Thank you all for your kind comments.
All three have a somewhat interesting story behind them. Briefly, for image 1 (quarry) I had to wait about 45 minutes for the sun to peak through because it was a
very overcast day. When I first saw the scene, it was awash with sunlight, but by the time I hiked back in there and got the camera setup (5x4) the sun was gone. I wanted the sun! So I waited...after nearly 45 minutes I saw a small hole in the clouds and wondered if I'd be fortunate enough that the sun would make its way through. I was and the image was burned onto the film. While I waited, I remembered something my photo mentor said, he quipped, "If you're setup and ready for something to happen, you might not get the shot, but if the camera is in the bag, you
definitely won't get the shot!
For image 2 (brook), I was using my 10x8 and was standing literally in the middle of the rushing water which was rushing by about 7 cm under my tripod head. The current was of such force that I had trouble standing there! Not the best of spots to setup a 10x8 camera.
For image 3, it was really straightforward other than the fact that I had to stand in the middle of a road to get the viewpoint that I wanted. Again, using the 10x8 for this shot was, perhaps, not the best choice considering camera position!

My wife watched for cars whilst I made the image. I just love the ghostly remains of the portico or whatever that was attached to the front of this house at some point in the past.
