Change Photo colorspace in Bridge

Hello,

I have hundreds of photos which I need to change from (most of them) RBG to Grayscale and I want this change permanent and replace the original photos.  Also, they are all placed in individual folders...  so let's say 600 photos scattered among 100 folders.  I would like to open them all, change to greyscale and replace the originals. 

Is this possible?

    Although you can go to Photoshop via Bridge, write an RGB-to-Grayscale Action and insert it into Bridge > Tools > Photoshop > Image Processor, the command cannot be applied automatically to a group of folders (you mentioned 100), nor does it delete the original file.

    A custom Script may allow you to do more than Image Processor, but I assume you do not know how to write Script, nor is it worth the effort for only 600 images. I suggest using Image Processor, and handling the Folders individually, followed by deletion the original RGB images.

    I believe it would be prudent to never delete images until you can confirm that subsequent editing has not destroyed the original.

    This cannot be done in Bridge. You would need to create an Action in Photoshop that converts the photos to grayscale. This is NOT colorspace, which would be sRGB or whatever. You cal use an adjustment layer, channel mixer, desaturate, or a few other methods to do so. Camera RAW can do these conversions but it can't be scripted.

    I would seriously suggest that you manage this properly with a backup first. It is any easy matter to create new grayscale versions from the colour, but not easy to create colour versions from the grayscale. There are many ways to convert colour to gray tones and a “one size fits all” approach is generally not a good approach for best results – which is why Photoshop offers the “Black & White” adjustment and also why there are many different manual methods favoured by different users.
