John, that color is the usual tint of any SOOC images I shoot. Since the request was for an SOOC, I didn't WB in ACR.

Larger sensors generally provide better image quality, dynamic range, etc. However, if you haven't exceeded the capabilities of your current camera, then why spend money on more equipment.
--Bob

I can handle a camera hanging loosely on a strap, but add the bouncy nature of a rubber strap and I'd never want to get near one.

Now, that's having fun with photography.

A couple of things. First, considering the seemingly senseless rules, I'd skip the trip. It seems more trouble than it's worth. Secondly, I've photographed in a cave a couple of times. Flash works, but I'd make a multi-layer filter for the flash. This would be of gray transparent plastic with the darker layers towards the outside and the center clear. This would be the equivalent of a VND, but with the center clear and the edges the darkest. However, you can't use flash, for whatever dumb reason, thus this useful and proven idea is worthless.

Most importantly, don't overdo it with the lights. You'd be surprised at how little light one needs once one's eyes acclimate to the environment. Most importantly, have fun. Bring two sources of light, perhaps three. I'd never go into a cave with less than three flashlights.

Jack, Bob, Val, Marty, Greg, turp77, and John, thanks for taking the time to check this out and comment. I always appreciate that.
--Bob

Thanks to all of you for stopping by and the kind comments and thumbs. They are appreciated.

Treepusher, I agree with you. Rainbows just really never look good in black and white. I've done sunrises and sunsets in black and white and those have worked, but rainbows just don't make it in monochrome. Thanks for looking,
Bob

Thank you very much, Jan. It's always nice to have you drop by and comment.
--Bob

Nice, John. There is enough detail and mystery to hold the viewer's attention. The goat part was funny, but not so funny...if you know what I mean.
--Bob

Very nice, Jim. Good composition and the colors are quite nice. Well done.
--Bob

Bob, thanks for stopping by and commenting. It's most appreciated.
--Bob

Thank you very much for the compliment, kpmac.

NIce.

Thank you, TBerwick.

Nicely done, especially the composition. The house is not centrally located. Including the surrounding, especially the sky, really emphasizes the loneliness of the subject. If one wishes to give personification to a house.
