PhotoMill X
Good Application to edit multiple images.
PhotoMill, by Overmacs, is a handy photo utility to use anytime you need to make changes to multiple images. The application is easy to navigate and has a great way to manage multiple images.Description from Website
PhotoMill helps you convert a bulk of images into the most popular image formats, give your files meaningful names, watermark with text and image, adjust photos (brightness/saturation/exposure/grayscale/etc.), fit geometry (scale/crop/trim/etc.), remove private metadata, add your own copyrights etc.
Also, PhotoMill is a great batch metadata editor, image file renamer and photo browser.
Notes on my Evaluation
Seems to be a good solution if you manage a lot of photos. For example, if you have a lot of old pictures that you want to convert to JPG from BMP or TIFF scans.
PhotoMill might be a good tool when creating an online photo gallery. (Quickly create thumbnails)
You can do multiple actions, such as add a Watermark Rectangle and then add a text above the rectangle. It is a cool effect that I haven't seen used in other applications.
You can get a side-by-side preview of the change you're about to apply, so you know what impact your changes will have on the image.
The Info Panel is a good way to get detailed information about images without actually having to open it.
There is a preset for "Prepare for Facebook" with the long edge being 2048 and the method is resized to fix long edges. Originally I thought that 2048 was too big for Facebook, as I thought 1200 was the standard size. However, Facebook own documents recommend using the 2048 width to have the best quality.
The search and sorting features was pretty impressive. I can easily drop a folder full of images and work on ones that meet certain criteria. For example, I can drop a large folder of pictures but only work on the pictures that had the wrong orientation.
This application would be very handy when viewing old DVD data. You can pick and choose which images are worth keeping and convert to today's format.
