Well, I use a MacBook Pro with OS 10.14.6 and Lightroom Classic (the latest version with the subscription) works great.

There are actually two parts of Saguaro National Park, one is East of Tuscon and the other is West of Tuscon. I would recommend the one West of Tuscon because it's near Old Tuscon (a movie lot) and the Arizona-Sonora Desert Museum (which is also a zoo).

A couple of other things, many on your way back if you take I-10, Benson is a small town you pass by on I-10. Tombstone is only about 25 miles south of the interstate and is an interesting visit. Also near Benson is Katchner Caverns, certainly worth a trip and a tour (no cameras or cell phones allowed in the Cavern unless you are on a specific Photo tour that only happens about once a month).

Did you rotate the image, or when you exported the image to 2000X3000 did you have the 2000 in the right place (i.e. horizontal factor). I ask because I noticed that the 2000X3000 is exactly the right ratio ad 2000X 1333 is exactly the same ratio. It just makes me think that you put the number in the wrong place in your software.

No problem, I forgot the milli in front of amps! My bad!

22000 milliamp-hours is the same as 22 amp-hours!

No I did not disconnect the RV battery. BUT, before I connected the jumper, I tried to start the vehicle. Turning the ignition on, no dash lights were lit, there was no enough voltage for anything to turn on. I didn't even bother to check the voltage on the battery. But I hooked up the charger (very compact and relatively light) the engine cranked right away abd the engine started within about 2 seconds! That was impressive.

I doubt the started motor was just pulling 22 amps, that's low for a starter. The figure of 22000 amp-hours should be the capacity of the battery for putting out 22 amps for 1 hour, or 44 amps for 30 minutes, or 1 amp for 22 hours. It does not mean it is limited to 22 amps.

20 amps at 5 volts is 100 watts, you just forget to add the second zero.

I recently purchased a battery powered jump starter. It's rated at 22000 ma-hours and has a Lithum-ion battery. I wondered if it would have the current to jump start my RV with a V-10. It certainly does, I've used it twice and it started perfectly.

It's amazing what technology has been able to do!

I have a Nikon, not a Canon, but I suspect their policies are similar on shipping costs. I sent a Nikon lens, under warrenty, because the auto focus quit working. I paid for the shipping to the Nikon Warranty facility on the West Coast. I wasn't paid for the shipping cost by Nikon. Nikon repaired it under warranty and shipped it back to me at no cost. I cannot complain about the service I received, nor can I complain about the cost (maybe $30 for shipping, packaging, and insurance).

Don't feel bad. The way Adobe renamed their two Lightroom products has caused many problems for Many people. They went from Lightroom Mobile and Lightroom to Lightroom Cloud and Lightroom Classic. That has caused many people some issues. I hope it caused Adobe a lot of migraines.

I don't know what computer you are using or what email program you are using. On a Mac, if you attach a jpg file, it will generally show up in the email. However, there is also a paper clip icon. If you click on the paper click you can download the jpg attachment. On a Mac, the jpg attachment is also rendered as a photo in the email.

I don't know is Microsoft does the same think.

Since you are using a MAC, use Time Machine for backups, you can specify what files to back up. It is a sequential backup so it only adds new files to your backup.

I suspect you are talking about Time Machine. It's an Apple Program that is part of the operating system. All I will say is that I have used it for years and it works great.

First, I would recommend that you don't believe everything you are told. Investigate yourself, get second and third opinions. There are subjects where a full frame camera can be better than a crop frame, and there are other subjects where a crop sensor is better than a full frame.

Ask questions, get opinions, and make your own decision.

Understand all the differences between a full frame and a crop sensor camera. Understand the cost differential, understand all the advantages and disadvantages, and you make the decision.

When I started getting involved in Birding, it was 2013, and I was at the Salton Sea in California. My camera was a Bridge Camera, a Konica Minolta Z-6 I think. That is kind of an extreme Crop Sensor Camera. Because of the issues I was having, I went to Costco near Indio CA and bought a crop sensor Nikon DSLR and wow, it made a surprising difference. The cost was about $800 with two lenses (18-55mm, and 55-300mm), plus a few other items. If I had gone to a Full Frame Camera, I would have spent 3 or more times as much. I am still happy with my decision and have had several photographs used for various commercial purposes.

Now, which is better Full Frame or Crop Sensor? It depends! I think for Birding (and cost) a Crop Sensor makes more sense. If I were a professional Portrait Photographer perhaps full frame MAY have an advantage.

Do your research, consider what you are interested in capturing, consider your budget, and make an intelligent decision.

Is there a question?

A Crop Sensor Camera (like the 7500) is a really good choice for Birding. I haven't used a 150-600 mm lens but the focal length, especially on the 7500 should be great.

Photoshop Elements is an excellent program. I have used several different versions. Adobe seems to release updated versions every Fall. The new versions always have some improvements. I think the new versions are about $80 or $90.

Photoshop Elements doesn't do everything Photoshop does, but what it does do (quite a lot) is excellent. The last version I used was probably purchased about 10 years ago. I won't try to describe the latest versions since in 2013 I went to the Lightroom/Photoshop subscription. That may not be right for everyone, but it has worked well for me.
