comment Raw vs Jpeg for non-professional use
"So verbose in your precision" Unlike yourself, posting by far the longest answer so far? :)

comment Raw vs Jpeg for non-professional use
"...all the data the sensor gathered in glorious uncompressed format." Make that "possibly compressed losslessly" rather than "uncompressed". Simple test: if the raw data was uncompressed, then all raw files from the same camera would be approximately the same size (since the JPEG preview image accounts for a small fraction of the overall file size). Since raw file sizes can vary wildly even from a single camera, we can conclude that they are unlikely to be uncompressed. Since the whole point of RAW is to preserve all data, we can conclude that the storage is likely lossless.

@Martin By the time you reach into the tens of gigabytes, but less than terabytes, it doesn't really make a lot of difference how much data you're looking at as far as backups are concerned. For most, at that point, external HDDs are the way to go these days. Optical media doesn't have the per-disk capacity and rewrite capabilities, and tape with that sort of capacity is expensive, as well as being a specialty medium. A pair of USB3 or eSATA external HDDs will almost certainly be the most practical backup approach for most situations.

comment Is modifying a photo to educate generally fair use?
What is your location? What is the location of the photographer? Legal matters differ between locales, and "fair use" is a legal principle.

comment Should I store unedited/raw, edited, or watermarked images while backing up on DVD/CD?
@ths What are you going to use to run that copy of Lightroom in the emulator? If you say any version N of Windows where N >= WinXP, how do you intend to activate the operating system? Come to think of it, doesn't Lightroom also require product activation? While Adobe may cooperate now, will they still do it in three decades? Will Adobe be around in three decades' time?

@ChrisH Beware of saying "indefinitely" to anyone who thinks like an archivist: like "forever", it's a really long time. And if there are large-scale changes to the software, functionality may be dropped because it is not deemed worth the effort to transition it to the new situation. PCX images were once fairly common, but if there is major rework to for example GIMP for some reason, will the contributors feel that PCX support is important enough to spend time on? How often do you encounter PCX images in the wild these days? I know I very rarely do.

OP explicitly said storing the backup on DVD/CD, not HDD.

comment Are there any downsides to scaling down unsharp images?
That £60 2TB HDD won't work indefinitely, however, and will eventually need to be replaced to keep serving its purpose of providing reliable storage. So the single purchase won't really let you keep the photos "for ever". Not really arguing with the point you're making, just pointing out that "for ever" is a fairly long while.

comment How should I respond to a lowball offer for commercial use of one of my photographs?
"I give a price. If they immediately come with an unfair response, I increase the price e.g. 10% or more." Do you mean that your price goes up compared to your original offer, if the customer tries to lowball your offer enough that you consider their counteroffer "unfair"?

comment Why does increasing sensor size necessarily lead to lower silicon wafer utilization?
It wasn't entirely easy picking the answer to this question to accept. I liked both yours and TFuto's, but ended up accepting TFuto's because it gave a handful of concrete reasons, and upvoted this one. This answer would be even better if you incorporated that last comment into the answer itself, IMO.

Out of curiosity, who are the "we" in the last paragraph?

I don't really get it. I can understand why it'd make a difference making a completely different device, but are smaller sensors really that different from larger ones?

"There's not another 24mm x 36mm spot anywhere on that wafer to make an additional sensor," Well, that's where the "smaller ones" part of my question comes from.
