uncovery

This plugin specializes in displaying all photos of a certain date or between any two points in time. 
It takes away the need to handle each photo individually. The admin can simply 
upload all images in a batch and the system will recognise the date and time the pictures were taken.
The galleries are then displayed by inserting a short code into any wordpress element 
such as posts or pages in the basic format [unc_gallery date=”2006-03-30″].
This plugin is specially made for photo bloggers who often often post several images of a certain event 
such as a hike, a trip, a dive or concert without having to touch every single image individually.
Kaywords added in Adobe Lightroom etc. can be directly used on the website to tag photos and posts.
Additional features include:
<ul>
<li>featured photos: show one or more photos larger than others</li>
<li>dynamic dates: show the latest, first or random dates</li>
<li>date picker: let the user pick the date themselves</li>
<li>seamless re-uploading: any photo can be re-uploaded anytime with a better/different version</li>
<li>EXIF data: The photo description can show automatically generated photo data such as ISO, F-stop etc.</li>
<li>automatic post assignments of tags based on EXIF/IPCT keywords.</li>
<li>automatic post assignments of hierarchical categories based on EXIF/IPCT location info</li>
<li>optional square or rectangular thumbnails</li>
</ul>

This tool will attempt to irreversably change the actual post dates of all entries in the post type you choose (supports posts, pages, and custom post types).
The dates will be changed using (in order of priority):
<ol>
<li>‘exifize_date’ custom meta (date or ‘skip’)**</li>
<li>EXIF date of Featured Image</li>
<li>EXIF date of the first attached image</li>
<li>Do nothing. Be nothing.</li>
</ol>
**You can override the function with a custom meta field named: ‘exifize_date’ which accepts dates: ‘YYYY-MM-DD hh:mm:ss’ (for example: ‘2012-06-23 14:07:00’) or ‘skip’ to prevent the EXIFizer from making any changes.

EXIFize My Dates

It does as advertised. The only thing missing is an option do exify a single post. Whenever I post an older image, I have to check ALL the posts, so that's definitly a point of improvement. That says, what it does it does great!

Great tool to sort posts

Photoblog plugin to bulk change the published dates of a selected post type to the EXIF:capture_date of the Featured or 1st attached image of the post …
