It’s been done for Sony cameras a while back. One of the tools that lets you get into the camera’s firmware is Sony-PMCA-RE. As far as I know this is not the only one either.
It’s not a powerful as a Magic Lantern, but that’s not the point, which is that camera firmware hacks are still going on.
As long as there is a reason and motivation someone will figure it out.
Someone will crack the firmware and offer a hacked version shortly after this rolls out.
I would never use Instagram for any sort of serious question or conversation.
Do the legwork to at least get their actual emails and contact directly with a personal message/letter that shows you know something about them, are serious, and are asking a genuine question without any sort of expectation that they owe you anything.
Instagram is essentially a spam generator.
And on Instagram of all places. At least do the legwork to track down an email and contact them directly and personally instead of via a medium that’s essentially a spam generator.
I'm no expert, but I don't think the can actually do that.
If it's their account, yeah, that makes perfect sense, but on your own personal account that's not affiliated with the company? Not sure if that's ok.
If you're taking your own photos during work hours, on a job, or ones that show the business in some way, then they have some reason for oversight, but other than that it's a pretty questionable thing.
One of the ones I've gotten pretty often that makes me laugh is when I'm contacted by someone putting together a TV show (usually a documentary/nature show of some sort) to ask about using photos, maps, or videos of mine.
I always respond something along the lines of, "Sure, let's talk about a licensing fee." Often there is silence after that. If they do contine I'll let them know what I've received for use in other TV shows for a non-exclusive licensing fee, and offer to let them see a copy of previous contracts. Again, the most usual response is silence.
A small portion follow up and we can finally have a serious conversation.
People want free stuff, and if they can't get it for free they'll generally either sulk or steal it.
Watermarks have been easy to remove for a long time now.
If someone really wants to steal your image they will and there isn’t anything high can do to prevent it other than never let anyone see your images, which defeats the point of taking photos in the first place.
Depends on what I'm doing.
For fieldwork and most wildlife 200-600mm
for up close things and macro 70mm macro (although I have a 105mm on order and that may well wind up being my favorite for macro)
For travel 18-200mm
There isn't one single lens, but the 200-600 is pretty much always on my full frame, and the 70mm macro is almost always on my aps-c. For travel it's usually the aps-c with the 18-200mm.
If I had more money my answers might be different.
It’s pretty much the only thing I use. Instagram is terrible, but Flickr has remained pretty damned good.
