I'm looking for some good info on black and white photography using digital equipment. Do any digital cameras shoot B&W? If not, how do I best capture an image before stripping the colour in PhotoShop - I can't see the Zone System being much use... actually, I'm not sure about that. I've used filters to enhance B&W photography with print film but am not convinved a red filter would be the best solution when the CCD is recording colour. I'd be grateful for any suggestions.

The EOS 20D certainly does, and allows 'virtual' filters, too. I just shoot in colour, then use the channel mixer in PS to get the best tones. It's possible to adjust the curves on each channel for the best tonal range before converting to B&W. Cheers, Stu Signature.

All digital cameras shoot in B & W. Its the built in software that creates the Colour Best method is to desaturate (Shift + Ctrl +U ) in any program not just PS rather than change to greyscale. Greyscale reduces the colour count from 16 mil. to just 256 variations of gray Desaturate stays at 16mil >> I'm looking for some good info on black and white photography using >> digital equipment.

Since you mention 16M and 256 I'll assume we're talking about 8 bits channel. In a b&w image the rgb components have the same value. Since we have 8 bits per channel, there can only be 256 different shades of gray. You're probably confused by the fact that when using the desaturate function the image is still in full rgb mode, even though there are only 256 different shades in use. When it comes to converting a color photo to b&w, there is no single best method. How to get the best results depends on the individual photo, and on what effect you want. You may want to have details with some particular color stand out more than others with the same luminance. In this case a simple desaturation will not be sufficient.

I thought you were saying that using the desaturate command, the resulting image would have 16M shades of gray. My apologies if this is not what you meant.

Nope it was the limit of 256 colours that I was trying to avoid as that adds restrictions to further enhancement. >>> I will go along with that I was trying to keep it simple. >> [quoted text clipped - 4 lines] > Nope it was the limit of 256 colours that I was trying to avoid as that > adds restrictions to further enhancement. If your further enhancements are all to be in pure b&w, the only effect of working in full color mode is that everything will be slower, and might even introduce unwanted color. If, on the other hand, you want to apply some effect that specifically adds color, you should obviously use full color mode.

Michael Freeman has some pages on using the Zone System with a digital SLR in his book, called something like Photography with a Digital SLR, can't remember the exact title.

I've got one or two of his books sitting around, quite enjoyed them - though I've got none on digital photography. Searching around, there is one by him called Mastering Black and White Digital Photography - looks a likely candidate. He's also written The Complete Guide to Digital Photography, it could be in that one, but my money is on the first. > Slainte do dheagh shlàinte Justin.

The one I've got was, as Janie suggested, the Digital SLR handbook. It's pretty technical, but has lots of interesting info, quite a bit of which I hadn't picked up before. Once I've got to grips with the info in the one I've got, I'll maybe look at the Mastering B&W one. I'd imagine he's have more about the Zone System there: he really doesn't do it justice in c4 pages. I've really taken to B&W since going digital, though often go on to duotone the images.

My printer is OK for colour (it's not great but it was inexpensive and is by modern standards old) but it is hopeless for black and white so I find toning in Photoshop works best. If I wanted a really good monochrome image I would get it printed commercially although there are some good modern B&W printers on the market. As for filters on the camera, I see no harm in experimenting as the delete function on digital SLR's is a useful friend. Roger Anybody out there know if any of the online services will print monochrome digital images? Thanks in advance. Pat. Roger wrote: > Photoshop works best.

I've had very successful b+w prints from digital from both http://www.photobox.co.uk and http://www.fotoserve.com . Of the two, I'd recommend Fotoserve for quality. Be aware though, that on the rare occasions things go wrong with Fotoserve getting any information from them is a nightmare. It takes about 3 days to get any reply by email in normal circumstances, and they don't provide a telephone number for contact.

Do any digital cameras shoot B&W? Yes, several digital SLR's have a B&W option with filters built in.

Most digital SLR's will autobracket the exposure which you can fine tune and you have the black and white eyedroppers in Photoshop to make the most of your range of tones as well as all the other tools. Treat the exposure more like you would a transparency because burnt out highlights cannot be recovered from the same data. > I've used filters to enhance B&W photography with print film but am not > convinved a red filter would be the best solution when the CCD is [quoted text clipped - 3 lines] > > Justin. |
