  1. Robert, here goes a Velvia scan. If you look at the negative film scan there is not only more grain, as I can expect from this film, but plenty of white spots (only a few on my sample). The Velvia scan is clean. But I guess Roger was right thinking Velvia is better processed than fast negative processing and maybe chemical are not in best condition.<br>

    On the other side, I am going to give Astia a try, as Scott sugests, as latitude exposure is what I am looking for. <br> Thanks you all.<div>00AFJt-20635884.jpg.b73fd93e4000863836bb3dee181a37ee.jpg</div>

  2. I have seen some extra results with negative film scanned. I usually

    use Velvia or Provia in my 35 mm and medium format, and all tries I

    have done to scan negatives gives me a scan full of dirt and

    scratchs. On the other way, my Velvia and Provia scan are flawless

    (within the possibilities of my simple scanner) I guess if my

    scanner is focusing on the surface of negative film and not on the

    image and so is dirt what is perfectly scanned. Any special clue to

    get good negative scannings? Thanks

  3. Hello

    I have a Rolleiflex with a Tessar f/3,5 coming from my grand father.

    I have been using it from many years ago and I have never been able

    to know the fabrication year. The lens has the Nr 1326578. The

    shutter is a Franke & Heidecke. No light meter.

    Thanks for your help.

     

    Now in spanish -

    Si alguien en castellano me puede ayudar, busco un buen sitio de

    confianza en Madrid para reparar esta camara, quiero limpiarla,

    quizas cambiar el cristal del visor que esta roto en una esquina.

    Algun sitio recomendable aparte de Rollei?

    Gracias

  4. I would like to contribute to this thread saying that I dont see the utility of two ratings criteria. In origin it is true that Aesthetics an Originality criteria could be good ones, but time shows that they goes always related, i.e. they are not independent. I have followed the ratings on some of my photos and I have seen most people rates by couples 1-1, 2-2, 3-3, and so on to 7-7, as some of you have stated before. The meaning of it, as people working with statistics and panel analysis knows very well, is that these two measures are not filling their original purpose as people are using both to say the same. Maybe in origin or with some experts the two concepts are separate and clear enough, but this does not seem the case for most people rating here. What is more, I have seen on one of my photos more than 20.000 viewings, 200 ratings but not one critique. It seems people gets comfortable with rating but they do not like to critique or they do not know how to do it. If this is the case, I woukld rather prefer people not having clear how to critique would not rate, and only could put a note of the like/dont like kind. Great part of photo.net success is how people likes their photos rated, and as highest as possible. However this does not say anything to people wanting to ameliorate, as ratings are so subjective and not well informed as I have said before.

    So, what is what I would like? First, a binary system like/dont like for people not wanting (or not knowing how) to critique, and second, a system rewarding critique much more than rating, to get people involved in critique and discussing concepts and not point scales.<div>00ABUy-20551584.jpg.acf983d4c9bf7938636f19992523d478.jpg</div>

  5. In the case you don't know, you can try those places:

    http://www.usask.ca/lists/alt-photo-process/

    You can find there people like Sandy King,Vaughn Hutchins, Richard Sullivan and others masters of the technique.

    There were other list you could subscribe at

    http://rosebud.opusis.com/mailman/listinfo/carbon

    but it seems is dead.

     

    Look also for the work of Tod Gangler, at Seattle. Colour Carbon, best in the world.

     

    Some years ago I tried this way as I think Carbon is THE technique for colour printing. However it was too difficult and time consuming for me and I gave up. I still regret my decission...

  6. I know this is an old question but from time to time a thread like this shows this is a live question.

    To me, as others have said, the first and only question is being true and honest with your own previsualization. Ansel Adams was effectively a master of tweaking the b&w labo but his images were absoutly coherent with his vision. Talking about the pre-PS era, you can think about Peter Turner, Eliot Porter, and other color masters, or you can think about b&w work of Jerry Uelsmann.

    I ask you to see my landscape gallery. There is some images near untouched in Photoshop but they have been really changed in the taking, say colour reciprocity change, long exposure blurring water, etc. On the other side, some images are very true to the thing but they were so unreal that I was forced to change it on PS and desaturate it(the rocks with the blue colour)

    I think, as I have said before the key is being true to yourself and your image previsualization. If you simply tweak image after image on PS and there is no coherent vision on it, you lose all power you could have got by the technique. So, develop your vision and be faithful to it. Use what you want and do what you need to get the images on your head going out. This is my point.<div>00A24O-20342584.jpg.b7d370001e44e960bf5b80dbe5e7e651.jpg</div>
