s100fs: shooting smaller resolution makes images better?
-- hide signature --

I was wondering, does images become better when you shoot in a lower resolution then the full resolution??
Or does it has no influence on the results?

thanks

Re: s100fs: shooting smaller resolution makes images better?

No. Its almost always better to down sample from the best quality image using software.

When comparing the modes, also pay attention to pixels per byte ratio. A lower number generally means a lower compression ratio and generally better "quality" compared to a JPG of ther same size ( or nearly so ) with a higher ratio. This effect varies with the resolution selected. Higher resolutions can be compressed to a higher degree because of the decrease in small scale visual complexity.

Unfortunately, your table is correct.

I wonder why Fuji is so perverse.

Why the hell 2x3 in Normal quality only?

Pure wickedness?

I noticed this absurdity only after I bought my S100 and I am very disappointed.

S100FS is a wonderful camera! Please tolerate my complaint.

while I agree that they are being capricious ...

... by supporting only 12:1 compression (N) in 3:2 mode, in practice this is still excellent quality. Several have tried (me too) to find significant artifacts by comparing with the same image shot in 6:1 (F) compression, and really have not found anything of note.

You are right, I am not able to see the difference too.

However I think that it becomes significant when resizing, or somehow processing the image. This is why I normally use the "F" compression.

We can resolve that 12:1 is an excellent quality but, without doubt, 6:1 is better.

I'd prefer to be free to independently choose format and quality.

Well, I process my images heavily, and I print them big sometimes. I have F10 images processed very heavily and printed at 12x18 that look great.

6:1 is better.

Yes .... but I have always believed that a difference that makes no difference, is no difference.

Still ... I do shoot 14bit RAW with my D300 nowadays ... for every shot. I just wouldn't get too excited if I had to switch back to 12bit RAW for some reason ... I really doubt it makes much difference with cameras that are compromised by their sensors anyway.

By the way ... can you switch to RAW in 3:2 mode? It strikes me that you probably cannot, since 3:2 is a trick of resizing ...

I'd prefer to be free to independently choose format and quality.

Totally agree ... no reason for Fuji to shut you out, except to save a little work during testing and documentation or something like that ...

WONDERFUL !

One of my long-time hobbies is collecting "sayings" - some from famous people - some proverbs - and some great comments found in real life - like this one of yours.

An all-time favorite is Teddy Roosevelt:

"Do the best you can, with what you have, where you are."

does that cover it, or what?

Another one often used (in my life) is from the Dustin Hoffman flick "Little Big Man" - in which an old Indian Chief gets Hoffman (who was raised by Indians) to help him to a burial ground, where he wills himself to die, being old and tired. The chief lies on his back and composes himself for death, eyes shut. We wait.

After a few minutes it starts to rain on him, and he sits up and resignedly says:

"Sometimes the magic works - and sometimes it doesn't."

This is often applicable in photography - and in software...

Bill, here's what our former Prime Minister said in response at the time to what kind of proof Canada needed to assist in the war in Iraq.

"I don't know....a proof is a proof. What kind of a proof? It's a proof. A proof is a proof, and when you have a good proof, it's because it's proven."

Thanks Bill ... I've used that off and on for years.

Yes ... it absolutely covers every aspect of life perfectly. Over the years I've heard people in software complain all the time that the company wasn't giving enough resources for this or that project, but they have failed to understand the meaning of "do more with less" ... and that saying convey's the proper response to the phenomenon perfectly. Thanks for mentioning it ...

Agreed. You can save a few bucks and get something that works just fine, right up until it fails.

2) Two things are infinite: the universe and human stupidity; and I'm not sure about the the universe. (Einstein)
