Converting JPG pictures to black and white

[Cornish Steve]

I first mentioned this topic a couple of months ago, but now I need to solve the problem.

We have several patent claims pending, and our submission is supported by close to 100 pictures. Many of these are screen shots and in colour. When copied, they are grey-scale. The patent office, however, will accept supporting pictures that are in black and white only.

Someone mentioned that JPG pictures can be converted to black and white using Photoshop Elements. I have this program, but I've only ever used it to convert screen shots into JPG files. Can anyone walk me through the process of using the program to convert my pictures into black and white format?

Many thanks.

Try using irfanview - http://www.irfanview.com/ then open your image from the application, then from the text menu use Image, Decrease colour depth to 2 colours.

That's the easiest way to do it, well that I know of anyway!

Fantastic. This program looks to do exactly what I'm trying to achieve. Thank you!

No problem, let me know how you get on.

Colour to black and white is simple with Adobe Elements. Pretty much one click.

Here is the entire process:

Hiya

FYI:

The process you defined converts the image to grayscale not black and white. Grayscale is typically 256 levels of shade between black and white, the confusion comes from this:

Grayscale is often called black and white when the actual term is monochromatic. And monochrome is a single colour seperated into divisions of intensity (usually 256) between 0% and 100%.

Black and white is 0% white and 100% black, there is no levels or shades in between. The original solution offered seems to be the best.

If elements is at all similar to Photoshop the actual process would be to turn the image into monochrome using the process you defined then convert it to a bitmap image which is a two-colour image (though technically white and black are not colours but absolutes of density So white is 0% density and black is 100% density).

Hope this helps for reference

In photoshop convert the image to grayscale and then from Duotone option select Monotone. Problem solved.

Once again, thanks everyone for your advice. (Yes, I needed black and white because government patent lawyers will not accept grey scale.)

If you have 100 photos to do if you have Adobe Photoshop you can very quickly setup a batch and it will do them all for you without having to do anything apart from a quick setup, if you still need help email me and I will talk you through it.

Batch conversion is also possible in IrfanView under File, Batch Conversion/Rename or open the program and type the letter b to open the batch conversion window.
