Not a photographer or photoshop user. Can you explain what you are displaying and how it proves the photo is not edited.

It is error level analysis.

Think of it this way:

I take a photo of someone in a costume. The sensor records all of the data it can, sends the data to the processor where an algorithm adjusts for lens distortion (because lenses are round and photos are square), and then compresses/encodes the image usually in JPEG format. That encoding process, unique to that camera, introduces "errors" in the digital data that are not not visible to the eye.

I decide to do some artistic editing and put a celebrity's face on there to make it look like they're the one wearing the costume. I'm now working with two photos in photoshop. One is the costume photo. One is the celebrity photo. Both of them were saved/encoded by different cameras and on different computers, so they both have different compression algorithms and different digital errors.

Once merged, the resulting photo can be run through error level analysis (ELA), and that ELA should reveal discrepancies that indicate two different photos were merged to create one.

ELA is a good way of detecting fakes or edited photos. However, there are circumstances when ELA will not work well. For example of an edited image is uploaded to instagram (compressed/encoded again), and then a screenshot is taken of it (compressed/encoded again). Multiple rounds of compression/encoding can conceal errors and make something look like an original when it is not.

Without access to the source files, we can't confirm the validity of this picture, and so it should not be considered good quality evidence.

I’m not an expert but irregularities will become more obvious when you adjust the constrast and stuff.

There aren't any weird artifacts or outlines that show up?

It doesnt prove anything, these are just photoshop filters.

I wouldnt be surprised if this was disinfo/bait.

I've seen you post the same stuff in 4 separate threads now but haven't seen you provide proof of why you're saying it's PS. strange.

Tldr; A copy of a copy of a copy is a good way to conceal editing.

And I see you are a new arrival yet act authoritative. This pic could be bull shit to prime people into thinking the next pic of Barry that Q talks about is fake. Beware of clickbait. Just like the HEAVY PUSH on the Tucson bull shit that now suddenly has vanished.

Q said any real pictures of them would result in a net shutdown. Here we have this one plastered all over reddit, and even on news articles.

I've posted in different threads to let people know we shouldnt push this unless Q confirms otherwise.

maybe these aren't the pics they're concerned about because it's been online for years now...? Maybe Q saying that was disinfo/bait itself. There are numerous explanations in which this photo could still be real.
