Looking For Tips/Info: Infrared Photography For Inspecting Art

I have a couple of pieces of art that I'm interested in investigating for fun; oil on canvas and oil on board.

I'm curious about what I could pull off with normal consumer-level equipment.

Question 1: If I picked up a full spectrum modified digital camera and a filter that was 950 or 1000 nm, would I be able to reveal anything worthwhile? Reworked areas? Preliminary sketches?

Question 2: I know you want to really hit the pieces with light. Does it matter what type of light e.g. fluorescent, halogen, yada yada yada? Would shining a light from the back of the canvas help at all? Or should you only light from the front?

Question 3: Will there be a difference between what is revealed between the canvas works and the boards? I assume so, but have no clue.

I'm aware that you have to do some processing work in photoshop as well on the IR photos, but that's not really an issue at the moment. I just don't want to waste my time and a couple hundred dollars if I can't get anywhere with consumer tech.

So can anyone answer those questions, give me some tips, or point me in the right direction to learn more about the process?

The ad was paid for by 'Pine Tree Results PAC'.

The PAC has existed for about 15 months and has been given about 12.7 million dollars.

3 million from a sketchy inc. in Texas called Stronger America Inc.

2 million from the ceo of Blackstone

1.5 million from the ceo of Elliot Investment Management- a gigantic firm in Florida

1 million from the ceo of newbalance

1 million from another sketchy inc. in Texas called Lexington Fund (*edit: a poster below said that has ties to the shitbag leonard leo.)

1 million combined from two execs in Reyes Holdings - a massive beverage distributor

500k from John Malone - a billionaire and massive voting shareholder of places like Warner Bros. https://en.wikipedia.org/wiki/John_C._Malone

500k from the founder of Moore Capital Management - a 10 billion dollar company in NYC.

375k from JW Childs & Associates - private equity

350k from the billionaire owner of OBERNDORF ENTERPRISES

250k from a dark money group called CONDORCET INITIATIVE CORP - article about them https://www.publicnow.com/view/A8D70894A72E5E8D6A59DF4C07CD4B2D0D228CE1?1755276441

100k from Palantir

That's ~11.5/12.7 million given by those 12 people/entities.

Another 1.15 million was donations over 2k. (A lot of 100k ones, but I'm too lazy to sift through right now.)

Only 13.5k was from donations under 2k.

The PAC has seemingly gotten $0 from anyone in Maine.

The PAC is run by a guy in Virginia named Koch (I didn't check if there's a relation to the infamous Koch bros.) Here he is and his business.

Scumbags, the lot of 'em.

Don't trust ads. Always check who pays for them. Kthxbai.
