----- Original Message ----- From: "Joseph Chamberlain, >I am very happy to have had the opportunity to access this information and the feeling of "understanding" it gave me over what is happening inside of it. It also made me understand multiple aspects of RAW files and how digital cameras operate. glad to hear it helped :-) >I have also tried to use your first suggestion but have not been able to make it work. In your suggestion you state: > "Open picture in one of exif viewers and find field "Unknown (0093)". It > should look like: > Unknown (0093)3,9: 18,Y,X,0,0,0,65535,65535,0 > Important are Y and X. If Y is 0 then shutter count is X. If Y is 1 or > more, then count real count is Yx65536+X. Y increases for 1 every 65536 > photos" >Do you know of any EXIF viewer that will provide the capability to search for a specific string of data or a specific field ? 'exifer' allows the exif data to be exported to spreadsheets. Since it's not a large amount of data exported, exporting for each folder would not take up a lot of hard drive space, then the spreadsheet could be searched for particular snippets of information. Exifer and other exif viewers can be found here: http://www.earthboundlight.com/phototips/exif-reader-software.html unfortunately, exifer appears to be a windows only program - you may find another listed that supports the same or better functions for the mac on that same page. >The problem I've found with EXIF viewers is that they are prepared to display certain "standard" information - those that are generic for digital cameras and images. The information that is specific to one particular model of camera is not displayed by most EXIF viewers and remains hidden from the user. below is an export of the data displayed by 'exifer': E:\images\a\new a shots\100ND100\DSC_0004.JPG Make: NIKON CORPORATION Model: NIKON D100 Description: Date modified: Wednesday, April 23, 2003 11:59:13 PM X-Resolution: 300/1 Y-Resolution: 300/1 Resolution unit: Inch Firmware version: Ver.2.00 YCbCr-Positioning: 2 Comment: Date taken: Wednesday, April 23, 2003 11:59:13 PM Date digitized: Wednesday, April 23, 2003 11:59:13 PM Exposure time [s]: 1/100 Exposure program: Manual Exposure mode: Manual Exposure bias [EV]: -1.67 F-Number: F7.1 Focal length [mm]: 60 35mm focal length [mm]: 90 Max. aperture: F2.8 Digital zoom: Off Subj. distance range: Unknown Flash: Not fired Metering mode: Spot Gain control: None Light source: Unknown White balance: Auto Contrast: Normal Saturation: Normal Sharpness: Soft Colour space: sRGB Subsec time: 90 Subsec time original: 90 Subsec time digitized: 90 Sound file: Sensing method: One-chip color area sensor File source: DSC CFA pattern: Custom rendered: Custom Scene type: Subject program: Standard Image width: 2240 Image height: 1488 Components configuration: YCbCr Average compression ratio: 4/1 EXIF version: 0220 FlashPix version: 0100 Makernote: 4E 69 6B 6F 6E 00 02 00 00 00 4D 4D 00 2A 00 00 00 08 00 1E 00 01 00 07 00 00 00 04 30 32 30 30 00 02 00 03 00 00 00 02 00 00 00 C8 00 04 00 02 00 00 00 08 00 00 01 76 00 05 00 02 00 00 00 0D 00 00 01 7E 00 06 00 02 00 00 00 07 00 00 01 8E 00 07 00 02 00 00 00 07 00 00 01 96 00 08 00 02 00 00 00 0D ...
