a_petkov Posted April 13, 2006 Share Posted April 13, 2006 Hello, I was scanning a Trix 400 film I got today from the lab. It shows strange pattern/artifacts I have never seen before. Is is something wrong with the emulsion, it looks really strange. <IMG SRC="http://www.purelook.com/nesto.jpg" ALT="artifacts"> Thanks Link to comment Share on other sites More sharing options...
fotograaf1957 Posted April 13, 2006 Share Posted April 13, 2006 Possibly, it was processed at the wrong temperature. Link to comment Share on other sites More sharing options...
a_petkov Posted April 13, 2006 Author Share Posted April 13, 2006 So these are cracks in the emulsion due to the higher temperature? Link to comment Share on other sites More sharing options...
nuno_amado Posted April 13, 2006 Share Posted April 13, 2006 Hi Anastas, It looks like reticulation to me - probably the temperature of the chemicals were not even. If this is the case, you cannot do anything to fix it now but your lab should be held responsible. Cheers, Nuno Link to comment Share on other sites More sharing options...
fotograaf1957 Posted April 13, 2006 Share Posted April 13, 2006 They're not cracks. The size of the gain can be controlled during processing based on the temperature of the chemicals as well as the wash process. Higher temperatures yield larger grain.

a_petkov Posted April 13, 2006 Author Share Posted April 13, 2006 Oh, I guess you are right. Thanks. It looks like I should get those developing tanks as soon as possible and start developing the films myself. Link to comment Share on other sites More sharing options...
fotograaf1957 Posted April 13, 2006 Share Posted April 13, 2006 It's much more satisfying to process your own negatives and you can actually do some pretty amazing things once you get down to a science, the relationship between chemicals, temperature and time.

a_petkov Posted April 13, 2006 Author Share Posted April 13, 2006 Thanks for the replies. Definitely going to develop on my on now ... I do not want to risk any shots in the hands of someone else. The shots on this film a definitely usable for web, but I doubt it will be ok printed out.<div></div> Link to comment Share on other sites More sharing options...
john carter Posted April 13, 2006 Share Posted April 13, 2006 I had the exact same look on some slides one time, and it was definitely for the wrong temperature. I'm sure because it was done by me. Link to comment Share on other sites More sharing options...
geoff_mcauliffe Posted April 13, 2006 Share Posted April 13, 2006 Looks like reticulation to me, too. The cause is often temperature 'shock', large differences in temperature between processing solutions. Normal temp. developer followed by a hot water stop bath could do it. Actually, I think this looks sort of 'artsy', but that probably is not what you wanted from this negative. If you diffuse it in the enlarger it might look interesting?

jmf Posted April 13, 2006 Share Posted April 13, 2006 Classic reticulation caused by temp shock to the soft emulsion. I've also seen a form of this when an acid stop bath was not diluted properly and "pickled" the emulsion. Not to sound too old, but 20 years ago this would have never happened at a decent lab. It's just too easy to do b&w yourself. Link to comment Share on other sites More sharing options...

colin_elliott Posted April 13, 2006 Share Posted April 13, 2006 Anastas, This is definitely Reticulation. Caused by significant temperature differences between the developer and fixer. Your laboratory is responsible! So with negative and print in hand, revisit them and demand a) your money back. b) a new film. This at the very least! There is precious little excuse for this with home processing. There is absolutely NO excuse for this with a lab. I've been doing B&W processing at home for 52 years...I've had this happen once...about 20 years ago. Link to comment Share on other sites More sharing options...
richardw Posted April 14, 2006 Share Posted April 14, 2006 Hi, I once gave a b/w film to a pro photographer who is a friend of mine, his brother had a lab and so i trusted him for good results. I gave him two films, because I did not come to my darkroom for some months. To make it short, they ruined both films with nice landscape photos. I was very very angry. I learned that its better to wait and keep the film in the fridge for some weeks more and to develop myself than to have a hurry and ruin the films. someone told me that in the machines they use higher temperature to develop more films per hour. I don't know if this is good for the quality of the film. regards Richard Link to comment Share on other sites More sharing options...
a_petkov Posted April 14, 2006 Author Share Posted April 14, 2006 Quite a bitter experience indeed. And it is very difficult to scan the film as it is now. Do you know if the emulsion is likely to peel off, is it going to last less than a properly developed film. Link to comment Share on other sites More sharing options...
richardw Posted April 14, 2006 Share Posted April 14, 2006 Hello, the condition of the film is still the same, as it happened only to the grain and not to the "coat" of the film. regards - Richard Link to comment Share on other sites More sharing options...
erik scanhancer Posted April 14, 2006 Share Posted April 14, 2006 The very first B&W film that I ever shot reticulated in a pro lab. How they did it I don't know, but it was a kickstart to my own B&W developing. I've never had a B&W film developed by a lab again. And I never saw back reticulation.
