What is your largest image file straight from the camera?

I've noticed that image files can greatly vary in size from taking a photo of a blank wall to a complex subject. On my camera the largest RAW file I've taken is 39MB, it's a photo of a A/C unit outside my workplace. I zoomed up close to test the focus of the lens filling the frame with the many small fins of the unit.

So now I'm wondering what could be bigger than that? My usual RAW files are about 25MB.

Both of these are from the 5d MkII. The top shot is 39,417 Kb, but there is an good excuse for that: ISO 25600, and all the noise that comes with that. Funny, though, it is counterintuitive that a noisy image would affect the file size of a non-compressed file format. I just assumed the same depth of data for each pixel, regardless of whats in the next pixel.

The second shot, the one of the ivy on the overexposed wall was shot at a much more reasonable ISO 400. It weighs in at an inexplicable 35,769! Seem like a lot of white wall for so much data. Go figure.

On an unrelated note, your location makes the second time today I heard of Fremont. I saw that Washington Hospital in Fremont has my job (Nuclear Medicine Tech - a form of X-Ray) posted for $55.35 per hour to start. Not too shabby for Jr college and a 9 month certificate! My wife, who has a Masters - well, stuff like this drives her friggen crazy! But I did print that out for my boss - just so she knows what the going rate is!

Raw does actually have lossless compression, which is why added detail such as noise increases the file size.

As for the second image, the reason it's so big is because of the exposure. If you read "expose to the right", you'll find that tones located in top 1/5th of of the histogram may contain roughly half of all the available data from a typical camera sensor. I can shoot a flat subject with plenty of detail, for example, and the filesize can vary as much as 27mb~32mb depending on the exposure.

Edit: Just shot some textured wallpaper at ISO25,600, f/8, 1/200th and almost over-exposed the shot, got 45mb... there you go.

I wonder if you can get past the 40MB size? (edit, just re-read the posting above me, interesting!)

My friend works for Washington in Fremont as a RN, he really likes it. Their campus is pretty big, just in the past few years took over another site. My only experience with Washington is their ER which was staffed with good people, including a friendly x-ray tech. lol I broke my clavical and asked about his job, started to tell me everything including what bugs him.

Palo Alto Medical and Kaiser is also in Fremont, they are the other major health care companies.

I crashed on my bike out a dirt jump, slammed my right shoulder into the next jump. Wearing a full face helmet, the lower part pushed into my clavical and it snapped like a twig. Sounded like someone broken a chop stick next to my ear when it happened.

A few years back I broke my clavicle in your neighborhood. On Calaveras Road. I was on my BSA special. One lane road and a drunk driver came around the corner and hit me head-on. And took off.

I was lucky it was just a clavicle.

The bike was bent up but it's fine now:

I ridden Calaveras many times on my old motorcycles, it's extremely dangerous especially during the weekdays. Commuiters trying to beat the freeway traffic driving fast and cutting corners very sharp, mix in blind turns, makes for a bad road during the South end.

Good thing you got off lucky, place is almost as bad as Mines Road.

BTW love the number 6 reference.

Actually, I like Mines. It's much wider except in just a couple of spots. I think Calaveras is much more dangerous, literally one lane over much of its length.

Heh. Not many people remember any more.
