This Is A Grass Snake Isn't It?

Another (probably) really straight forward ID confirmation which illustrates how much I've still got to learn. Trail-cam caught unusual "visitor" today (I've taken to leaving it running until early afternoon as quite a lot of activity during the day).

Am I right in "Grass Snake"?



I've reduced size and quality so hopefully not to massive a download.

I find the colours from the trail-cam very bad - but easily adjusted in any video editor so it's not a problem. Above video has been trimmed but not colour adjusted. I'm sure most grass snakes I've seen before have been much darker.

Also, my reptile book best ID is grass snake but patterning/colour is closest to the SE Europe & N Italy variant.

n.b. The trail-cam has been "adjusted" to focus closer so, from my focus calibrations,  the snake is passing probably 80 cm away from the camera.

(Sorry for such un-challenging ID requests).

Thanks
Ian
