OK. thank you for showing how to trun a Color Photo into BW.
But what is the easyeast way around. How would be the best way to create a Color picture out of a BW Photo?
Is there a way to tell GIMP what shade of BW is a certain color?

I also spent many hours in the darkroom trying to produce the exhibition winning, monochrome print and that experience gained is most valuable in the digital manipulation of images. Also, in the production of the exhibition print, there was a considerable amount of hand finishing after the final printing stage. If you have ever tried to remove minor blemishes, such as dust spots or spots caused by faults in the emulsion, by ’spotting’ with a camel hair brush and special liquid dyes, you would appreciate the use of tools such as Clone and Healing. Remember, the generally used film size was 35mm and prints were required to be about 500 mm X 400 mm often produced from only a part of the negative.

Such experience, I would suggest, can be classed as “real BW work” and I have found it very difficult to find fault with Rolf. Indeed, I have been inspired to spend many hours, following and expanding upon his teachings, in my efforts to produce monochrome images from colour images using Gimp, which I would have been proud to have produced in my pre-digital days.

I have made a lot of images in the dark room before – but I don’t think this experience is very valuable for this. Looking at images is a valuable education – and thinking about what you like and why.

I never achieved as good results in the dark room as I do now with the computer. To get a really good image in the dark room you need time, money and experience.

I hope the judging of the conversion was done by someone tempered with years of experience with real BW work in lieu of just digital experience.

Hi Rolf,

Thanks for the tutorials! I found another very interesting way for monochrome conversion, but the tutorial is for Photoshop not GIMP. It is found here: http://intphotos.7.forumer.com/viewtopic.php?t=25&sid=2b7b707f8fd6b5a7bbe56c352adfe702 This way allows to adjust colours individually and you can change the range each colour encompasses. It would be great if this could be done in GIMP!

Thank you for another great podcast. I am a recent fan of yours and over the past 2 weeks I have watched all of your podcasts often while commuting to work. I appreciate the many tips I have gotten from your podcast it has made my adventures with Gimp easier.

I have been in photography as a hobby for about 50 years now and the recent podcasts about black and white remind me of the early days for me as all was black and white due mostly to cost. I’ll be watching for shots I can take to convert to black and white.

Norman, you are right there. I’ll be out and look for my black and white eye….

Stimulating as ever and takes me back to my days in the darkroom. The challenge you have set is problematic in that I believe the sort of images we now go for are based not only on composition but also on colour and may not be suitable for converting to monochrome. Although it is great fun to convert from colour to black and white only certain images would make great photographs. In the old days composition was paramount and colour hardly entered into consideration.

It is so logical, using the decomposition for mixing channels. and yet, I have never thought about that. Something to try for the challenge.

Thanks for the show!

Of course you are right! Just another case of podcasting without thinking.

you made a mistake in the video, when you say that for average of the three layers it must be put 33% 66% and 100%. Thats not that way: the good way is putting the top layer to 33% the middle one to 50% and the one on the bottom to 100%.

In this way, starting at the bottom one, it first have the 100%, when passing through the second one is 50% of each other, and in the third one it is a 33% for the top layer, and the lower ones have 66% to divide in equal parts (50% each) so 33% each one.

You can do a test with the circles you draw, if you try to adjust the opacity when the result is gray is ok (that is with 100-50-33,333)

nice screencast, it discovers me a thing or two about the gimp!
