Let the camera do the work

Last Saturday saw another rain related postponement for Prescot Cables, with our chairman reporting the surface water was the worst in 15 years with other games having similar problems. By lunchtime the choice was down to football at Burscough or rugby union at Waterloo. I chose the rugby, as it was easier to get to, the game was less likely to be abandoned, and Birkenhead Park, who have used my pictures, were the visitors. There had been no games for a couple of weeks, so the grass looked rested.

I have posted before about saving files in jpeg and raw. The difference is camera dependent, particularly in the internal processing to create a jpeg. Despite having new kit, I will not revisit the question for non sports photography, the advantages of raw outweigh the disadvantages. However for sports work, it is more finely balanced. The extra processing for raw files on the computer takes time - about 45 seconds per photo, an hour and a half for 120. The D5300 introduces a new issue: even with a high speed SDHC card (80MB/s), the size of the file, about 25MB, is enough to cause an issue with buffering with exposures in quick succession, enough to get a run, but not the goal at the end of it.

"Test the application" is a watchword of these pages, so I decided to shoot entirely in jpeg, to compare results from previous games. I started with the sports mode, on the auto ISO setting. The colours lacked saturation, which had as much to do with the teams' colours as anything else, and was easily sorted with a tweak in Photoshop.
The home side made a strong start.
The auto ISO setting, with its maximum of 3200 lasted me for most of the first half, after which I worked up the scale, to 6400...
... to 12800.
Noise levels were better than the equivalent on the D5000 (where such existed), on a par with what I could obtain on the computer. For the last few minutes, as floodlights were unavailable, I went to 25600, where the full range of noise reduction is not available. There was a lot of grain, which I would have been able to reduce on a raw image.
Switching sports has moments when you forget what is going on - at one point I was thinking, "He's just run the full width of the pitch to join in that pushing and shoving", before remembering it was a maul, and joining it was the idea.

The visitors played more strongly in the second half, clawing back some points, but not enough to prevent a home win.

The game finished just before the next wave of rain arrived, an advantage on this occasion of the kick off time: Paul from our Train Crew went to Burscough and reported a good game in atrocious conditions.

The rest of the pictures from the game can be seen here.

Final score: Firwood Waterloo 36 Birkenhead Park 21.
