Would 510cc be too large? (Photo)

Based on your pictures, I think that 510 cc's would be too big on your frame, especially with a moderate profile type implant.  It will probably wrap around into your armpit!  I don't particularly like video imaging.  I think that you can do lots of things on a computer that you may not be able to replicate in real life.  If you have questions, I think your best bet is to get a second (maybe even a third) opinion with a board-certified plastic surgeon who can examine you in person and discuss your options with you.  That way, you can get differing perspectives.  This is an important decision so spend your time, do your research, and get it right the first time.

The best
cosmetic result in any particular breast augmentation patient depends on a
variety of factors, including: Your individual anatomy, realistic expectations,
a thorough discussion with the plastic surgeon about the options, and an
understanding of the pros and cons of any particular implant choice. Proper
sizing is not just about the number of cc’s. The thickness of your tissue,
breast dimensions which include the width,
height, and projection, as well as chest wall width all need to be considered
when choosing an implant. Trying on implant “sizers” of various shapes and
volumes while wearing a tight t-shirt, bra, or bathing sit at a preoperative
visit will help you and your surgeon choose the optimal implant.

There are no manufacturers' standards for cup sizing in the bra industry. The
cups of a 32 D and a 38 D are significantly different. Cup size varies from
manufacturer to manufacturer and even within styles from any particular
manufacturer. There is also no
direct correlation between an implant size or shape and resultant cup
size.

Keep in mind that following the advice from a surgeon on this or any other
website who proposes to tell you exactly what to do without examining you,
physically feeling the tissue, assessing your desired outcome, taking a full
medical history, and discussing the pros and cons of each operative procedure
would not be in your best interest. I would suggest that your plastic surgeon be
certified by the American Board of Plastic Surgery and ideally a member of the
American Society for Aesthetic Plastic Surgery (ASAPS) that you trust and are
comfortable with. You should discuss your concerns with that surgeon in person.
