Ah, I hear you ask, where are your blog posts?

Coming! I am in the process of finally finishing my long-awaited “Photography Cookbook”. This is taking all my time.. also precipitated by a few new things I acquired:

New 15″ Retina Screen Macbook Pro – the old one had a harddisk failure during  Santa shooting, so I had no option but to buy a new one. First impression: I can never go back to an old screen.. all I see there is pixels. Use a retina screen computer, and never look back. Also, the solid state drive is nice – no disk warm up and slow things down (and make noise).  Quick judgment: recommended wholeheartedly.

iBooks Author – my iBook will be available as a PDF and as an Apple iBook. The latter choice means I am using Apple’s iBook Author. Not a bad app, but with a steep learning curve and with several annoying bugs. I am hoping for a version 3 soon. Quick judgment: recommended with some reservations.

Rest assured I will catch up and answer the outstanding questions (and: keep them coming).

And now.. my quick beginners’ lesson for the day:

If you are still having trouble understanding exposure, try this analogy:

Exposing correctly is like filling a bucket (=the sensor) of a given size (=its ISO) from a faucet (=the aperture), by holding it under the stream of water for a given time (=the shutter speed).

Think this through and try to understand how the three variables, duration, faucet size and bucket size, contribute to filling a bucket to the top, no more and no less. Just like shutter speed, aperture, and ISO.

Too little water and the bucket is too empty (“underexposed”); too much water and it spills over the top (“overexposed”). That should help you understand how these variables interact.
