Used when fixing dates from cameras where the date was set Works like -ta, but for specifying large date offsets, to be Including 'DateTimeOriginal' (tag 0x9003) and 'DateTimeDigi. This option changes all Date/time fields in the exif header, Or when daylight savings time has changed. Set on the camera, such as after travelling across time zones, Useful when having taken pictures with the wrong time If you happen to have the wrong-set camera still at hand and still wrong, I find it handy to take a shot of a (time-synced) digital clock - then, take the date shown in the picture as 'newdate' and the date in the metadata as 'olddate' for the parameters below.Īdjust time stored in the Exif header by h:mm backwards or for.

It has a simple adjust by-hours command, but for big changes it also has an old -> new syntax which computes the difference for you (so you don't have to worry about leap years and so on). You have to format the dates correctly, but it's easy to do by following the examples (see the documentation I've included below). If you're not used to command-line programs, this is a pretty non-intimidating one because there's not a lot to it. It's completely free (and open source) and is easily available for Windows, Mac, or Linux. I perform this fix on photos that look upright in picture viewer but not other software, so now it looks correct everywhere.The simple command-line program jhead is great for this. Now check your photo will look the same in picture viewer and irFanView, as well as blogger (or other web services).

If it has been set, it is likely something other than 1 -Change the value to 1 -Click “commit changes” Note that it may not be there unless the photo has set a value for orientation. These instructions do not quite match up to the new software package, but it's mostly the same: -Open EXIFeditor and open the jpeg in question -On the dropdown, scroll down to “Orientation”. Update: the old software disappeared, here's a new option: I found “EXIFeditor” and was able to get it to work. There are several EXIF editors out there, but not all of them are compatible with all systems (or even have write capability without paying). The picture can be saved, and quite easily. I wouldn't recommend rotating the photos in the Microsoft picture viewer, but just in case you have already done so (or have a picture that received similar treatment), don't worry.
