PhotoME or How to view EVERYTHING in your EXIF data

Hello,


It seems like the Wine-Team has changed something between version 0.9.33 and 1.1.15, so that some function doesn't work identical to the Windows versions of the functions anymore.
I'll try to figure out where the problem comes from and report it to the Wine developers.

You could try to use the GDIplus-library which is available on the PhotoME download page.

PhotoME problem...

Hello,



There are no known problems with the latest release. I assume there was a problem with the update-server while you've downloaded the update, so one of the databases are defect.



Please open the folder:
C:\Program files\PhotoME\data\

Can you please compress the content of this folder and the content of the sub-folder (makernotes) using ZIP or RAR and send it to photome@inbox.com?

After you've done that, please delete the file update.xml, which is located in the data-directory.
Now run the Update-function of PhotoME (in PhotoME: Settings-menu -> Online-update...).
After the Update-process is finished everything should work again.

Cu, Jens

Hello,


You need to click on the image to show it on Flickr.
Then click on the small magnifier icon, and after that on the "original size" link.

The original size image contains the metadata.
I assume Flickr remove them while generating the smaller size versions of the image.

Hello,


Thanks for this hint!

A new Pentax database is available on the PhotoME update server (in PhotoME: Settings-menu -> Online-update...). After you've done the update PhotoME will show "DA or DA*".

K10D update and Model Revision 8.1 Yes /No??

Hello,

in the next version of PhotoME, I'll change the "Model revision" tag.

I think I'll split it into "Camera was serviced?" (the first number) and "Production ID?" (the second number), or has anyone a better idea?

It seems like both numbers are not related to each other.

Old Timer 56 has written that his number changed from 1.5 to 8.5, flyer has written his number changed from 1.2 to 8.2 and Frogroast has written his number changed from 1.1 to 8.1.
If it would be really a major/minor version number, the minor version should be changed too - and not only the major version.

Now there is just the question where the differences are between the 5, 2 and 1 in the second number, and between 1 and 2 in the first number.
Has anyone an idea?

To figure out if something changed while the camera was in service, I think the DSPFirmwareVersion and CPUFirmwareVersion tags are more useful.

Hello,

maybe I can clean up the things about the "Model Revision" a little bit.

First, about me: I'm the author of PhotoME.

Since Pentax does not provide any informations about the maker notes, the complete maker notes decoding base on reverse engineering - not only by me and the PhotoME users, but also by Phil Harvey (author of ExifTool) and the users of his software.

Many things can be figured out by taking some shots using the camera and compare them. For example the Hometown city tag (0x0023) was easy to decode by shooting different images with different settings and then compare the data the camera write to the metadata.

Other data can't be set or seen on the camera, like the "CameraInfo" tag, which contains 5 LONG (unsigned 32-bit) values:
"Pentax Model", "Manufacture Date?", "Model Revision?" and "Internal Serial Number?".
Here you can only guess their meaning.

By comparing shots of different cameras it's easy to see that the first value is the same for the same model and different for different models. That means this must be a model-identifier (the "Pentax Model").

The second value looks always like a date. Since it indicate a date before the user bought the camera, it must have something to do with the manufacturing of the camera. But that doesn't mean it's the date where the camera was assembled - it could be also the date were the EEPROM was last written, or something like that. That's why PhotoME show a question mark behind the tag title.
The only thing which is definitely, is that this date is important enough for Pentax, that they decided to write it into the metadata. ;)

The third and the fourth values are combined by PhotoME to one value, because both numbers are always very low, so it looks like a version number and sometimes it increase after the camera was serviced. That these 2 numbers are a "Model revision" is just a guess (indicated by the question mark).
Maybe these 2 numbers don't need to be combined. Maybe they are no version number and have a totally different meaning.
Like some users in this thread figured out, the first number change to 8 after the camera was serviced. That's an very interesting observation. I wonder if it change again if the camera was a second time in the service.
Maybe the second number isn't a sub-version - it could be really everything, a ID of the factory which manufactured the camera, a ID of the assembly line in the factory, or an ID for the market for which it was built (Europe, America, Asia...).
It could really mean anything - and I'm very thankful for every hint or idea. ;)

The same count for the last value, which is shown as "Internal Serial Number?" by PhotoME. It seems to be unique for a model and seems to increase for different cameras of the same model - just like a serial number. I've already heared from people that this serial number changed while the camera was serviced. That means Pentax either replaced the complete camera (which is unlikely), or at least the part where the this number come from.


Only Pentax can tell what these numbers really mean - but they don't seems to be very interested.
I wish they would enlighten these things a little bit, but I assume this will never come true. :hmm:

Hello,


Ok, thanks for the info[/QUOTE]

PhotoME show only the informations which the camera write to the metadata.
If PhotoME show 1/90 sec, the camera has written that to the metadata. Since it's very unlikely that the camera write a wrong shutter speed to the metadata, it means the camera actually used 1/90 sec and not 1/125 sec.

PhotoME or How to view EVERYTHING in your EXIF data

Hello!


I don't like programs with hundreds of menu items and sub menu items, and sub menu items of the sub menu items, so that you need to search what you are looking for. ;)

The "design" of PhotoME is very common in Windows. It's used in the Control Panel, in the Search dialog, in many places in the Windows Explorer, Help menu and so on.

But if PhotoME get more features, maybe some day I need to do a menu too.


Thanks for making PhotoME public. :lol:


That's already on my to-do-list for one of the later versions.


I'll think about that for one of the next releases. :)
If everything works well, the next version will have an integrated file browser mode with preview images, so switching between the images will be easily possible.


That's a great idea! I'll put this on my to-do-list with high-priority.

Thanks for your feedback!

Hello!


Please check this page: Opera Menu Extension. :-)
(Make sure to read the "important note")


I'm always interested in the opinions of users - only with feedback I can improve the program.
Is it really important to have an Windows menu bar?
I thought to have the menu on the left is easier to use, because you can open and save images with just one click instead of 2 clicks in a Windows menu bar ("File > File open")



Like mattdm wrote, sensor noise increase with the temperature. That's why it could be interesting for Pentax to monitor the sensor temperature.
Additionally there is a extra block with battery informations. If it would be the temperature of the battery, this information would be most likely located in this block.



It's hard for me to decide which data are useful for the user, and which data are useless.
For one, the informations about the battery could be useful, for others it could be useless - that's why I show all informations and let the user decide which informations he want to see.

Additionally to this, there are tag-suppression functions in the options menu, which allow the user to hide groups of tags, which he don't want to see - this feature will be improved in future versions, using the feedback I get from the users. A search/filter function will be also implimented in one of the next versions to find tags easily.

Cu, Jens
