Flash freezes water

This exposure was taken on Fuji Iso 800 film at an indoor pool with the Nikon F90 + 180/2.8 lens wide open. The exposure was 1/500th f2.8 with a burst of flash from the SB26, the camera and flash have a special mode allowing synchronisation at all speeds.
It is the flash which has frozen the water streaming off the swimmer's arm.
I have published this picture a few times but it is now hidden in archives.

Shutter Speeds

The shutter speed dial from my old Nikon FE. In the Auto position the camera is in aperture priority mode. It is up to the photographer to select apertures the cameras set the shutter speed for what it thinks will be correct exposure.

In manual mode the speeds which can be chosen are from 1/1000th sec to 1/2 second (The White Numbers). The orange numbers are slow speeds from 1 second to 8 seconds. M90 is a mechanical speed (No electronic shutter) and B is bulb for exposures longer than 8 seconds. In most digital SLRs the speeds are displayed on an LCD and inside the viewfinder on the information bar.


This image from inside the camera's viewfinder display shows:

From left: Metering option of matrix, 60 which represents 1/60th second shutter speed, f2.8 the set aperture.

The scale from + to - with zero in the centre shows slight over-exposure.

The number in brackets is the frames remaining.

Calumet adds Flash value


Just £5.86 buys this wonderful PC adapter for any SLR which does not have a sync cord socket for flash. It undercuts the opposition such as Jessops by at least £3.
It is one of a slew of flash related products which my employers have launched this month. Others include a radio flash trigger for £59.99 nearly 1/4 the price of its nearest competitor.
There's also a radio shutter release and cable shutter releases.

Nikon P50

Divide the P5000 by 100 and you have Nikon's latest pocket marvel the P50. It has a 28mm (35mm equivalent) wide angle lens, AA batteries so is truly go-anywhere, optical viewfinder, manual mode, Iso 64-2000, 8.2 Mega Pixels and vibration reduction (VR). So pretty much everything needed on a compact.
I'll have to give up recommending the P5000 and move to this newer model.
Have yet to try it out......................
