Subtle changes, bugs and feedback

Probably a question for another thread... When did phones start auto-putting categories against pictures?

Android thread will tell you when it started on your phone, but the thing which makes it happen is uploading images to cloud storage and having your operating system provider's AI look at them and try to guess what they are pictures of.

If the EXIF is absent

When one uploads an image as an attachement here it gets stripped of its EXIF

How do I check this? Could I add it manually?

Open the file with an image editing program, that should allow you to read the EXIF if present. There are many programs which allow you to edit EXIF

When one uploads an image as an attachement here it gets stripped of its EXIF

Not true.

When one downloads or views an image on this site the image is optimised for delivery and then the EXIF is stripped.

But the upload is intact. During upload we rotate if necessary and then put it in Amazon S3, and on download it runs through Cloudflare Polish and EXIF is removed, and if you are using a .webp compatible browser it's converted to .webp.

We optimise the download, not the upload.

Edit: the screen captures show how lfgss reoriented the 'potrait' pic from main camera app. Vignette pics missing this info then?

Spot on.

Your camera and phone is good, the EXIF correctly allows the site to rotate. The Vignette app not so good, it's removing or corrupting the FlipDirection part of the EXIF.

Thank you for the background info, interesting.

I personally would prefer if the file kept it's EXIF data (thus keeping copyright and IPTC info) though to be honest.

That kinda ruined the Bike Tag game though.

I didn't know you and done that. I have been turning off location in the camera app when taking tag pictures!

Haha, ok, fair enough..

Pretty sure I only store locally... odd.

Ta.

Understood, ta.

Is there a way to pull the exif info? Would make bike tag a lot easier.

Your phone OS spies on you even if you don't use the cloud storage explicitly. You don't need to have full resolution images uploaded to their server, AFAIK the AI which categorises image content works better with less detail so thumbnails will do.

Hmmmm... looks like it needs some development still as all my duckface pouting selfies have been categorised as 'Knob'.

Stripping it completely ruines copyright though.
Is there a way to strip all but this?
I realise this is not a photo forum, but still.. would be very nice.

There are no options to partially keep EXIF. It's all or nothing. A lot is to do with the fact that EXIF whilst being mostly standard isn't actually consistent, different programs create different things and it can be a bit unstructured. It's much the same as Id3 tags on MP3 files, more a convention than a strictly adhered to standard. And on the "optimise for delivery" path, mucking around trying to determine exactly what the program that last modified the EXIF intended isn't anyone's priority... it just gets stripped.

Stripping it completely ruines copyright though

EXIF sometimes tells you who claims copyright. It doesn't have any bearing on who actually owns the copyright.

Could you keep just the IPTC ?

I'm not the one stripping the EXIF, and the options of the program are essentially: "remove all metadata and compress for delivery over the wire" or "do nothing".

I do enjoy a bandwidth bill, and so we will continue to optimise for fewest bytes over the wire.

In my tests on the more extreme end, a 30 MB image can be reduced to 17 MB. But that only happens when all metadata is stripped, and a webp is used instead of a jpeg. When a single image can be reduced by almost half... then we are always going to do this.

The options I have:

• Strip metadata
  
• Strip metadata and compress
  
• Strip metadata and compress and use webp where it is safe to
  
  

There is no option that preserves metadata and yet compresses.

I see!

Thank you for making that clear!

Is there a reason why I can see embedded images in this post via mobile (chrome) but not via laptop (firefox)

I've unticked the box to stop getting email notifications about items I'm watching but am still getting emails. Anyway to stop this but still get notified if I'm replied to directly?

Do you have any extensions/add ons installed on your laptop running Firefox that might prevent the images from showing? Ad blockers, privacy extensions/add ons, that sort of thing. If so, try disabling (these) extensions/add ons and see if that does anything.
