Thanks for all the responses. This is what I managed to get. I see I uploaded the original, not corrected. Need to get a flash capable of what is required. Thanks for all the tips.

Thanks for the clip. Amazing technology these days.
How did you insert the clip? I see that I can load a url, but can I insert a jpg? I wanted to show what I did manage to achieve. Got the technique right, was just interested in the mechanics, which this video shows superbly.

Do you know what determines the exposure time, in electrical impulse that turns the sensor on and off, or how long shutter is open? May be stupid question but I just can not get my brain around the shutter being open for 1/8000 of a second.

I was messing about recently with the drops of water concept. To try and freeze several drops in a row, I set the shutter to 1/8000 of a second, and shot on continuous mode. The noise was quite frightening in that I kept on thinking "How long will it take to wear the shutter mechanism out?". Thinking about it afterwards, I was wondering if the shutter actually closes when shooting in continuous mode. Are the sensors merely switched on and off, or does the shutter actually close. I hope to goodness that the mirror stays locked up when shooting continuous! Does anyone know?

I have had my K-5 for a month now, and shame, my poor K20D is feeling very neglected.

Question about the duty cycle of the shutter

My K20D is 500 shy of 30 000 in 14 months, I'd better start saving. My iST did about 60 000 in its life, and was sold in great working order.

I received the camera with some faulty pixels on the sensor (about a dozen) and am thankful that has not got any worse, but I am watching carefully.
