Very nice Alan.....

Here is my latest offering for the Spring Challenge.  I have an Olympus OM-D but can't say I have mastered the Live Composite mode it offers:

Getting there Chris, live composite will be reviewed during tonight’s Zoom session - see you at 2000 hrs

Thanks for the show tonight Barrie. All understood. I have the same facility on my Canon, its called the "Guess" button :-)

Cheers, what Guess Who

Thanks Barrie for the presentation on still life light painting. I can see what I need to improve now - most of it.  Also, thanks to Alan for setting the meeting up.

[Bazza]

Thanks Chris, if you or anyone else want more help then we could try FaceTime as alternative, just call or email with dates and time as not doing very much....

PS understand no restrictions on timing now with Zoom if two or three attending...

[OPS Notices]

Zoom is still 2 for unlimited. I read 3 but it said 3 or more is restricted.

I'll catch up later.

Notes on Still Life Light Painting for those attending tonight’s Zoom session

1. Olympus have a fairly simple and exclusive mode for this genre of photography “Live Composite” where ongoing images are taken on same original but not affecting highlights unless hand light.
2. Non Olympus users would need to utilise Bulb mode but instead of making further lighting that could effect the overall image/exposure you would need to build image upon image with several masks.
3. To get around this the likes of Harold Ross use layer masks to build upon the initial exposure in bulb mode once each photo has been stacked and realigned
4. This effect gives a vintage masters effect / colour effect which I think is dependent upon type of light source used - eg Kelvin measurement and your white balance
5. Inverse square relationship in lighting does the opposite to what’s expected, eg “The intensity or brightness of light as a function of the distance from the light source follows an inverse square relationship. ... Notice that as the distance increases, the light must spread out over a larger surface and the surface brightness decreases in accordance with a "one over r squared" relationship”
6. As with most lighting, the more oblique angle of light to subject would improve texture and highlight distinguishing features where a direct light does not give any depth to image, the same would apply to shadows
7. Therefore light source need to be close ( eg inches from source) and moving back and forth over relatively small in a short period
8. To provide the initial angle of light I have recently started using a flash then build upon this with hand torch or smaller light always keeping the direction away from camera lens that would cause highlight and reflections.

Thanks for the notes Barrie.  I will try again with an initial flash and closer light source.  I am hoping to get at least one photo in a PDI comp in future.
