I Want Sharp Image (New Camera or Macro Lens)

[margzxero]

I have canon 750D, I want a nice sharp/clear image of my jewelry, do I need to invest in macro or buy new camera.

Thanks

If you do, the reason it isn't perfect white is because your camera tries to make everything a shade of grey.  In this case it is trying to get to a 18% grey shade.  It doesn't quite make it but it still tries.  18% grey is where the exposures are made as a default.  Sometime it makes getting a true black or in this case perfect white difficult.  You need to adjust it in post editing or some sort of exposure compensation.  Remember all great shots are made in post, not in the camera.

Thanks for the help I will get back to you, once I have the macro lens.

I think it's time for a reality check. Since you're evidently doing this photography as part of your day job, and since the results you're getting are not acceptable for inclusion in a professionally produced brochure, you'd better step back and admit that you're underequipped and over your head before you dig the hole any deeper. My suggestion would be that you ask your boss to let you engage a professional photographer. If this is just a one-time thing, let him/her finish the job and be done with it. If the requirement is that you learn how to do it right, make sure the professional is one who can and will help you assess your equipment needs and get you on the right track. If possible, sign up for a photography course at your local trade school or community college. The advice you're getting in this forum is from people who are mostly skilled and knowledgeable, but who don't understand your situation very well. If your reputation is at stake, you probably need better than that.

My previous company is satisfied with my work on clothes and some accessories without diamond.

You would do well to heed Robert's post. It is clear to me that you are in denial.

with the current setup I have, that is the best I can do.

"... that is the best I can do."

Is it?  What post editor do you have or use?  We can tweak what you have and make it better with what gear you have.  Look how much better it is already.  What editor?

[margzxero]

That is still RAW file, I know how to use photoshop and adobe lightroom, I did not edit it yet because my boss told me he needs more sharp images.

No...you can try backlighting the diamonds with one of your flashes.  The brilliance in the diamond is all in the lighting.  Go to a jewelry store and you'll see how they light them up.  It is easier to do it with fixed lighting though so you can see it without having to take the shot.  Get a bunch of daylight bulbs.

"That is still RAW file..."

Can't be as you can not view a RAW file. It has to be converted into something else.  Like a tif or jpg.

"I know how to use photoshop and adobe lightroom..."

Outstanding, this is where you need to get more u close and personal.  It is the missing link that will make the shots great.

" I did not edit it yet because my boss told me he needs more sharp images."

You should have.  All lenses need 'lens correction' applied.  The best way is with post editing.  The sharpness can be enhanced in post, too.  Post is where it happens and all comes together.  If you are unwilling or unable to use or do the required post editing,  the shots will never look as good as they can. Even if you buy the best macro lens Canon makes.
