I tried to search for an evolution pic of her boobs but couldn't find any. I mean pre boobjob, post boobjob, after her first rework
Why? Enjoy Carmella Bing the way she is.
Just too many questions raised that no one can give an answer to. For example,
You can look at her boobpedia entry:
"Carmella is known for her large tits and round figure. She obtained breast implants in 2006, as her boobs saw an increase in size and looked firmer in her more recent work. Her breast surgery was extremely well done, leaving no obvious scar. In early 2020 she has begun to use the hashtag "naturaltits" in promotional material, implying the size the implants have since been removed. In 2008 she had a breast reduction and her breasts now appear much smaller than ever before now being a mere 36D. Since the reduction her breasts appear to have almost doubled in size due to pregnancy, natural growth, and weight gain, though no new official cup size has been announced. She has shown her ability to perform anal sex with ease in her appearances. She has also been on a good number of adult web sites, including a reality porn style guest appearance as the driver of the famous BangBus."

As stated, she had a breast enhancement surgery in 2006 and a slight reduction in 2008. Her first scenes on any website were with Brazzers. As far as I can tell or remember, she's always had enhanced boobs. As for mainstream videos ...

However, your attempts at finding any of her pictures may be futile. As far as modeling/agency sites there are none. Boobpedia mentions Davia Ardell who introduced her to an unknown agent and that's how Carmella got into the adult business. Would that agent be in Las Vegas? Or Los Angeles? Or Phoenix? Or somewhere else? You may need to consult a plastic surgery website provided, of course, that her doctor (if you can find out his name) posted something and if Carmella agreed to be a subject patient. She would have had to allow him to release her pictures. Most times, a model won't allow that. Also at this point, making it much worse, is that fourteen and twelve years have elapsed since the time of the surgeries.
Your attempts to gain an "evolution" of Carmella's pictures, i.e., "pre boob-job, post boob-job, after her first rework" may just be useless at this point. There are just too many unknowns here.
I wish you the best of luck in your endeavors here.
