Walmart obviously isn't familiar with B&W, so it has coloured them all. Here's the desaturated version of the first one:



I'm glad it wasn't my eyes seeing colours that weren't there Smile

I like the second one. The color tone gives it something extra, in this case.

wow. i had no idea. how do you do that?

since bw400cn is c-41 processing, does the walgreens scanner computer do that? or processor?

Since I've never even seen a Walmart, let alone used one, I really don't know what they did. The image they supplied is in RGB mode, which might be useful to you (I'm not sure), but the colours aren't balanced properly to give grey. The top one almost has a sepia tint.

it is walgreens, which is a super drug store that offers one-hour c-41 processing. walmart does not process any more. anyhow, can the desaturation be done on photoshop or some other accessible program?

Yes, in Photoshop, there are several ways. The simplest is to open the file, go to the image/adjustments menu and select "desaturate" (which is what I did). More complicated is the image/adjustments/channel mixer, where you can tick "monochrome" in the box that pops up and then adjust the intensity (or contrast) of the three different colour channels as desired - that is most useful for converting a proper colour image to B&W.

Like picture #3 ... that snowy effect and bird on tree. Really good. Maybe with longer shot could be...doesn't affect image quality.
