Welcome to the New Year

 On a grey and dull day I am going to say a big, bright THANK YOU to all my follows, subscribers and supports for visiting the blog over this last year. Views are up big time even though it has been a bad year personally.

As is the custom for this time of year I have a new header picture that shows a hand picking up or putting down an Agfa Isolette I will leave it up to you how you interpret my intent. If any of you have any suggestion please share your thoughts.

As I sit here writing this, it is peeing down with rain, which has inspired me to set up my pinhole camera to make an image that will take eighteen minutes to expose. Not the longest exposure I have made but getting there. This is  the start of my rediscovery of the wonders of  pinhole photography and the Zero camera in   articular which I hope to use more this year  instead of leaving it in the camera bag. A new   years resolution of sorts!

Talking of new year resolutions photograph wise -  have you set any? I don't as a rule but this  year is  going to be different I have two things I  could like  to achieve one I have already  mentioned the  other is to spend more time in the darkroom  printing, something that I can neglect. I find it  difficult to spend anytime at all during the  summer months in the darkroom I  o not like  wasting time inside if the weather is  bright and  warm, even in the evenings. I  suspect I'm not the  only one. What are your thoughts? 

I'm looking forward to seeing you all again this year. Don't be shy if you drop by - have a chat (leave a comment) - always interested in what you get up to. I shall leave you now as my mistress the darkroom is calling! I will chat with you all again later. Before I leave I would like to wish you all the best for the year ahead. 

Living with Tetenal Eukobrom AC

Developer

Tetenal new Eukobrom AC is proving to be a delight to work with. I did not realize how much of a irritant the smell of the developer was until it had been removed from the equation. I no longer have developers nose where the smell lingers long after I have left the darkroom. 

In an early article on this developer I had a couple of questions: Personally the main questions yet to be resolved are its keeping qualities and whether or not the image will be warm when the developer starts to deplete. One of these has now been answered, that is it's keeping qualities. I have been using it in my slot processor, at the end of each print session I leave the developer in the slot and cover it with the lid. The amount of time between each print session varies a lot from days to weeks sometimes months.

Slot processor

 Two things have come to light. If you leave the developer in the slot you should give it a stir before you start using it again. The active ingredient can separate out dropping to the bottom. I was caught out thinking that the developer had come to the end of it's working life because it had been left for two weeks. Something I did regularly with Ilfords multigrade without loss of usability.

Something else I have not experienced before was a black and white crystalline substance on top of the stop bath. It was a very heavy build up making it difficult to remove the top off the stop. The stop it's self was clear and still at the level it had been left at, turning out to still be working even so I changed it. This maybe an interaction with the vitamin C - something to keep an eye on.

The other question about the warming of the prints as the developer depletes still remains unanswered. This due to the fact I have not processed enough prints with the fresh developer. Once I notice I'll let you know.

 

Finally I have used this developer with a number of makes of paper now - RC and FB, natural, warm, cool tone and tinted papers - With great results, so if you have not tried it yet, do so! you can get it in 250 ml shots which is More than enough to get a feel for the way it works and looks.

One day later

I don't know about you but sometimes my mind wonders when I am processing photographs in the darkroom. I just can not help it, especially when an FB paper is involved, as sometimes it can be minutes till it is fully developed.

It was on one of these occasion that I started thinking about how long it would take for a developed image, but not fixed, to disappear. I have always thought it would be seconds once you turn on the light. Don't ask me where I got this notion from it is almost folk law among film uses. It is known that if you accidentally do it with film it all go's black straight away. Well the truth is, it can be saved if you are quick.

So what about photo paper? Firstly unexposed paper go's pink in day light and not black as I was expecting. The longer it is in the light the pinker it gets till it go's a pinky brown colour.

OK! a developed but not fixed image also degrades the same way but the image does not fade to black ether. In fact there is not much change a day later if left out on the table.

What is the biggest surprise of all nine months later and the image is just visible. You must bear in mind that it has not been in full day light all the time. I did notice that it had a couple of books on top of it for a time. It has well and truly surpassed any of my expectations. Just go's to show what you think you know may not bear any relation to the facts.

Technical data:

The images have been enhanced to help show the colour change digitally. The test strip appears in order of age from a couple of days to the last one nearly a year old and still going. I like the effect it has produced on the test strip. The paper is Ilford FB natural gloss. Developed in Ilford multigrade and washed, no stop or fix was used.

What image looks like when processed

What can Contact prints tell you.

I have written on this subject before outlining the advantages of making a contact print for your negatives. The subject has come to the fore because a recent example shows that the negatives are poorly exposed and possibly have a higher than normal amount of contrast.

 So where to start? With the sheet of negatives. The first thing you notice about them is that they are well developed with good tone and detail but on the dense side, meaning they could be over exposed / developed. Something that can sometimes be difficult to judge from the neg's only.

 

The contact print is saying that the negatives are well and truly over exposed and or over developed meaning that to get a balanced image is going to require a longer than normal exposure. It is also suggesting that the images are hard (a lot of contrast) How much will not become apparent until the segmented test print has been produced.

My normal exposure set up for the enlarger is F8 at grade 3 this is my datum point to which I judge how well I have exposed and developed the film. The first test print confirms that the negatives are very over exposed, requiring a second test because the results are so weak. I must admit that I was a bit blasé with my pinhole camera exposure times. This camera tends to bring the worst out in me when it comes to proper control but then it is all part of the fun.

I have already compensated for the longer exposure time by opening up the enlarging lens to F5.6 doubling the amount of light I would usually need. I also know that the contrast is higher than normal from a previous set of exposed photographs. It is to do with the Studional I used to develop the negatives in. A previous session showed that the softer grade 2 would give better results.

Without the contact print I would have spent much longer in the darkroom making test prints to find what the base exposure should be, if I had not been pre warned. It also indicated that the completely white looking skies would require a lot of burning in to bring the detail out shown on the negatives.

For me making a contact print ensures that I get the most out of my printing session. It allows me to preplan what I need to do to get the best out of each negative without wasting a lot paper and time. The later for me is always in short supply.
