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.

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.
