Macro and Micro are both used in photography.
Macro generally is when a lens will reproduce an object the same size on film/sensor as it is in life.
Micro is for smaller subjects at higher magnifications such as using a microscope.

!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Macro generally is when a lens will reproduce an object the same size on film/sensor as it is in life.
Hey that's pretty cool. Is it really what happens?
Yep, most macro lenses such as the 90 to 105 range from Sigma, Canon, Nikon and their ilk tend to have a designation like 1:1 in the description.
This is normally based on a 35mm frame size, for cropped sensors the magnification is greater.
Actually for cropped sensors it'll still be 1:1 but "cropped"
You can get more magnification if you use extension tubes or specialized lenses.
Cropped by way of a smaller sensor, but magnified if you compare a "full frame sensor" camera and a "crop sensor" camera with identical pixel counts. A penny will have a penny-sized projection on the sensor, but the image from the crop sensor will have ~40% more pixels of the penny.
Depends, I think. In the same order of magnitude definitely.
Edit: this makes me wonder, is it possible to get an orthographic perspective with an ordinary size (but maybe not standard) lens on a normal camera?
I suppose tilt shift lenses can achieve that.
No, tilt-shift doesn't have any bearing on whether it's focal-length is high-enough to make the magnification 1:1..
hth!

As an aside, a "slow motion camera" and a "high speed camera" are understood to be the same object, being a camera that can capture at high frame rates, to slow down apparent motion in the video output.
Which is fine, because the opposite is a time lapse camera.
Two train of thoughts. Making something 1:1 ratio is a true "macro" lens for photography. Because you're increasing the size of the object to match the size of the sensor.
Then you got microscopes which makes things much larger than life.
For which manufactures call it what? Probably all marketing, but this makes the most sense in my life for justification.
Also Micro lenses are also used for marketing for CCD and CMOS sensors.
To add further confusion, I'm not sure if it's still the case, Nikon used to brand their macro lenses as Micro Nikkor.
A macro lens produces a large image. It's a bit silly but I guess once these things get a name it's hard to get it changed.
