When I took photography (B&W same as you), we were told by the instructor that he dumped all the used chemicals down the drain, as the college was on a public sewer system and the developing and printing chems were non-toxic.
He did say that if you used a septic system, that was another story and because his home was on septic, he brought his home chemicals to the college to get rid of.
Color chemicals are much different and (20 years ago), were toxic and not allowed to be dumped in the public sewer system. We didn't do color, but the question was asked and answered.
You could call B&H and ask them, as they deal with the same chemicals we used.
Don't know if this would do all you are asking about but look at this article - https://www.cnet.com/how-to/control-a-dslr-camera-with-your-android-phone-or-tablet/
The program they talk about gives you the ability to do anything (allegedly ;-) your camera can do. Many camera's today will allow you to enter names for a photo (or, as you said, suite #, etc.) so if the camera can do it, they say the app will allow you to do the same with your phone.
Or maybe they were using the phone like a monitor...
Hi Suzanne, as the others have said, a bit more space around the dog in the first couple would be better but they all seem a bit under exposed. What camera and settings were you using? With a dark subject and bright background, cameras tend to under expose. To compensate for this you'd need to over expose by 1-2 stops.
In the future, when posting a photo, check the "store original" box to the left of the "add attachment" box and we can make the photos larger to see better as well as see what camera and settings were used.
Check your private messages, I sent one to show you how it would look with different exposure.
Delete the #2 folder (try to do it in camera) then reformat (in camera) and see if another folder is produced but, as mentioned, if you shoot more than 1,000 photos, another folder will be produced by the camera.
Watch Steve Perry from Backcountry's review. It goes along with Tony and Chelsea's review. For action photography, the focus is too slow (on the pre-production models) and he brought up a few other interesting points. For still photography, everybody loves it, not so much for action photography.https://www.youtube.com/watch?v=jMTtAi5oPoo
As long as there is greed/want for "more" (and camera companies that need to outdo their competitors, and keep those greedy people buying new camera's), the camera tech will continue to evolve. The ability to take "more" excellent quality photos may increase do to faster sensors and bigger buffers, but as many here have said, a 70 year old camera in knowledgeable photographers hand will still be able to take the same quality photo as the newest "tech" will.
Most don't need "more" but those that take action photos would love to see 60-100 FPS at 50+ mega pixels for 10-20 seconds at 50-100 ISO.
