Lost: ISO settings

[johnd]

When looking back thru some shots that didn't turn out too well, I was wondering what ISO setting I used. But I couldn't find ISO in the Exif data in PS? Or am I looking in the wrong place? Surely it's recorded with the shot? Any help finding my lost ISO settings will be much appreciated.

Cheers

John, some save options in PS and other programs strip out the EXIF data. Do you have the original file (as shot from the camera) or some other derivative (e.g. NEF -> TIFF)? If you open the original you'll be able to view the EXIF.

search the forums for "isofix"

itsa ulility that adds a right click menu to directories and "fixes" all nikon images to rename the "sensitivity" tag back to "ISO" which is recognised by various applications.

Nikon decided to use a unique exif field name, which gets ommitted by many programs and website applications.

How do you get the images from your flashcard to the computer? If you use Nikon Transfer and click the little tool box icon top-left it will include the ISO. Where are you looking in Photoshop?....the metadata tab bottom left should show it.

[johnd]

Matt, I'm looking in the metadata tab Camera Data (Exif). I can see all the other data you'd expect there, but not Iso.

Darb, that sure sounds like the issue. Before I go downloading the isofix and applying it to my folders, does anyone know if the new D70 firmware fixes this "bug"?

nah it doesnt.

Interesting problem, that I have never had. PS7, PSE3, PSCS and PSCS2 all displayed ISO correctly. I use NV to copy NEF files to my computer.

Ah... and I thought it was just me... I've never had any trouble seeing the ISO setting in PS or IExif either...

I sometimes use Nikon Transfer to copy my files across, but also use Explorer sometimes...

What exactly are the symptoms that people are experiencing???

[darb]

i dont believe the problem exists with NEF's

but i see it occur if i shoot jpeg ... then pull jpegs directly into photoshop CS, make changes and save to the jpeg. CS omits the "sensitivity" field when saving as it doesnt read that field. It only knows to look for "ISO"

From a website perspective, most web softwares like gallery, coppermine etc look at the "ISO" tag in exif when displaying exif info, so even if the "sensitivity" tag IS kept intact during post processing (lackthereof) .. most websites will ignore the tag. (though if you downloaded the master image and ran your own EXIF reader over it to see "all" exif tags, you would indeed see "sensitivity" )

two examples, both shot jpeg (dont ask.)

This one had the "isofix" tool run on it : http://darb.net/select-photos/DSC_6908

this one didnt : http://darb.net/select-photos/DSC_5888

(you notice under each image the website software dumps important exif tags, but the cityscape one has no "ISO" because i forgot to run the tool.)

John, I've got the ISO fix program (version 1.2) on my site here:

How do you transfer your images to the computer?

[johnd]

Matt, I take the card out of my d70, plug the card into a usb card reader, then use windows XP my computer to copy from the card into a folder on my PC. Then I manipulate the files with PS. All jpeg, I haven't shot raw yet.

Maybe I should be using some other process to get the images onto my PC?

Cheers

[darb]

that the way i do it

infact, i just plug the d70 in, and it appears as a drive, copy files off that way. I use it in mass storage USB mode.

Refuse to touch any nikon software.


First thing i do after copying the "darb1" directory (or 100NCD70 default) is to right click the new directory and choose "isofix" ... it zips through all my images and renames the exif tag so that photoshop is aware of it, aswell as web apps, gallery, and other simplified exif readers.

When you transfer the files that way...do you also drag the little file marked "NIKON" or something, along also? I suspect...but not positive...it is essential for the EXIF...or some of it.


I could get shot to pieces here.

Thanks to everyone for their suggestions. All is now isofixed.

Following on from darb's suggestion about isofix, I downloaded isofix12.zip from Onyx's website (thanks Onyx), installed .net framework 1.1, installed the isofix and then right clicked on all my folders containing original pics, selected isofix and as if by magic, the iso settings were there. Great bit of software.

Unfortunately, anything that I had processed with PS couldn't be fixed by isofix. Oh well, you can't have everything.

Thanks again all,
cheers
John

good work mate.

i regularly forget to run isofix, but i dont always care. Its obvious its iso200 when its a landscapey type shot ... but if its sports or action, its nice for people to know what ISO i went to (read : how much quality i would sacrifice to shoot safely!)
