high ISO on a sunny day = lost detail??? (5d & mk III)

You guys are arguing about theory vs results.

The results to the op look better than results he gets at lower ISO.
He sees better overall out of the box results and in underexposed
areas without having to recover that detail by playing with dynamic
range. Why is it better? Because its less post processing for him.
And he, and a few others that agree with him are saying that overall,
ISO 1000 looks better than the same image shot with ISO 100 with the
underexposed areas recovered. How? Who cares, but the op believes
that it was a big enough finding for him to make a thread and post
some results, so that some of the people in this community could
benefit from this info.

That's the point you seem to have missed entirely. No need to be
rude. He doesn't care about the dynamic range he won't have to
recover detail with because its already properly exposed.
thanks michael!

you actually made an excellent point!!

although the ideal exposure settings are mathematically calculated they are still theories simply because the actual shoot has dozens of lighting and other challenges...

and you nailed it!!!

i like my RESULTS by going outside the box... =)

again, thanks a lot!!!

...achieving here other than extended DOF and or higher shutter speed compared to the same images using a lower ISO setting.

If you are using fill flash, I can see the potential benefit of extending your flash range, although it's a balancing act because while higher ISO effectively increases flash 'power,' the resulting smaller apertures progressively diminish it.

the above images were non-flash images... my flash at that time was on my other camera (with wide angle lens)...

BUT i do prefer to use flash (for fill) at all times...

unless my camera is in AI Servo...

and i do agree higher ISO effectively increases flash 'power'... excellent point!!

NM, I have this upcoming shoot and the location might not be ideal as the background is not so interesting. It's time to bring the Beast and shoot at ISO 800-1250 and maybe at f/8-f/11 but still throw off the background. I also want a gritty look to it and at the same token extend the flash range.

Thanks buddy.

...as you've acknowledged otherwise, except where it benefits higher shutter speeds for action or smaller apertures for extended DOF...and the very narrow range of circumstances where increased ISO effectively increases the power of fill flash...there is no real advantage to using high ISO in bright conditions in terms of shadow detail and, in general, dynamic range. In fact, from an academic standpoint, one will have fractionally less DR using ISO 800 outdoors in bright daylight compared to ISO 100.

This is your working preference, and obviously you exploit it well, but it's offers no advantage of technically higher quality images in the majority of situations that don't include fill flash, require faster shutter speeds for freezing action, or benefit from the additional DOF that comes from smaller apertures.

Cheers.

Although higher ISO will increase the sensitivity of your camera to Flash, it also means 1. that you have to use a smaller aperture, hence reducing your Flash exposure anyway,

or

2. Have to use a faster shutter speed, requiring High speed fll (Which loses power with every increase in shutter speed)

Or by staying at sync speed, but then having to resort to 1 above.
 
The results to the op look better than results he gets at lower ISO
How on earth do you want to know that?
He sees better overall out of the box results and in underexposed
areas without having to recover that detail by playing with dynamic
range
What makes you think that?

I asked the OP:
Is high ISO justified in this situation? Could not you increase the
aperture or the shutter?
The answer was
i really like my DR better with my technique... high ISO on any sunny day shoots...
which is as BS as your prattling.

sunny day, between 10 am - 2 pm... outdoor shoot...

low ISO 50 to 200 or high ISO 640 - 1000

many will say shooting high ISO will lose details or "NOT ideal at
all!"

**********************

i've been shooting high ISOs (JPG files) on a sunny day at least 640
even 1000 and so far so good... and instead of talks and
speculations... check out these images...

and please share you experience... about ISO settings on a SUNNY day
outdoor shoot...

for those who use high ISOs please share your thoughts and
experiences... =)

thanks!!!
i have to admit i'm a little confused by this all.

if you need the iso to get a fast shutter to totally freeze things it might get you more detail, but otherwise i'm really not sure how this makes sense

here some ISO200 100% crops, how is my posting these demonstrating anything more than your high ISO crops, I don't get it, you can read the fabric and skin texture in your shots, but you can here too in low ISO shots:



 
i really like my DR better with my technique... high ISO on any sunny
day shoots...
You don't seem to understand much of what you are doing and writing.
Your shots contain lots of blown areas; they may be irrelevant, but
your boosting about the preserved details is amusing.

Of course, if considerations re DoF or subject movement or camera
shake do not allow for a greater exposure, then your ISO selection is
all right. However, it should be clear even for those challenged by
the digital aspects of photography, that the DR of the 5D2 at ISO 800
is about 2/3 stop lower than at ISO 100.

i've tried to adjust the shutter and aperture (on a sunny day
shoot)... and... this is my personal experience and MHO... adjusting
ISO I get better exposure... again, to MY PERSONAL TASTE ...

and i can enhanced my images (especially the darker parts of the
subject) faster without the use of Photoshop Layer...

i'm sharing my findings... it's up to you guys if you want to try it
or not...

but me... i will keep shooting with my setup (high ISO on a sunny day
shoot)...

other photogs LOL... but when i ask them "Have You Tried It Yet??"...
the conversation ends... =(

that in itself, i think is a PURE SPECULATION by the other photogs
who LOL with my high ISO setup... they haven't even tried it yet... =\

but thanks for the basics you shared...

=D
What you're saying makes no sense. Shadow detail or shadow exposure is not improved simply by shooting at higher ISOs. Shadow exposure can be improved by shooting at different exposure settings, but only if the exposure settings are favorable to improving the exposure of the shadows. Exposure, and ISO, whether high or low, are not the same thing.

When you say that shooting at a higher ISO improves the exposure and/or detail of the shadows, you're forgetting the fact that when you chose the higher ISO you also had to change the exposure settings (f-stop and shutter speed), thereby nullifying any advantage in using the higher ISO, except for any advantage you might get with a faster shutter speed for freezing action and/or with a smaller aperture for more depth of field. The overall exposure would be the same. The dynamic range would actually be reduced and the noise would be increased.

When you change the exposure to get more light in the shadows, whether by changing the ISO or the f-stop or shutter speed, you also get more light on the rest of the picture and risk blowing the highlights, which is exactly what has happened in your photos. Even lifting the shadows in post processing risks blowing the highlights unless the highlights are dealt with properly at the same time.

There's no way that simply using higher ISOs improves shadows. It's the EXPOSURE that counts, not the ISO.

Try this: shoot two IDENTICAL pictures, containing shadows and highlights, one at ISO 100 and whatever f-stop and shutter speed are needed to get the right exposure. Shoot the other at ISO 800 and whatever f-stop and shutter speed are needed to get the SAME exposure. Compare them closely. Lift the shadows in post processing. Play with the highlights too. See which photo has the most dynamic range and the most room for adjustments. Post them here, with all the settings/details.
 
That's the point you seem to have missed entirely. No need to be
rude. He doesn't care about the dynamic range he won't have to
recover detail with because its already properly exposed.
That's how I understood the OP from the beginning; he starts with the f-stop and shutter speed he deems necessary, and finds that the highest ISO that doesn't clip away desired highlights is best, which is easily demonstrated to be true both with test shots, and with theory. Some people, however, always have a knack of reading something else than what someone actually wrote, and go off onto tangents based on their own biases and lack of mental flexibility.

Perhaps he was using an unconventional connotation of "DR", but reading the rest of everything he's said, it is pretty obvious that what he meant was that the absolute SNR at his chosen manual exposure is better with the high ISO, which is true (for read noise).

And, IMO, even though the relative read noise is actually higher in std dev at ISOs around 1000 than around 100, the quality of noise is worst at the low end of the ISO range, as a larger percentage of it is banding noise, especially vertical banding, which the RAW data does not have any sufficient blind pixels to help reduce it in conversion.

BTW, you seem to have lost track of the bit-depth threads.

If anyone misunderstood what the OP has said, it's you. He didn't say anything about blind pixels, or all that other gobblydegook you said in your last post. Speaking of going off onto tangents.

Here are some things he did say:

"than using low ISO and underexposing my shots..."

"as i use high ISO, this is my own experience, i get more details, especially the shaded parts of the subject..."

"i have tons of sample images at high ISOs... and i really find the exposure a lot better than manipulating the Exposure Compensation..."

"i don't like low ISOs at the bright sunny shoots...

WHY? the finished photo is really acceptable and decent... BUT my processing took longer... i had to put a layer (for the faces), to brighten up their faces...
with my high ISOs setup... i don't need to layer the shaded areas..."

"- i have better details (or i get better details) on the shaded areas of my subjects... that means i don't have to lighten up the darker areas using photoshop layers... faster enhancement and processing
  • i love the exposure better! even at 1/8000 ss (which many find it so ridiculous... and honestly... i don't know why??!!)... will the 1/8000 ss destroy my camera faster?? why did they even include 1/8000 ss if this is not ideal??... again i love the exposure better than... over/under exposing the image..."
"i really like my DR better with my technique... high ISO on any sunny day shoots..."

"but during day time... with our natural eyes, we can see the details under the shaded parts of the subject... and i really think... the camera should be able to capture those details by setting up our camera the right way... and in my case... high ISO is MY solution...

as i use high ISO, this is my own experience, i get more details, especially the shaded parts of the subject..."

"i have tons of sample images at high ISOs... and i really find the exposure a lot better than manipulating the Exposure Compensation..."

He also brought up details in the shadows as being better when using high ISOs. His main point though, is about exposure and DR and that by using high ISO he gets better exposures and DR.

He didn't say anything about starting "with the f-stop and shutter speed he deems necessary, and finds that the highest ISO that doesn't clip away desired highlights is best...", and that statement of yours makes no sense anyway. If he chooses a shutter speed and f-stop that he deems necessary, he HAS to use an ISO that will give him the right exposure with those other settings. The three settings work together to get the right exposure. If you change one (or two) you have to change another one (or two), but you still end up with the same exposure.

And your statement "....and finds that the highest ISO that doesn't clip away desired highlights is best, which is easily demonstrated to be true both with test shots, and with theory." is way off too. The highlights in the tennis pictures are blown, and even more so after lifting the shadows in post processing.

It's obvious to me that the OP has very little, if any idea of how exposure is linked to ISO/shutter speed/f-stop. It's pretty clear that in the past he was choosing a certain shutter speed and f-stop, and then setting the ISO to a low setting, ignoring the camera light meter, and underexposing his shots (see the very first quote above). Like he also said, he doesn't like to use exposure compensation, so he instead turned up the ISO, which in a way IS exposure compensation when the f-stop and shutter speed are considered to be unchangeable, or "necessary".

What he obviously doesn't understand is that changing any of those things would affect the exposure, and that changing the ISO to a high setting actually decreases the DR and causes more noise/less detail. The only reason he sees more light and detail in the shadows now is because he's closer to the right exposure and he's exposing more in favor of the shadows. He would also see more light and detail in the shadows if he shot at a low ISO and set the f-stop and/or shutter speed accordingly.

How's that for "mental flexibility"? LOL

hi bronxbombers,

first let me stress out... i just want to share my findings (i'm in no way the athority to this ISO settings)... most pro photogs will recomend low ISO on a sunny day shoot...

LOW ISO sample

this is a good good example of what i want to avoid, this is the fresh from the card image @ ISO 100:



this is the enhanced/edited version... i created three (3) layers to create this finish product...



HIGH ISO sample

now let's check the actual image when i begun to switch to HIGH ISO

these are straight from the card jpg images... you'll see the faces are more detailed (i'm not talking about super sharp) here... now it's easier for me to edit and enhance without any layers...





really, i want high ISO (under sunny day shoots) not for stopping the action... but for easier and faster processing of images...

and i just want to share that... using HIGH ISO under sunny day shoots will really NOT lose details...

thanks for sharing your excellent images!!! love them and very detailed and sharp!!

can post the actual full view (fit to screen)?? thanks!

=D

and maybe extending flash range. For available light shooting without fill, in terms of dynamic range and detail within DOF, you are better off at low ISO settings. NM just prefers using high ISO in these situations. I suppose it sees it as a unique positioning strategy relative to other photographers, but in terms of results, there's not much in it.
sunny day, between 10 am - 2 pm... outdoor shoot...

low ISO 50 to 200 or high ISO 640 - 1000

hi photo genie,

thanks for the kind words!

=D

i used to use light meters (indoors)... but i think because of my daily work as a PJ... i've become so used to using the camera's Evaluative Metering and i manipulate other setting as i wish...

and now... even indoor shoots... i've become so used to NOT using a light meter... and so far i like my results... EVEN if i use flash strobes (not the speedlites/580ex)...

=)

and that's one reason that i want to get out of the box and use high ISO on a sunny day shoots...

again thanks!
And again, your raw/untouched examples are far better than the other
pro photographers I've worked with and I've seen! Honestly!

And instead of showing some ratios and charts after charts of
exposure settings and its equivalents, you are showing actual images,
which I really appreciate.

Very well done and congrats!

Do you use a meter reader during your shoots?

Thanks!

xoxo
does anyone see an improvement in the shadows there? Look on the
trees...
They look pretty closed up to me....Of course the model is well lit
up due to the flash fill in...

Love the shot tho! :)
hi aB... thanks for pointing that out... =)

the image above was the processed/enhanced version...

here's the UN-TOUCHED jpg file... fit to screen... (below is the
enhanced version)...

as we continue this discussion... looks like only me and Sunny Kalsi
(so far) love high ISO outdoors...

thanks a lot... =D

i'm in no way the athority to this ISO settings
Fair enough.
this is a good good example of what i want to avoid,
When shooting baseball caps on a bright sunny day, you should use sufficient fill flash to properly expose the faces. Also, this is just my preference, but when I ask an entire team to pose for a photograph, I generally shoot RAW so that I have the most latitude possible to "save" the image should a region be underexposed, but that's just me, and I understand you want to keep it simple with jpeg. Fair enough.

However, you now have this image with underexposed faces, so let's see if we can push it in a direction "you" like without complicating your workflow.

Here's your (reduced) original.



Here's one "possible" adjustment using the Fill slider in LR (takes about 2 seconds).



Now, I did not blow the highlights like you did in your adjustments, and perhaps you like that blown look, which is fine, it's your preference, and I could easily blow the highlights if you prefer. I left much more detail, for example, in the foreground sand, but that's my preference and not necessarily yours.

But my basic point is, you can recover these underexposed regions in a couple of seconds without creating layers and other complicated steps. In fact, you could adjust an entire days shoot in just a few minutes with an application like LR, and you could even create a template for the NM blown highlights look. In addition, if you had used RAW and ISO 100, you would have had more DR and less noise with which to recover the underexposed regions. Finally, when possible, try to properly expose the subjects during the shoot. That will almost always reduce the effort needed to correct the image during processing.

Best,
Christopher
 
thanks for taking time in processing the image! excellent work!! love it!!!

great difference!!
