S200EXR: Incredibily HUGE Dynamic Range.

[cassano]

Today, I gave s200exr a tough DR test.

3pm, afternoon, very sunny outside . In my room, only one window. No artificial light was on. No flash. Point my lens towards the window, gave it a shot.

EXR DR mode. ISO200. *

This is the first picture, delivered by s7RAW, 0EV compensation. No PP.*





Now, this one was convered by FinePix Studio. PP by window Live photo gallery. No fancy operations. Just adjust curve, reduce noise a little.





Totally impressive. I have to say the lighting condition was the worst that one can imagine. The second picture is just unbelievable, in terms of DR. Colorwise, it is generally good, except that the window on opposite side shouldn't look so purple/blue.

Comments are welcome.

... Looks very good.

DR is certainly one thing that the Fuji's do extremely well. Particularly, since the introduction of the S100 fs, and continuing with the EXR series.

The new HS-10 is only a fraction behind them, but also does very well.

Enjoy the camera.

Cheers.

Yep, the EXR sensor is awesome in terms of dynamic range. It is hard to beat.

Lloydy claims that the HS-10 is just as good. But provides no images to support that claim.

 

[cassano]

To give you guys a sense how bad the lighting was, here is a jpg file, converted from s7raw, with -4 EV





Even this cannot help to rescue the highlights.

 

[cassano]

Yes. I knew S200exr is excellent in term of DR. But I never expected it can holds both shadow and highlight information in such an extremely contrasty scene.

If you check the histogram of the first photo delivered by s7raw, it has a very deep U shape. I guess in this scene, there are more than 12EV difference between high & low.

... In fact I have said the opposite.

Please don't just repeat statements others made, about what I said, which I didn't say. Too much of that nonsense here, at the moment

Well, in another post you did make that claim. I even typed up a response to it but canceled it because it was not well written and I did not have time to correct it.

The EXR sensor's most impressive feature is that it can take 2 pictures with different exposures at the same instant (hence the output picture has half the resolution in EXR modes) due to the doubled pixel arrangement.

I have read somewhere (which means it could be an urban myth of course) that one set of pixels takes an exposure at a quarter of the 'shutter speed' of the other set - hence it captures lots more detail in the highlights.

Is the EXR sensor the only one out there that has this double exposure feature?

Shame it can't do the high speed batch capture of the Sony sensor in the HS10 but I'm looking forward to a 20MP+ version on a decent sized bit of silicon!

 

[peter42y]

impressive.

 

[OnTheWeb]

No. There are many other cameras that combine 'double exposure' images. Ricoh CX2 and CX3 for sure can do it. Some of the newer Casio's even can do it.

 

[Lilianna]

the difference being the Ricohs take the image sequentially, the Fuji use the binned pixels to take both simultaneously, with obvious advantages for moving subjects.

Great stuff why i love the camera.

There was a post long ago over at Fredmiranda's about the dynamic range of the Fuji S5. The photographer shot a portrait, properly exposed at f/16. He then opened up the aperture, adding exposure at each stop. So he went from f/16 to f/11 and took an image. Then to f/8, took an image. Than to f/5.6, etc all the way to f/2.8.

By the time he got to f/2.8, the image was 95% or more pure white from total over exposure.

Then, in PP'ing, he recovered each and every image. Even to my eyes the f/2.8 image (which is 5 stops over exposed) looked very good. The others were fantastic, and you would never have known that they were so totally over exposed.

The Fuji S5 is on hell of a dynamic range monster.

 

[cassano]

Agree. Also note that the Fuji can take 2 raw files simultaneously, while Ricoh, if takes 2 raw simultaneously, might need considerably more time than taking 2 Jpegs.

In fact, Rocoh's (and some others) idea is essentially the same as "exposure bracketing", except that with high speed continuous shooting, one doesn't need a tripod.

I think the EXR method of exposure is far more elegant than bracketing.

I concur

I agree.
F200 EXR has also an awesome dynamic range.

By the way : The sony HX5V also does merge 2 pictures each one with a diferent exposure.
I hope we will see a F300 EXR but I am not sure about it
