I saw a post on Facebook with a photo of Mars taken from the Perseverance rover... wow, they are getting lazy! Look at the photo they posted, horrible Photoshop job and they forgot to add the red filter to the Devon Island photo. the comments are fun, people aren't falling for the BS anymore.
Can you paste the exact image in here? I don't have an FB acct.
Either that or they are actual pictures. A conspiracy theorist will make a thousand rounds of bullshit about anything. Nonetheless, I agree with you about this observation. Forget about the filters and all this other bullshit.
Also, this was my favorite comment to that Facebook post... this is so good.
