How Do I Get Pure White Background?

[jYeary]

Hi guys,

(Shooting on Canon M50 Mark II)

I have two lights, and a white backdrop for my product photos and I can't help but to get these photos with a slight grey or yellowish background.

I really need to get a pure white background so I don't have to edit every single photo in photoshop.(I have lots of products to shoot)

I keep my iso at Auto, and have played around with my shutter speed and aperature.

Generally shooting at f 7.1 and shutter speed from 1/8 - 1/15.

I have tried using the auto white balance, custom white balance by using a white piece of paper, and I've tried using kelvin white balance, but still cannot get that true pure white color.

This is the correct answer!  And, it is the only final solution.  Even if you can get true white, the photo will still need adjusting in Photoshop or some other good editor. May as well start there!

Based on that, would you recommend shooting in RAW or JPG?

Never, never, never, never, shoot jpg.  Always Raw.  The adjustment latitude in Raw is far better than jpg by a huge amount.

One should be careful whenever giving "always" or "never" advice.   True, capturing in RAW will give you far more control and that is my recommended format to use whenever post-work is involved (or may be involved in the future).

Personally, I shoot RAW+JPEG for the following reasons:

* Nice "backup".  RAW gets corrupted? JPEG is there.

* JPEGs can be easily shared immediately without having to first process all the RAW images.

* Reviewing images during a Photoshoot that isn't tethered? I would sync the JPEGs to my iPad which was far faster than syncing the RAW files.

"Never, never, never, never, shoot jpg.  Always Raw."

However our discussion is white BG.  However, I never ever use jpg anymore for any circumstance but that's just me.  It is so seamless now jpg make little to no sense. If I am in a high priority or mandatory situation I save Raw to both CF cards.
