Delete exif info in case you need
 

Ok guys

This is the secret...

1) make the shot
2) make a jpg image from lightroom
3) make a new empty file of the same size in photoshop
4) copy and paste your image in the new file and save....

ALL THE EXIF INFO WILL BE GONE

Can you explain why this might be needed?

Let say that personally I think the exif info are really usefull.... but sometimes you may have the need, who know.
People is strange! :-)

...or alternatively, just 'save for web' in Photoshop.

I may have said it beore here but EXIF is odd. Quite a number of people hold it in awe or at least impart some mythical status to it and believe that it holds the secret to all photographic mysteries.

Personally I don't see the point as it tells you precious little about a shot that you couldn't glean from an evening of reading a book. If a shot looks blurry it was taken hand held with too long a exposure, it its out of focus with too wide an aperture. Action shots are taken with a fast shutter speed, flowing water with a slow one what more is there to say?

Some think that possession of a jpeg with EXIF has some proof of ownership in law. It does not, anyone can add their own EXIF to a jpeg.

OTOH you can put contact and attribution details into the EXIF data. Deliberate removal of which is an offense in the US under the DMCA. All my shots have contact and attribution data.

ADDENDUM: Some cameras stick GPS data and other personal information into EXIF. Some people can well do without that.

Good points.... actually to me exif are usefull to myself in order to learn from my own mistakes... i never check exif of others photos. I check the final result not exif.

Personally I manage quite well without it, and to be honest I don't see a use for it other than to give other people my info. The way I see it is if you need details of a shot you took then you're not familiar with your own equipment or your own photographic technique. If it's a snap shot, then does it matter anyway ?

nirofo.

Exactly.... it helps me to understand my own equipment better!

I think it emanates from the photo mags and books. They always put (f5.6 1/125) next to all the photos they printed. As if it mattered one way or another. I wondered for a bit if I was missing something important in these numbers, but soon realized it was just what we would nowadays call a thing with geeks and numbers.

Its perpetuated in the photo cataloging programs which make a great play on being able to index on shutter speed or f-stop. I really want to collect together all the photos I ever took at F11 - NOT. You can get programs that will go through your hard disk and report back on your average shutter speed (yawn zzzzz). What you can't get is program that will show you all the Dragonfly photos you took in Northamptonshire. Well they will but the method they use to allow you to tag them in multiple ways is awful.

This is an awkward and bad method. JPEG is a lossy format. Each time one resaves JPEG photo, more of the image quality is lost. To do it right and fast, you better off using specialized software, like this freeware to remove exif data.

This is under active research. Hopefully such technology will get mature and available soon.

Hopefully. The best I've found for my purposes so far, is windows live, except that it keeps the database in "applications data" and when I looked it was up around 4gb which I thought was a bit naughty to have on the system drive. So currently its disabled until I stick a TB drive in there.

if you save jpg max quality loss is quite invisible ... depend on what you need photos for.

It's a good idea to delete exif info in case you're publishing photos on Flickr/social nets/etc. You may want to hide GPS coordinates taken from a built-in receiver, or date&time, or equipment-related information. And I personally use this batch exif remover for that purpose. The good that it lets me to selectively deal not only with exif, but also with Adobe XMP, IPTC, and other photographic metadata.

Besides GPS info, I can't think of any reason to withhold EXIF info... IMO. Unless you consider your work to be of such worth that someone might "steal" your "technique". Other than that, it's all a bit tin-foil-hat as far as I'm concerned.
