I'm a techie and when attending various training presentations, I'll take a photo of a slide that is being presented.
Now I want to save this training slide for posterity.
What resolution is adequate for storing a training slide long term. The goal is that I should be able to
read it, copy it to a MS Word document when creating a document that summarizes the event, or print it so I could read it.
My gut feeling is to use 800x600 but I have no technical basis for this.
I know there are a lot of factors that go into this. In one case, I'm attending a
music lecture which highlights
musical notation, in another lecture it's highlighting a
I'm not looking for perfect. I'm looking for an answer where 5 years from now I'll be happy with having information from a lecture that I attended and took notes but didn't put them into a MS Word document.
At this time, I'm resizing (in place) images using LightRoom and Photoshop so once I've resized them (in place) I can't go back to the original image.
A related question has to do with the resolution. I notice that the pictures I have taken are 240 pixels/inch. If I simply change the resolution to 120, the image size drops considerably. In one example,
3024 x 4032 @ 240 pixels/inch, 68.8M 1512 x 2016 @ 120 pixels/inch, 17.4M
Is it better to change the image size, and keep the resolution, change the resolution or change both. In general, I'm going to be viewing data on the computer (not printing). I realize for prints, you want to maintain a much higher resolution.
