Of course an engineer would not care about an old photo of my cat. But there are millions of photos at stake here, taken by many thousands of photographers over many years.
> he fact is that support for old and/or obscure file formats is regularly dropped from new versions of all software
Hmm, do you have any examples of image formats that have been dropped by popular software packages? I am not aware that Photoshop has dropped support for any formats, for example. And Graphic Converter has been around forever, it now supports import of 200 formats and they just keep adding to it.
It has an amazing range of functions for managing and manipulating images. It will play GIF animations and it supports keywords. (There's an entry for it in the manual. I haven't used keywords myself.)
You can download a fully functional copy free of charge but after 30 days it has a 30-second delay between launching and operating.
Try Graphic Converter, it is made for converting from one format to another. I think it asks you to pay, but you can use it for free. I think.
iLife '08 (containing iPhoto 7.0) was the last version that will run on that Mac mini, assuming it has enough RAM (but it probably doesn't).
iPhoto 7 is more similar to the current version than the previous ones since it introduced Events. It will probably be shockingly slow on a G4. iPhoto was always sluggish on every PPC Mac.
You should also try GraphicConverter. Try both, but the older version might run better. http://www.lemkesoft.com/xd/public/content/index._cGlkPTM0NA_.html
Some googling found a forum thread where a commenter had success with Graphic Converter. Not on multiple monitors at the moment so can't try for myself.
In this case, no. I was using GraphicConverter. I haven't learned Photoshop very well yet. I'm working on that with an image of M42, using layer masks to bring out detail in the core while retaining the extremities.
Graphic Converter will browse your iPhone for photos. It will open my .nef photos from my Nikon and my RAW photos from my Canon, so I expect you can edit your photos in it as well as browse your iPhone and copy the photos over to your desktop Mac. It's forty bucks US.
These were made with a Stenoflex cardboard pinhole camera, scanned grayscale with an Epson scanner, and then inverted with Graphic Converter.
I guess I'm pleased with the result as this is my first attempt at pinholing... but I would like to know what I'm doing wrong. Too long on the exposure maybe?
