Today’s top of the line sensors hit 100mp. The Fujifilm version is even”affordable”.
So how many mps will they be able to reach? I think that based on everything electronic that I’ve seen, gp sensors might be reachable. Maybe within 15 years, maybe shorter.
But…
Will the lenses be able to keep up? What about the screens? Will they be able to resolve all the information in the photo? Will there be printers that can do the photos justice?
I’m sure that the external drives will be up to the task.
How about the computers themselves? The speed they’ll need. The RAM. The graphics card. The software (PS gigapixel anyone?)
Will our eyes be able to resolve the difference between say a 100mp photo and a 1gp photo?
What will such a setup be used for? The difference in information collected will be enormous.
You won’t need long or zoom lenses.

I ended up working all-day Friday – heading home, the news talked about this historic geomagnetic storm that will make for a beautiful display in night skies across the country. When I got home, I told my amazing (and understanding) wife, load up, because we’re headed to Crater Lake. Around 4-hours later (as the sun was setting), we’re setting up cameras and waited for the light show of the decade (maybe the century). Around 2:00 am, we’re loading up and heading back to home.

Was it worth it, I would have to say “Most Definitely”.
