Welcome

I am Rod Wynne-Powell, and this is my way to pass on snippets either of a technical nature, or related to what I am currently doing or hope to be doing in the near future.

A third-person description follows:
Professional photographer, Lightroom and Photoshop Workflow trainer, Consultant, digital image retoucher, author, and tech-editor for Martin Evening's many 'Photoshop for Photographers' books.

For over twenty years, Rod has had a client list of large and small companies, which reads like the ‘who’s who’ of the imaging, advertising and software industries. He has a background in Commercial/Industrial Photography, was Sales Manager for a leading London-based colour laboratory and has trained many digital photographers on a one-to-one basis, in the UK and Europe.
Still a pre-release tester for Adobe in the US, for Photoshop, he is also very much involved in the taking of a wide range of photographs, as can be seen in the galleries.

Brogborough Lake — Slightly Less High Wind

I missed out on the Gale Force winds at the Lake, but on the Sunday, it was less fierce so naturally attracted a range of different levels of windsurfer skills. It was interesting to not that André had come along with a commercial hydrofoil, and was finding it far easier to remain aloft, and with less effort than when using his own self-designed and manufactured model. I managed to discuss this with him, and since has more experience, he will revert to his own one to check out its handling relative to his new found knowledge, to assess how much his earlier difficulties related specifically to his design, or to his inexperience. I look forward to learning his thoughts on that.
When I arrived for this visit I did not immediately set up the camera, as I was keen to see whether there were to be some jumpers amongst those attending, and learned from Sam there was at least one possible contender. That slim possibility encouraged me to set up the Benbo tripod and attach the EOS R complete with the 2x Converter, which was one of the primary motives for my getting further experience of using this combination in a sporting situation. The issue is tracking a fast moving subject whilst retaining autofocus, and panning accurately when I know there is a lag involved in my viewfinder relative to the accurate tracking of the subject, especially when trying to keep that subject close to full-screen. What I have been doing is breaking the sequence into short, but linked exposures whilst panning, so any delay does not affect the overall capture too adversely.
There are two separate issues in relation to panning a moving subject, one is maintaining the subject in frame due to this lag, the second is tracking the autofocus point due to the lag; it is this overall aspect I am trying to understand due to the difference between mirrorless and DSLRs — the panning with the latter is comparatively easy to master, since every frame your eye sees is live and accurate, despite the interruption. With a mirrorless camera, every frame compounds the discrepancy so your eye is misled as this delay increases with the length of the action being covered. The obvious, but expensive option is a co-processor channel for the viewfinder, separated from that which is being recorded; in that way the delay remains constant rather than being compounded over the length of the sequence.
Since I am not in a position of having limitless funds available, such an option is likely to be out of my range, so I need to find a happy medium technique that lessens this effect. Another possibility does spring to my mind, and that is have a setting that feeds say, every third frame to the viewfinder to avoid the user having to keep removing pressure on the shutter release; this would have the effect of limiting the delay extending over an extended period. A point I think I need to discuss with Canon. This option would seem possible within the firmware and a means of selecting this option made available within the menu.
Having thought this through since making the jump to Canon’s full frame body, I have put this to Canon UK, but other than acknowledge that I am not the first to make this suggestion, no further feedback or discussion is possible, so perhaps other readers of this blog might also put this suggestion through to Canon, such that it is given due attention going forward. An implementation within the camera’s operating system, if viable, would certainly help the transition from dSLR to mirrorless which would seem in Canon’s best interest in the future.
End of thoughts on that side of the technology, enjoy the fruits of my labours of capturing those who were enjoying the wind and adding to their sailing skills on the water’s surface, or above it in the case of those venturing into hydrofoiling.
