New header picture.

As you can see we have refreshed the header picture and title with some fancy Text. I have been wanting to change this picture for some time but could not make up my mind as to which picture to choose. Until recently. Funnily enough It's been on display in the lounge for months. Even as a test strip I find it engaging. I have had a number of test prints over the years that I feel have worked better as an incremental image than the final result, so I thought why not! it is in keeping with the ethos of the blog.

The picture is of our 'trolley' sticking his head out of the rear window of the car. He is exceptionally pleased with himself as he has spent the afternoon up to his ears in water and soft gluttonous mud. So much so that instead of being tricolour his fur is slicked down with brown mud so badly he looks like he has used styling gel. Fortunately for us the back seat is covered with several blankets for times like this.

For a dog that loves to play in the water all day I find it strange that as soon as a bath is mentioned he go's and locks himself in his cage and then plays up no end when he is in the bath.



The picture was made using a Bronica SQAi producing a 6x6 negative on FP4+ developed in ID11. It is printed on Kentmere Paper 9.5 x 12 developed in Ilford multigrade. It happens to be one of the first batch of photographs I produced with this new paper. 
 
 
Recently this wonderful individual passed away.
 
He was a kind, cheeky, mischievous and above all of this very happy. He has been a painful lose.

Thinking in Black and white?


I don't know about you, but I find it difficult to get back into the swing of things after a break. I find it hard to get my brain out of park. It would seem that the longer I get in the tooth the more likely I am to make the silliest of mistakes. Take earlier in the year for instance.




One Sunday afternoon we thought we would take a trip out to the Humber bridge. The day had turned very warm with a light breeze and rolling clouds. Ideal for making pictures. Earlier that day I had cleaned my SQAi and loaded up all my film backs with fresh film. Not unusual in it's self, except one of the backs was loaded with an out of date colour film. I placed this back on the camera and thought no more about it.



It was a great day to walk across the bridge and along the way I made pictures of whatever took my eyes fancy, happy in the knowledge that they would make good mono-prints. After making twelve pictures I changed the film backs with one loaded with FP4+ and continued on my merry way.



When unloading the film backs at home I discovered that the unmarked back had colour film in it and not the Foma 100 I thought I was using. Ah! How would these pictures work in colour? The reason I ask this is because I think and see differently when using black and white film. Or do I?




An unexpected chance to test what I have been saying and doing. When the pictures came back from the lab, the first thing I noticed was the way they had been composed. In fact the colour does not add anything to some of the pictures. I would not have made any of these pictures in this way had I known it was colour film. It would have been a different set of pictures altogether.

Choosing an enlarger.


This is the most important tool in the darkroom after the enlarging lens. With this in mind you need to consider the following: 

1.   The number of negative sizes you may wish to print. It is a good idea to get a multi format enlarger even if you are only going to use 35mm.
2.   The most appropriate lens size and quality.
3.   What type of negative illumination. Diffuser or Condenser.
4.   The maximum size of print you are likely to make.
5.   Whether you may want to do colour at a later date. Colour headed enlargers can be used with multigrade papers. 

As mentioned in “3” the type of negative illumination you choose is worth  a lot of consideration -  there are positive and negative points to both. Here are some of the pros and cons: 

Diffuser enlarger: 
Diffuser light box
This type of enlarger design is used with colour and multigrade heads. The light travels through a mixing box and semitransparent screen above the negative. To counteract the drop off in light, these enlargers use a powerful quartz-iodide bulb.  This multi directional light passes through the negative and down to the paper. The affect of this will produce a gentler, softer quality to the  light, producing a less contrasty grade for grade photograph. As a result damaged and flawed negatives lose or soften some of their faults. 
There are tonal differences between diffuser and condenser produced photographs because of the way light passes around the silver particle's. This is negated when using Chromogenic monochrome and colour films as they rely on dyes to capture the light. 
Condenser enlarger: 

Condenser light box
Uses a plano-convex lens which spreads a bright hard illumination  evenly across the negative. Supplied from a opal tungsten lamp. The harshness of this light produces a contrast enhancement that appears to make  fine detail more exaggerated. This crisp appearance to the photograph has the negative affect of bringing into sharp focus the grain, any scratches, flaws and dust from the negative, meaning more time spent on retouching. These enlargers are subject to the Callier affect this is where the highlights in the negative scatter the light more than the shadow areas creating the increase  in contrast.

Enlarging a section of the negative.

Landscape format
There are no rules when it comes to enlarging your negatives. Cropping, re-formatting and partial enlargement are all part of the creative process. Changing horizontals to verticals and diagonal is also part of this rich tapestry of creativity. The only time I feel this looks odd is with waterscapes and their horizons.
Portrait format





As one of those people that works with 6x6 negatives, cropping and reframing is all part of making the picture fit the paper. I'm not complaining but the fact is all paper sizes are oblong. I think this has helped me in getting the best from my pictures. I do not waste time in trying to make the whole negative fit the page; this is heresy to some who believe that having carefully framed the view that you should print as you saw it! This is not always possible, especially when you have a certain size of print in mind. Sometimes this careful framing once projected on the enlargers baseboard may look better with horizontal or vertical framing. Do not be afraid to play.

Square Format
Which do you prefer?

Contact printing.


Now that you have your negatives safely stored and indexed, you need to sort out which negatives you are going to print. Trying to judge this by holding them up to the light or by laying them on a light box can be difficult. The best way is to produce a contact print showing all the frames on one sheet of photographic paper.

There are special frames that allow you to do this. You can buy contact print frames which consist of a glass top with film holders attached and a solid base with foam on that clips shut. For 35mm or 6x6 (medium format) which hold seven rows of six for 35mm or four row of three for medium format negatives. The frame holds the negatives so you can see the frame numbers on the print, you place them with the shine side up and put a soft grade light-sensitive paper on the base. Then shut the frame to bring the negatives in contact with the photographic paper, hence contact print.
Another method of contact printing is if you use clear plastic negative holders, you can place these directly onto the photographic paper. The problem with this method is it does not hold the negative completely flat to the paper which means that some of the pictures may be distorted. A way round it is a clean sheet of glass that is big enough to place over the negatives.

Enlarger


An enlarger consists of:

Enlarger for 35mmm negs
only. with out multigrade
head. Condenser type.

A baseboard on which enlargements are made; a column, which serves as a slide for the support arm, that holds the enlarging head, which consists of the lamp housing that contains the bulb; a single or double condenser; negative carrier, a place to fix the lens; a means of focusing and lastly a red filter that swings in front of the lens.

The lamp contained in the light housing is of the opal type and has a power output of 75, 100 or 150 watts. The pearlescents of the bulb with the help of a condenser distributes the light evenly across the negative. The lens focuses and projects the negative image on to the baseboard or rather an easel with paper on it. The higher the enlarging head is from the baseboard the closer the lens is to the negative the greater the magnification. The closer the head is to the baseboard the greater the distance the negative is from the lens the smaller the magnification of the picture. The typical focal length of lens for 35mm negative is 50mm and for a medium format (6x6) is about 75mm.
A multi format Enlarger with multi grade head.
Diffuser type.

The negative is clamped in the carrier which incorporates a mask that is the same size or format as the film and then placed in the light box. It is not a good idea to cut the negatives into single frames, it is better to leave them in strips to make it easier to line the frame up with the mask in the carrier, this also means you are less likely to scratched them.


Focusing is usually done manually, although there are enlargers available with automatic focus, these are usually more expensive.
