Delays, delays… but for a reason

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.


Today is dedicate to my late father, Eddy Willems, who would have been 83 today.
