... Following on from my thread, a few days back, about ISO 800 Raw :

http://forums.dpreview.com/forums/read.asp?forum=1012&message=36209555

I dug a little further into my library for images which were shot at ISO 800, Jpeg, Chrome. I also went out and shot some new ones.

Have a look in the second post.

Cheers.

... These are all shot at ISO 800, Jpeg, Chrome. DR is either 100%, or 200%.

They have been processed in ACR, mostly for levels and sharpening. Some have also been cropped/straightened.

PS - The first is a shot looking into the local market.

You can see there is all kinds of weird and wonderful light. Fluorescent, tungsten, unfiltered daylight, blue filtered daylight, etc. I shot many here as it is a good place to test out high(er) ISO's.

I wanted to view them as normal people would (on a slideshow on the computer), so I downloaded them to do the same. While they might look pretty ok here (I could get my D5000 ISO6400 images looking exceptional at these sizes)...they looked real bad on my 15" MacBook pro on a slideshow.

I guess that is where at least 99% of the people will probably want to use them/see them. And I can't tell what's the main culprit....the NR from the camera, or because the small images are getting upsized or zoomed in bigger to fit the display for the slideshow so they appear very blotchy.

Maybe you should upload them to at least 1600 pixels wide to cover up to 17" monitors if you are trying to show people what the camera is doing under real usage. I think that might be the purpose of your post...no?

Hi Stephen,

I think no one can say what 99% of users really do with their pics - except we can find a quoteable study about that.

Thinking about my relatives I would say they do small prints maybe for greeting cards. Or sending the pics via email, but then downsized to reduce the volumina. Most of the persons I know would say at a LCD-TV-show "what a nice flower" and would not notice any difference between a noisy 800 shot and a clear 100 one. How many people have a well balanced screen - or photographers eyes?

On the other hand, this is a forum for photographers and, yes, to see what a camera can do, the size does matter.

These are ISO 800 shots I have done with the HS10 (close-up-lens) a while ago and already posted.

The first one as it is, the second is a pano from 2x24 mm raws, ISO 800, f 2.8, 1/15 (handheld) and downsized a bit.

Dave, I like your shots, the colours and the fact that a compact like the HS10 is doing well in low light. Well enough for presenting them in most of web forums and well enough by far for showing them to friends and relatives ;-)

Regards
Nic

Nictita...of course I can say that. It's common sense and we don't need some survey. We buy a camera to view images....no? So how do we view images? Two ways (mostly). You can either view them on print or on a monitor. That would equate for 99% of people useage, no problem.

And for the smallest common print (6x4) and for viewing on a small monitor, you will need a image with 1600 pixels wide....which is exactly what I asked Dave to produce or else I don't see the point of his thread.
Thinking about my relatives I would say they do small prints maybe for greeting cards. Or sending the pics via email, but then downsized to reduce the volumina.
There you go. You just supported my claim with that example. You will need at least an image of 1600 pixels wide for a small print or to share with friends for them to view properly. You relatives fall under my 99% estimation.
Most of the persons I know would say at a LCD-TV-show "what a nice flower" and would not notice any difference between a noisy 800 shot and a clear 100 one. How many people have a well balanced screen - or photographers eyes?
But you will know. That is what matters. It's you who spent the money on the camera....not your friends. And it is mostly you who will end up with the images on your computer for your own personal memories/viewing in years ahead.....and you will know a crappy ISO800 shot from a decent ISO100 shot. That's the bottom line. If its not....sure you might as well use an iPhone if that's the case!! What's the point in buying a camera at all, so?

I can only speak for myself. I do share my images with others too. And those people wouldn't be as photo savy as me....but at the end of the day they still remain in my possession for my memories too, and I have to look at them more than them and with a more trained eye. And believe me, I have often wished that some of my old holiday shots from places were I can't visit again, were taken with a better quality camera than what I had with me then.

For many years on holidays, I always left my DSLR at home and brought a P&S. I used to convince myself that the bulk was too much to carry because I travelled by motorbike. This year I took my D5000 and 16-85VR and the results were light years ahead of any P&S that I have used in the past. And even the novices noticed. And I wasn't too troubled by the bulk either. It was all in the mind! A selection from the last holiday:





















































...and believe me, I would tell a ISO3200 shot from the D5000 from the HS10 a mile away and probably my friends too.

I think that was the whole point of my response. Most people want to pixel peep at 100% level to see what's going on. I wasn't even looking for that. I just wanted to view them normally on a monitor with no enlargement at all. I couldn't do that. So what's the point in posting web size images unless you are either trying to hide something, or are trying to overexaggerate the performance of what the HS10 can do, or perhaps the author of the thread wants to get some kind of "feel good factor" knowing that there are plenty of people here who are oblivious to the fact that these are not a representation of the final image for general purpose use, and who will respond to the OP with a attaboy response.
These are ISO 800 shots I have done with the HS10 (close-up-lens) a while ago and already posted.

Thanks Nictita. Now these are a decent level to see what the HS10 does at ISO800. Sorry and no offence.....the subjects are nice and you photo skills are pretty good, but all I can say about the technical quality of these results is that you are lucky you have people who don't know ISO800 from ISO100. ;)

Thanks Dave and that's more like it!!

Now we can see what we will see when you view them on a monitor or do a small print. And the results are a stark contrast to the earlier ones which looked more dandy!

Without even looking for 100% crops....I can tell straight off that I'd only use this setting in an emergency on this camera. Every image here is way too soft and lacking a bit of bite and texture. This is unusual for your images, as they are usually a bit oversharpened to say the least. This gives me the feeling that there was a lot going on under the bonnet to keep the noise down on the raw files. So much so that some have a plastic look to some of them. Also, not one of the images have any pronounced detail in any of the subjects hair. I wouldn't even dream of going into lower lighting like 1/4s to 1/10s. These are struggling at 1/40s to 1/50s....sadly not enough even to give you non flash shots at a european household with tungsten lighting. :(

So that is about what I can see what the HS10 is doing from your images. Weather they are acceptable to people expections is another matter....certainly they wouldn't meet my modest expectations even as a novice. Anyway, don't take offence of my findings and thanks for posting. This is not a personal reflection on you own photographic skills, but more a reflection of the technical abiliities of your camera at that particular ISO.

Once again I truly do enjoy this series, too. You seem to have taken some reallly love images with your HS10. They look just fine on my monitor here which is a 30 inch samsung. Colors and sharpness, exposure all appear right on the money. Many thanks for sharing these.

I bet they are not displayed fully across the whole width of your monitor. Dave stated himself that the larger sizes he posted (1600 pixels wide) only covers the full length of about a 17 inch monitor which is pushing it. His images are 1600 pixels wide which is the resolution of my 15 inch monitor. So I find it hard to believe that images of only 1600 pixels wide can display across (what must be about) a 3200 pixel monitor without looking rubbish. The images will have to be seriously zoomed up to cover the whole screen on your monitor. It would be like looking at the images at about 150% if displayed across the complete area of your monitor.

Yes, color saturation is OK as it should be at ISO800. And exposure is in general, OK too. But the shots are are all about noise and noise reduction. Sharpness is certainly not right on the money due to excessive NR.
  • Shot 1: The woman's face and hair is soft.
  • Shot 2: everything on shot 2 is soft....the beads around neck, the signs, the face...everything.
  • Shot 3: Again, all the main stuff is soft here...the foreground in front of the lady, the lady's face and hair.
  • Shot 4: Only thing sharp here is the shop sign in the background. All the main stuff is soft here again....all the peoples hair/faces, the main fruit in the foreground lacks bite.
Maybe we have a difference in opinion as what we perceive as sharp. This is what I would call sharp and detailed to me....give it the "two click job" to enlarge to same level as Dave's shots:

Of course it depends on the on the pixel setting of the monitor. I am using currently just 800 x 600 and still his images appear fine here for me.

I see no reason to change my monitor settings unless I need further resolution which I do not.

I still maintain Lloydy's images appear just fine from here full screen @ the resolution settings mentioned above.

Sorry I did not bother to look at your images here because I am only interested in Lloydy's images in his thread. Thanks anyway.
 
I hear you 100% on the HS10. I know it does not have the very high Resolution of the F100. But you, are making the HS10 sing at least for me viewing your images from it. Not to forget how well Silent Oracle is doing with her HS10. Some of the finest bird shot she has produced that I have ever seen no matter the sensor size.

Kind regards, Gary N W SFO
