Nor would I ever use rice to dry out something like a camera or other electronic item. Oh, I know it works, my Mom always had a teaspoon full of white rice in the saltshaker to keep the salt flowing freely.
What I'd be concerned about is the rice dust. It is very fine and can find its way to the tiniest nooks and crannies.
What I do instead: I have a special jar in the kitchen (away from any food stuffs) that I use to collect all those little packets of dessicant. If and when I should need to dry my camera or anything else, my jar is almost full now!

As an aside, I have wondered if the "crystals" used in flower arrangements, will work as well as a dessicant. I've got three kinds here, one is "polyacrylamide", one is "Sodium Polyacrylate" and one is "a polymer."
They can absorb 200 times their weight in moisture. I'll have to try it out....

One feature you will find in Paintshop Pro as well as in Photoshop CC is support for layers. This allows you to build up modifications to an image and blend them together in various ways. This is a more advanced editing feature that you probably don't need at first - but it is a powerful feature that allows you to edit just an area or two that you specifically want to change.

But there are editors that don't support layers and some are quite powerful. One that I like is called Raw Therapee; it's a free download and there is a good user's manual and user's group for it. Gimp is another free editor that some people like. In fact there are probably dozens of simple that various people will recommend, ranging from very simple (but low in capability) to the more complex but more capable (like Raw Therapee and Gimp).

I notice some strange comments posted that deny reality. For example why attack Academia? The USA has produced over 350 Nobel winners, way more than any other country. Were any not the product of Academia? Who got us to the moon? Where did those scientists and engineers get their training? One could go on a on. Without Academia we would be a back wash. Just because there are some crazy academics on the fringes.....
And the discussions about Liberals and Conservatives. Not long ago there were people called Moderate Republicans and many supported progressive causes. They were often fiscal conservatives but social liberals.

DropBox is designed for large (really large) files over the internet.

However, you have an attendant problem which is not resolved by just getting the file to the recipient.

Viewing it.

TIFF is not one of those browser universal file formats like PNG, JPG, BMP, GIF, etc.

TIFF requires editing or reader software than can view it. Now PS, CC, and the other Adobe products can view it, because they can open TIFF.

There may be a way with the software you are saving to TIFF to embed a viewer along with the file, but by itself the file is worthless to anyone who does not have software that can open TIFF. If you know the recipient can open a TIFF file in the first place, then I suggest you look into Dropbox, or one of the similar large file solutions.

You open a Dropbox account, you upload your big file to Dropbox. Dropbox then allows you to send a Dropbox link (invitation) to the recipient. He/she then goes to Dropbox and downloads the file to their computer.

Dropbox is relatively (????) easy to set up and use. Then, it's just a question of having a viewer or decoder to open TIFF.

I'm going to assume someone is asking you to send a TIFF format, which means they have the capability to open it. If you are the one making the decision, it may be of no value to the recipient if they do not have TIFF capable viewing programs.

NOT ALL editing programs can open TIFF, and surely not basic internet browsers.
