With the DA*300mm you need to do an adjustment for using both together. With mine it was quite a bit different to using the 300mm on it's own. Also you need to stop down to at least f/5.6 on the lens. It isn't at it's best wide open with the TC.

Will they tell you when the Amazon delivery will arrive? Amazon just say between 7am and 10pm which means staying in waiting and waiting...... A Crystal Ball would be just what I need

Thanks......Interesting to see how this is done. I thought it was with mirrors

There's nothing new under the sun. These paterns were originally produced mechanically on a yoke called a 'Harmonograph'

I thought all screening could now be done via blood tests. I had 3 blood samples taken at the same time about 3 months ago and they said they were all OK apart from the cholesterol one which was the average for the UK.

I normally use an Eye-Fi card at home so I usually include a Grey Card in the 1st shot and then check WB + Exposure + Focus on the PC before proceeding. I've probably taken a cordless flash reading first using IR to trigger the flash.

For exposure burnt out whites are more important than the grey card, but the greys should all be the same RGB value such as 118R 118G 118B Any editor will read the values from a JPG

A lighter shade of grey card is supposed to be better, because of noise. i.e. WhiBal http://michaeltapesdesign.com/whibal.html

A free source of grey cards are paint swatch samples

With flash indoors especially with some bounce. It's worth taking into account that the colour will have been warmed up by furnishings etc. from it's daylight value. I have various values pre-set on my K-5 under the WB button such as (K2) K1 4000K..... K2....4500K.....K3.....6500K

I only ever use manual off camera flash.

I'm not sure if they still do B&W, I used to use AH Leach in Yorkshire for large prints ....

I had an enlarger and stuff to go up to 20"x16"

You could ask Ilford if they have any customers that do it.

Edit: https://www.onevisionimaging.com/ took over the colour printing side of Leach in 2009. They do list Fine Art B&W?

That should be excellent Much better than the overpriced Flektogon and cheap Vivitar
