how to have a clear white background of an image

[dherbals]

Any free software available to edit the background of image to make it white?

The best background  for a photograph is a light grey color or something close to the light grey.

My background is a light blue in all of my photographs  ... the gallery photos.

All of my photographs are color corrected using software.  ... and using the light blue background  as a part of the process  to adjust the color ... tint.... of the image.

A bright white background is not good because if one does a color correction using software,  everything in the photo will be a dark color.

I use incandescent light to light up the item being photographed...  Incandescent light adds a reddish tinge to the photo....

and sometimes the color of the item being photographed will influence the color of the photo.

Royal Albert Val D'Or is **bleep**e with a gold trim

Then sometimes things go wrong depending on the "color" of the light being used to take the photograph...  or even the color of the item   where the dinnerware is sitting
