Thanks for the advice on 1.4. Will upgrade. Would like v2 - maybe a birthday/ Christmas present idea...

Andy

Hi Tel,

I actually have 1.2. I think when the next update came out there were some issues with it so I didn't bother at that time. However probably ought to now - although I am not sure it offered anything noticeably better (Can't remember).

I haven't gone to v2 as it costs

Andy

I echo the above positives about using Lightroom (albeit I have version 1.x). I have the book for v1 that Steve has mentioned - excellent!

Also a great thing one can do with any file is to make any number of virtual copies within LR and so apply any number of different effects/ treatments/ processing styles - and be able to simultaneously view them alongside each other and all without changing the original file, or significantly increasing the amount of memory used to store them.

It seems to be based in Portland, (Ohio or Oregon)

The K10d body only is more expensive than the K20d with kit lens!

I get Outdoor Photography which does ... photography, and whilst reviewing some cameras, it also reviews useful things like outdoor gear etc.

I like AP for some of its technical articles

I have this tripod (the Giotto that is) - and think its pretty good and tend to take it most places. It is very versatile, albeit not as quick to set into awkward positions as a uni-loc/ benbo. However one can still get to ground level with a centre column that is either replaceble with a short post, or can be set to 90deg and other angles.

I have managed to 'nip' my fingers occasionally with the leg-release catches. I had the cheapest Giotto ball-socket head but that broke quite easily. Jacobs let me trade it in and I replace it with the small Manfrotto head (as I have another Manfrotto pan-tilt head that uses the same QR plate)

Go for it Amin!
In the link you put up, there are a couple of suggested books by Harold Egerton. I have another of his books called Stopping Time - a whole load of his piccies. He was a pioneer in this field.

He has some piccies taken early 1950s of atomic bombs going off, 'freezing' the mushroom cloud in the first few microseconds of going off and an exposure time of 1/100,000,000 second (can't do that with your K20D!).

I wouldn't suggest you try that in your shed
The camera set-up was 7 miles away!

Yes, I left the shutter open (so room had to be dark). You can get the trigger to fire the shutter. Using the cable release socket - you need to get the trigger circuit to short the centre pin to the outer. Trouble is, the delay might be too much. I haven't tried it myself

Instead of an IR beam split, you can get the trigger to fire a flash using a small microphone (so sound triggered - good for catching the bursting balloon!). And yes - why not motion sensors as well

Hi Amin,
The following link may help a bit.

Basically you have an infra-red beam transmitted to a sensor LED that is connected to a trigger circuit. When something interrupts the beam (eg water drop or insect), the trigger circuit is activated and will then send a signal to fire, eg, a flash. You can usually have some control and delay the time it triggers the flash, in this way timing the flash at different phases of a water drop splash - to catch the coronet, or the tower or whatever.

The idea of two beams is that you focus the camera where the beams intersect, and can catch an insect/ bird in flight when it breaks both beams!

I can't at present find somewhere that makes a commercially available one. I though Warehouse Express had them, but haven't managed to search for the right thing. They weren't that cheap

Hope this helps

Andy

EDIT - the circuit I made is, I think, a bit simpler than the one in the link. Also Maplin is a place to get the bits in UK

Hi Stefan,
Yes I did make it specifically for this type of thing, but also hoped to use it to capture, eg, insects in flight - however I don't have the time to try it out!
