Please post here all your suggestions and comments regarding EXIF data hadling.

Hi,

i just installed the latest beta ... Very Happy ... good work! But i have these suggestions:

The "date", which can be inserted in the "text1" and "text2" fields, should be extended by the item "EXIF date".

I really like having the date under the image title - but this is the file date. In the actual case, every pic has "8.8.2008", because this is the date i copied all content to the path with the V2 version. Anyone, who wants to know the "real" date, has to go to the EXIF info.

So, extracting the date from EXIF and adding this as an alternative option for the image information "text1" and "text2" would be great. In addition, the sorting "da" and "dd" should be extended by "eda" and "edd", so you can sort the pix by the real date.

If extracting the EXIF data by each call of an album will slow down the album or the server, the date information can be extracted while building the thumbnails and they can be stored in the thumbnail file or anywhere else in the content folder.

I integrate the last version and exif items are displayed. So we can say it works

I'd just like to talk about display format for Exif items. Actually if you click here and look for by roll over mouse on image info button, you can see how items are displayed ( and Bruce Willis without make-up also ).

ACDSee program show me Exif parameters of this photo and i suggest you change format like this :

FileName : do not change
FileDateTime : "13/04/2008 19:46:20" instead of "1219267210"
FIleSize : "121 Ko" instead of "121558"
Make : Can you change item name "Make" by "Brand"
Model : Just display item name "model" and not change value format
DateTime: do not change
DateTimeOriginal : do not change
DateTimeDigitized : do not change
ShutterSpeedValue : "1/8 s" instead of "3/1"
Exposure Time : "1/8 s" instead of "1/8"
Fnumber : "F/2.8" instead of "28/10"
ISOSpeedRatings : do not change
ApertureValue : "F/2.8" instead of "2970854/1000000"
ExposureBiasValue : "0.00 ev" instead of "0/3"
FocalLength : "43 mm" instead of "43/1"
Flash : "Flash not engaged" instead of "16"
ExifImageWidth : do not change
ExifImageLength : do not change

You can find specifications of exif here :
http://www.exif.org/Exif2-1.PDF

You should have a look about pages :
- 21 for tags structure
- 34 and 35 for attributes structure

I know it's not in the standard EXIF tags, but adobe embeds the name of the lens used when taking the picture.
would it be possible to show this information in the exif list?
thx

xml example from photoshop

<rdf:Description rdf:about="" xmlns:aux="http://ns.adobe.com/exif/1.0/aux/">
<aux:SerialNumber>530118351</aux:SerialNumber>
<aux:LensInfo>24/1 105/1 0/0 0/0</aux:LensInfo>
<aux:Lens>EF24-105mm f/4L IS USM</aux:Lens>
<aux:ImageNumber>96</aux:ImageNumber>
<aux:FlashCompensation>0/1</aux:FlashCompensation>
<aux:OwnerName>unknown</aux:OwnerName>
<aux:Firmware>1.0.4</aux:Firmware>
</rdf:Description>

I second what Safe has posted here. Also, I would like to request the ability to change order of the EXIF variables and also their descriptions. I have tried arranging the order in imagevue/include/ivExifParser.class.php but it does not affect how they are displayed within V2. Overall I love what you guys have done with the EXIF function...great work!

Well... atleast something been granted, now you can sort exif fields order.
You have to edit imagevue/include/ivExifParser.php there is a list of exif fields, just sort it in the order you want.

PS. I mean after we release update.

Ok it seems we need to do some formatting/conversion with EXIF output ... I already have a few suggestions, but if anyone wants to add any further instructions, please do!

One thing that everybody should be aware of is that manufacturers can change the meaning of the data. For example Flash 0 always no flash but 1 which is Flash in the generic Exif data is different for Canon they use it to signal that the flash was set to auto.

Hello,

I already posted this suggestion on another place of the forum but I see this is a specific place for "Exif" suggestion. So:


Capabilities to use the keywords on the Exif Metadata to generate folders, like Taxonomy on Flickr (or spotlight on Mac, even if these are only virtual folders, so, impossible to use with a server). For example, it could be very nice when you create a folder with a keywords, that every pictures with the same keywords automatically are listed in the folder. You could have a unique item of the picture on the server and it could be possible to display it on several folders with this way. Every folder that contains, "calls" the keyword. Other use of the same idea is when you add a picture, you only have to specific the keyword on Exif and the picture is automatically listed in all the corresponding folders. When you host the pictures and imagevue gallery on the same computer, you just have to specify the keywords and the galery is updated and stored. Very nice !

Keep in mind this feature gives its full power with boolean features ("And", "Or" and "Not"). Typically you can set keywords like this:

"Keyword 1 or keyword 2 and not keyword 3"

With this, you can realy manage folders and pictures like you want.

Well, hope you could do that.
Best regards.

John.

We added EXIF formatting with today's release 20081015. See an example here:

Hello
Additionally to the ImageDescription (description for the image) I would like to have DocumentName (title for the image) available in the ivExifParser.class.php

something like this:
Since I have copied the IPTC value [ip-object] to the EXIF value [doc-name] this would really be icing on the cake of V2

Thanks
wonga

BTW: is it possible to show the "Folder description" on the thumbnail and/or the image page somewhere at a fixed position?

EXIF is awesome! My Sony digital camera stores a lot of valuable information with every picture that i didn't know about...

thank you guys!

Yep, EXIF management is really cool now, specially the way datas are displayed (such as exposure, aperture, etc.) : good job !
And I've just discovered the way they're displayed can be tuned in the .css style sheet

Yey, now exposure time is shown like this:

Exposure 1/60 (0.017 sec)

instead of

Exposure 5/300
