This is a terrific collection of online photography tools. The collection is organized in the following sections.
Maybe not everything is for you, but I am sure you will find something enjoyable or useful.
Perhaps you have been enjoying your DSLR very much and are curious if the shutter on your beloved DSLR has approached its life expectancy. Here are some information on how to find out the total shutter actuations.
For both Windows and Mac OS X users, the best tool to use is the ExifTool by Phol Harvey. Simply run the following command in a Windows command window or in Mac’s Terminal window (Replace MyPhoto with the photo file you want to get the shutter count):
exiftool -ShutterCount MyPhoto
ExifTool is a very powerful command-line utility. In Windows, simply drag and drop the photo over its default name “exiftool(-k).exe” and a console window will show you all the Exif information.
You can rename it to “exiftool(-k -a -u -g1 -w txt).exe” to get it to write the Exif information into a text file. This assumes that the shutter actuation count is actually recorded in the Exif.
For more details on how to use ExifTool, please check out the software’s website.
Canon DSLR users may want to check out the utility program called EOSInfo (a Windows only program). Please note the following on the EOSInfo website.
The shutter count information is available *only* on Canon DIGIC III/IV DSLRs *except* the 1D* series. This means that EOSInfo will display the shutter counter for the 40D, the 50D, the 450D, 500D, and the 1000D. It will also show the shutter counter for the 5DMkII, but the camera must be power-cycled before the value is updated. The shutter counter will not be displayed (or will be displayed as “0”) on the 1D*, 5D, 10D, 20D, 30D, 300D, 350D, and 400D. It’s not that I have anything against the owners of those cameras, but simply that the Canon SDK does not support retrieving the shutter count for them. UPDATE (08/06/2009): Apparently, Canon has removed the facility for checking the shutter count on the 500D …
If you cannot seem to find the total shutter actuations of your camera, it is possible that the information is not there. The camera manufacturer may choose not to implement it, or it may be hidden somewhere in the camera but not written to the image file.
I am curious if most people know who has the largest market share in CMOS image sensor. Is it Canon? Nope, it is Micron Technology Inc (see this media presentation from Micron). So I guess it is not so strange that Micron makes the 2MP image sensor for the iPhone.
Lots of posts on internet forums are speculating what the new Nikon professional DSLR will look like. From trickles of hints and suggestions by someone with claimed “insider” information, the new camera will feature a “revolutionary feature”. It is unlikely just a full frame sensor because Canon had it since November 2002 (the Canon 1Ds 11MP). Some European websites (eg. here) have some more details that look very very interesting. However someone pointed out that the specs are just copied from Tom Hogan’s prediction. For a good history of Nikon D3 rumors, please check out this page by a fellow photography blogger.
For the timing, most speculate late June or early July announcement and around August for initial shipment.
Nowadays almost everyone has a camera phone. However the image qualities of the photos taken from these camera phones are mostly crappy, unless you have one of the high-end camera phones (eg. Nokia N95). For people who just don’t want to carry a decent camera, here are some tips for taking good pictures with a camera phone.
