PIE (picture information extractor)
« on: December 27, 2014, 04:05:03 PM »
I was looking on the internet when I saw this program for free (http://download.cnet.com/Picture-Information-Extractor/3000-12511_4-10257274.html) . I downloaded the program and imported some files to check what exactly can do. I was surprise to find so many information's for example......

-Battery temperature 46C when my a77II showed error with stabilisation in view finder

-Actual Shutter count....

-Which AF point I selected and which one the camera used when the shutter was pressed
......
.......

and the more important from all is the a99 in AF-D mode. It shows all information's about every single AF point (back focus/frond focus) From what I understand the AF module from A99 is very sophisticate and is worth for people that own A99 / A77II to try and see all details about AF status when a picture was taken.

I will evaluate the results and according to them I will do again micro focus adjustment on a99 and a77II :)

Rex, I checked out that program and it does give a tremendous amount of information.

It gives the Image count which is great however the free version does not save metadata changes (which is an excellent feature). it also gives some strange information, as below. My battery temperatures were at 26.1o C.

1) Internal Serial Number: 0707922965.  My camera S/N or lens used is nowhere near that? Perhaps Sony uses that number in some way.
2) IPTC and XMP show nothing if you have not loaded the photo into Photoshop or Lightroom.  I guess that is correct as you have to run the photos through Photoshop to get that info, I think?
3) It shows what you have the Micro Adj set to on the lens used, but the AF Status Active Sensor: (shows) Back Focus (+593). I used spot focus on my a77 with the 100mm Macro and AF micro Adj at 0, so does that mean I should set the Micro Adj to +6. if that is true then that could turn out to be a great feature?  I must start experimenting again. :D

It seems that it is a good program, but at US $39 it does nothing that we cannot do by using exiftool and http://tools.science.si/index.php which gives the shutter count and both are free.

This is my big question also what it means this value. I am on a prosses to find out whatthat means and if is right then the MF adjustment is going to be a plesure to make it

Rex, to check the possibility of using the PIE program to set the AF Micro Adjust, I made a test of my A77/100mm Macro at f2.8 on a tripod with SSS off and 10 sec delay. I took shots with AF micro Adj set at 0, -3, -6, -12 -20 and +3, +6, +12, and +20. I used my 45o test sheet with the lens focused at about 1:2.5 magnification. At 0 Micro Adj, PIE indicated AF Status Active Sensor: Back Focus (+593)

AF micro Adj at -6 was the best (I think) although there was not a big difference from -0 to -12. The -6 gave me about 1/3rd front focus, 2/3rds back focus which is my preference. However I have come to the conclusion that for my camera/lens combination at least, AF Micro Adjust is a storm in a teacup and is not as useful as some would make out. It may be helpful to those with a camera and lens combination that is way out of specifications. The PIE program may be a help there also.

Have you come to any conclusions yet?

Thanks AScot for the feedback information, no I haven't done any further test to come to a conclusion due to some healthy family problems. As soon I find time and have results I will report back.

Thanks again  AScot for the feedback information's

Have either of you come to any further conclusions as to the usefulness of this program? The micro adjust sounds interesting... but having tried in the past without any program guidance - I'm inclined to agree that it's not as useful a feature as expected.

You are correct Charles (Ascot). My understanding of an XMP info file is that it is what is 'attached' to any RAW file that has had alterations done to it in the Adobe Camera Raw edit program PS/Bridge/LR. Any RAW file that is edited will show a small icon on it when you view the images in the containing folder/LR collection - it's small grey circle with some symbol/s on it. RAW files with no editing will not have these icons displayed on them.

If you move any of the RAW files that have been edited and don't move the XMP file with them then you will loose the editing information and, if opened on another computer, you will only see the original RAW data without the edits.

I have done no more investigating of this PIE program and Micro adjust. I am still of the opinion that Micro adjust is not as useful as we all had hoped. I think if you set, for instance, a macro lens to be perfectly micro adjusted at a close up distance, it often will change at a far distance and vice-versa. This applies even more to many other lenses and in the end only creates frustration.

I would agree with you. I felt very frustrated when I tried to adjust a couple of lenses and then had varying focus issues at different focal lengths as you say. In the end I just reset the camera after becoming very disappointed.
