Rules for Posting Guides on Our Community
1. Defining a Guide Guides are comprehensive reference materials, how-tos, or comparison tables. A guide must be well-organized both in content and layout. Information should be easily accessible without unnecessary navigation. Guides can include flowcharts, step-by-step instructions, or visual references that compare different elements side by side.
2. Infographic Guidelines Infographics are permitted if they are educational and informative. They should aim to convey complex information visually and clearly. However, infographics that primarily serve as visual essays without structured guidance will be subject to removal.
3. Grey Area Moderators may use discretion when deciding to remove posts. If in doubt, message us or use downvotes for content you find inappropriate.
4. Source Attribution If you know the original source of a guide, share it in the comments to credit the creators.
5. Diverse Content To keep our community engaging, avoid saturating the feed with similar topics. Excessive posts on a single topic may be moderated to maintain diversity.
6. Verify in Comments Always check the comments for additional insights or corrections. Moderators rely on community expertise for accuracy.

I was going to say, they began moving away from mirrors a long time ago?
Plus, this is how a digital reflex camera works.
More precisely, there are now basically no cameras with mirrors anymore.
There are still DSLRs and I think they are still being made but I‘m not a 100% sure
Yep, they are still being made, both Canon and Nikon are still making new DSLRs
As far as I know the 1DXIII is still being produced, nearly 4 and a half years after its launch.
Single lens reflexes have one massive advantage: the sensor is not being used while you're composing or idle, which means the sensor doesn't heat up as much. Hot sensors generate noise, which you then have to compensate for (by doing an equal exposure with the shutter closed to remove the hot pixels).
But mirrorless is faster, cheaper to produce, smaller. It's inevitable that DSLRs will soon be a relic of the past. But they won't be for a while: 30% of the enthusiast market in 2022 was still DSLRs.

The other big advantage is much better battery life.
Here's a great interactive guide to how cameras work. Pretty much every graphic on the page is interactive. https://ciechanow.ski/cameras-and-lenses/
"The mirror flips up, and the shutter opens"
THAT'S WHY IT GOES DARK IN THE VIEWER WHEN YOU TAKE THE PICTURE.
Honestly, I have no idea how I didn't realize this, but I always thought it was the shutter closing during a photo that caused it to go dark. No idea why I thought that, because it doesn't make any sense.
I feel like this type of guides are only understood by people who already know how different camera settings affect the picture quality. As a such person it's really difficult to imagine myself in the place of a total novice but I can imagine this not being helpful at all.
I like Aperture Science!
