Coin photography camera setups
Cam D:
I think the large files are worth keeping, though for a different purpose. I keep two sizes: an original at ~50MB and a scaled-down version at 20MB. The latter version I upload to my website and compress to use it as the main photos of the coins on my website. The original version I use specifically for my "Ultra Zoom" tool, where people can get the full benefit of my high resolution images without needing to download the entire 50MB file in their browser.
You can see the Ultra Zoom photos here: https://artemis-collection.com/showcase/ultra-zoom/
It uses a plugin called OpenSeaDragon, which is also used by a lot of museums (e.g. British Museum) and even some auction houses (maybe Tauler Fau), and only loads the portion of the image that is visible in the plugin's window and only to the resolution required for the given zoom level. You can see reasonably fine details on the surface of each coin with this tool, more so on smaller coins than larger coins as they're taken at higher magnifications. A lot of these details get obliterated when compressed by 20x so it's nice to have a way of retaining the detail and making it available easily to others. Otherwise my camera setup is a touch overkill ;D
That doesn't mean I can't create a third copy of my images compressed to <2MB but uploading them here means adding another place to manage them and they also can't be viewed to their full potential. I'd likely end up linking the high-res or Ultra Zoom versions anyway as I think coins are fascinating to see up-close and not many others offer this kind of resolution for their coin photos. I can understand the benefits of hosting images on a forum to prevent deadlinks but I created my website partly as a means of getting around file size limits on forums.

Ron and kaleun96,
Ron, I tend to agree, but I have the storage space and I do other kinds of photography (in fact, I actually suck at coin photography, LOL). So, for me, high resolution is just where I am coming from. But, my coin photos probably don't need to be.
That said, kaleun96's site tells me why high resolution is so nice. That is a very nice site and your coins and images are amazing. I also like to see the details, you have done an incredible job, my goodness, some of the zooms are just beautiful. I am going to check this technology out when I get some time. Thanks.
Virgil
Cam D:
Thanks Virgil, appreciate the kind words!

Please do not use quote when responding to the most recent post. It is unnecessary and requires unnecessary scrolling. Quotes are only necessary when responding to an older post to make clear that you are not responding to the most recent post. I have removed many unneeded quotes from this thread.
Virgil H:
I never noticed an issue with quotes on this thread. so I have no idea if I am one of the offenders. I use quotes when I think they are necessary, including when responding to the post just above. Looking back, I think you removed quotes I put in a response intentionally and I really don't appreciate it because you essentially changed my response. Quotes are especially useful with long posts making multiple points and I am responding to specific things in it. Nothing is worse than reading a response where there is no reference to what the response is about. I edit the quotes to leave what I want left. I will say that quotes have never been an issue to me the entire time I have been on this forum. More often than not, I find them helpful. Otherwise, scrolling on by is not a problem. Most comments really require no scrolling at all with or without quotes. But, when I use quotes, it is completely intentional and not out of laziness and it actually takes more time to use them. I actually think it is courteous to use them. This is also the case when responding to multiple points, where I separate the quotes between my responses. I will keep using them when I think it is needed, so delete away. Sorry, you really hit a sore point with me on this one.
