I think I was setting you up on that personal control thing! sorry
Using photoshop and a lambda, chromira, lightjet, deveere digital enlarger, one can have all the personal control you speak of. This technology is relatively new ,in Canada I think that our lab is the only digital/traditional lab exposing cibachrome/ fibre paper using a traditional enlarger and as well using photoshop to manipulate files and exposing directly onto these materials. There is no intermediate step that you mention. I believe there are a few shops in NA doing this as well in Europe. I have been waiting 15 years for the technology to advance to a point that I can start experimenting this way. As I stated I have an ink jet machine here and have the great luxuray to do direct comparisons immediately , material to material.
Frankly I do not think one process is better than the other, I have a print of a floral subject that we printed ink jet months ago, the client came back in and ordered a ciba, After viewing the prints I prefer the ink jet as the method matches the feel of the image, even thought the ciba may match the original trans more closely. But my job was to make a believable floral image and the ink jet won hands down.
Another client photographs wet rocks in Labrador , rich in colour and metallic vibe. A ciba in this case blows away the ink jet.
I have no arqument with anyone saying that inkjets are beautiful , but when the discussions starts bashing one product over the other it gets silly.
Cibas are extremely high gloss, some people absolutely hate them, others adore. You should see a scala trans printed on Ciba properly,
Ink jets are generally printed on a beautiful paper stock that is quite alluring to a lot of photographers. Any thing with natural fabrics and earth look amazing on this stock as well as portraits.
People choose their choice of materials and push their qualitys and that is ok , but to start comparing them it gets quite hard to decide which is better.
A simple thing to try is to compare the different black and white papers out there. I did last week and after printing 9 different emulsions , I was suprised to find merit in all 9.
