[Fixed] Chromecast Not Working

• Hold down the reset button for around 20 sek.
• Update the Chrome Home App on an Android Mobile
• Follow the setup instructions on the screen

Strangely enough the Android fix changed the Chromecast settings on the Chrome browser in Linux. So if it does not work on your PC, try to update the thing on your phone. 

DSLR: Force Sharper Images on Night Pictures

Night photo: F8, ISO 100, shutter decided by Sony SLR-A58

If you want a photo that is sharp all over you could select an aperture priority, and just shoot. But then the camera will try to get an image with a fast shutter speed. In order to do so the ISO-number will rise. As a consequence the image quality will suffer.

Here is a simple recipe:

• Set aperture to F8
• Set ISO to around 100 to 400 or so
• Let the camera calculate the shutter speed

As a result of these settings you will get a fine depth of field because the aperture is F8. The camera cannot choose a lousy quality of the image, because the ISO is defined as 100 or a bit more. Since the ISO and aperture are fixed the camera is forced to calculate a longer shutterspeed - and as a consequence your picture will be sharper with more details.
