    Smile How to change the background of this photograph?

    Friends at the outset, I must say that I simply love Irfan View!
    I am using v4.10.

    And I just recently discovered Irfan Paint v 0.4.11.64!
    which is a fantastic addition!

    Thanks to all you wizards for both these programs!

    Need some help ...

    Here is a picture of a heroine from India.

    I want to remove EVERYTHING in the background behind her -
    I want to remove ALL the people aimlessly hanging around her
    and have a plain simple white background!



    How can I do that with Irfan Paint?

    I tried doing it but it is a painfully slow process using the brush
    and it is difficult to draw an accurate line around the heroine's bulging curves!

    I have a feeling that there are easier ways to do it. Could you please help?

    Would appreciate any tricks from experts here!

    Thanks in advance and all good wishes!

    I think that IrfanPaint is not the right tool, you should use something more advanced like the GIMP.
    IrfanPaint developer
    The latest stable IrfanPaint version is the 0.4.13.70.
    IrfanPaint is now open-source (released under BSD license).

    I think it will be tricky whatever program you use because you have a very fussy background with colors almost the same as in the foreground.
    I did try the color replacer tool in Irfanpaint on your picture but ended up doing a great deal of manual touching up especially around her hair and that right arm that has another arm behind it. You would probably have the same problems in Gimp or Photopaint trying to create masks with the Magic wand tool and might have to resort to more advanced methods there.

    One tip if you do try painting in the background by hand in Irfanpaint is to use the Erase tool instead of the brush. If you load the background color you want as the IP background color you can paint the background using the left mouse button and repair the subject when you paint too far using the right button. Working from both sides of the boundary like this allows you lots of trial and error to see what works best for you. I get best results using quite a large brush, myself. Avoid using Undo though if you are working this way. Use the right button instead to erase.

    Try also PhotoFiltre and see this german description: "Colorkey mit PhotoFiltre"!

    Well, some workarounds can be done, but in fact IrfanView is not capable of this.
    As said, the background is too fuzzy, with colors too close to those of the object, so the 'fill' function can't work.
    You'll need some paint program with the ability to make a point-to-point selection manually.
    Then wipe the outside region of the selection to be converted to a white background.
    Like this raw example :

    Rest In Peace, Sam!

    I had a try in IrfanView using the 8BF filter GML Matting. It was still hard work.

    Try to get her picture with a nice plain background next time Mepaparazzi.
