Yes, of course this was what I was doing. I set the camera up so that it's facing directly at the wall then cast parallel to the wall. Doing otherwise can lead to errors, similar to using the dynamic roll cast that Christopher Rownes makes to illustrate certain features of a cast.Dirk le Roux wrote: ↑Fri Aug 09, 2019 9:29 pmGraeme simply stood less square to the cast, facing the wall and casting across his chest. I am fairly convinced the cast was shot perpendicularly to Graeme's position relative to the wall (and the cast). Graeme can confirm. Regarding the velocity values, remember that this was a very laid-back kind of cast.
A dark wall is best, but they can be very hard to find.
While a measure on the ground at the distance of the fly line away from the camera would be nice, I find it easier it be very careful when marking the line and use the marks themselves as the "calibrations stick" in Tracker. Having marks on the ground is just as likely to be erroneous since the fly line may not be exactly over those marks during the casting sequence.
I need to mark up another line. My next one will be a bright yellow DT8. Using lines thinner than 8wt can make digitising the marks difficult (it's hard to see thin lines).
