File Sizes for high res pics: Nikon 5700

Archived from groups: rec.photo.digital (More info?)

A friend of mine has a Nikon 5700 and the file sizes when the camera is set
on 5mp are only 1.3mb for jpegs, even when it's set on "fine" resolution. I
would have expected a file size of over 2mb. I would be grateful if anyone
could tell me what file size you should expect for jpegs on the highest
resolution of the 5700. If the file size is in fact over 2mb, are there any
settings that my friend should alter so that the full resolution can be
achieved? Thanks very much for your help.

Regards, Fred

That's been my experience.

Hi Harvey...

I have a tool here called jpeg quality that measures
the level of compression in a jpeg.

I got it from mediachance (www.mediachance.com); but I just
checked quickly and it doesn't seem to be there anymore.

It was freeware; I have a copy here, and I'll be glad to
email it to you if you like. Send me an email; I'll reply.

Take care.

Ken

Sorry, brain fade at work on this original reply. 1.2MB was around normal
for my 990. 1.6-1.8MB is about what I got with my 5700. It will depend on
the settings for sharpness, saturation, contrast, etc.

Of course. Every manufacturer uses differing amounts of compression in
their settings.

However, I have

I got pretty good 8x10" from my 990, so yes the 5700 is better. It would
help to know what settings you are using for the in camera processing
settings. IMO, for best results set all of these to none, ie sharpening,
contrast, brightness, etc. In fact there was a movement by some 5700 users
to set lower than standard saturation. Of course all the above means one
them does have to process every image you want. For best work of course,
raw is the best. Unfortunately, Nikon never offered a firmware upgrade that
addressed the issue of the lack of speed of saving these. Expect 20-22 sec,
no matter how fast a card is in the camera.
