Recommended workflow for professional photographers?

    Being a professional photographer for nearly 20 years I wish to display my JPEG images in the highest quality with file sizes as small as possible.
    I installed WP Retina 2x: https://wordpress.org/plugins/wp-retina-2x/ for I choose to have HD images available for site visitors with an Retina device. In result my uploaded images are respectively 1920 x 1280 px (standard) and 3840 x 2560 px (Retina Ready @2x) which I manually downsize from the Full size originals (5000+ px)

    Question #1: I wonder if it’s better to use Photoshop’s compression method ‘Save for Web’ first before having EWWW Image Optimizer doing the job? I mean: setting the parameters in Photoshop manually and judging the image quality by the eye is preferable, isn’t it?

    On the other hand EWWW might be built to perform better without any preparations by third parties software in advance. Please advise !

    Question #2: With ‘ExifTool’ (by Phil Harvey) http://www.sno.phy.queensu.ca/~phil/exiftool/ I can remove EXIF Data partially from JPEG files to keep the file sizes to a minimum. Of course I like to keep important EXIF Data – like copyright and contact info – in my images, but want to get rid of all other junk. Is EWWW Image Optimize leaving the EXIF Data I left to stay intact or is it cleaning it all?

    Looking forward to your comment !

    answered via email, posting here for posterity:

    1. From my experience, the lossy compression performed by JPEGmini is far superior to what Photoshop does. The quality level set by photoshop is a hard limit, whereas JPEGmini examines the image to determine areas where quality can be sacrificed to achieve better compression. The EWWW Cloud service is going to be switching to TinyJPG soon which is even better. I would suggest that you upload a few of your images to the web interface at jpegmini.com so you can see for yourself, and then compare the results with what you can achieve with Photoshop. All that said, I’m not a professional photographer, I’m a programmer, so I would be most interested to see what you think if you do try that experiment.

    2. Both. The Remove metadata option lets you choose whether you want to strip the metadata (which includes EXIF information) or not. In your case, you can just leave it turned off, and keep doing your manual cleanup of EXIF data, and you should be just fine. I saw a plugin a while back that pulled the copyright info into the WP database, not sure if there is anything for other exif data or not. That would allow you to preserve the exif data (although separately from the image itself) and make the files even smaller if you wanted to.
