Yeh, black and white ones.I wouldn't go as far as to say B/W doesnt work for me but only a very few bird images would benefit from it IMO.
Hi Bill
Think I am a long way off getting images like Danny Green or Dave Yarrow !
I think your top image above compares favourably though.
Hi Bill
Morning, I do don use it but my landscape-shooting mate who is multi award winning uses Silver Efex Pro (not sure which version).
I think this is regarded as the best conversion package out there.
I have to agree with NSNO.
A good photo is a good photo, whether it's b&w or colour, get it right and b&w can really add to a photo but not every subject works
Any genre of photo can look good in b&w but it's got to be taken with the intention of being b&w in mind, just converting a photo as an after thought won't work in most cases but there's no reason why bird photos can't work well in b&w
Most birds I photography are generally pretty colourful in their own right ,why take away all that colour ...and as BRASH says unless they are black and white birds ,just my opinion on the subject
