, so I wanted to wait for the next generation of SLT cameras instead. This has been introduced in fall 2011, but there has been no direct replacement for the A55. So I decided to go »all in« and buy the top-of-the-line model – the SLT-A77V, especially after its very positive reviews. Here’s what I think is particularly good and bad about that camera.

Converting images of scanned documents into proper PDF files is quite a hard task. What I usually want is
This sounds simple and reasonable, but I’ve yet to find a tool that does exactly that. Adobe Acrobat handles the latter two constraints well, but I don’t know how to set the paper size when importing an image. This is no problem when using a normal vector graphics or page layout tool, but then you usually don’t have much influence on what nasty things the PDF output code does to your images. Furthermore, you mostly end up with useless cruft in the PDF files, like XML metadata or even fonts (even though there’s not a single letter of text anywhere in the document). So I decided to end this mess once and for all and write my own image-to-PDF converter. Here it is: pdfgen.
