Preserving photographs and other visits.

I visited London recently and made a visit to the British Library in Euston Road. This was a planned visit as they had various exhibitions on at the time, including photographing you dressed as a Victorian if you wished. They produced a series of lectures, and I attended the one about preserving photographic material, which was quite fascinating. They have a Preservation Advisory Centre, which covers a wide variety of subjects, one of which is "Photographic Material", and I make a few notes below to this effect. Although the note below refer to non-digital material, the same comments apply.
Preservation of photographic material.
Preservation is a relatively new specialism and treatment options are often limited, but it is possible to prolong the life of a photograph good preservation practices in handling, housekeeping and storage.
What is a photograph
A photograph is an image produced by by the action of light. The support is usually made of paper, plastic, glass or metal, but sometimes on leather or cloth. Photographic images are usually continuos in tone, meaning changes in shading between light and dark are gradual and patterns such as regularly spaced dots or grids are not usually seen. Images produced by photomechanical processes for books na dnewspapers are non-continuous in tone.
Causes of deterioration
Photographs are particularly vulnerable to physical, chemical and biological damage and deterioration. Handling, poor environments and low quality storage materials (eg papers) all have an impact on the condition of photographs. Images created through certain photographic processes are more sensitive than others, but all photographs are sensitive to poor environmental  conditions. High temperatures, high relative humidity will cause fade and discolour. Light can also cause fading.
Handling photographs
When handling photographs always work on a clean, clear surface of sufficient size. The area should be clean and dry, as dirt can scratch any photograph. In order to minimise damage here are a few tips:-
*      Photographs should be handled as little as possible
*      Provide a copy print if possible
*      Supervise anyone who handles the photograph
*      Hands should be clean
*      Use two hands to hold the photograph
*      Do not eat, drink smoke over the photograph
*      Do not use ink to label the photograph, use an HB pencil on the reverse, and do not press hard.
*      View under UV light if possible
*      Do not stack photographs one on top of the other.


Housekeeping
Simple steps can be taken to improve conditions for photographic materials.
*      Monitor and control the temperature and relative humidity
*      Regularly check for damage
*      Remove of damaged and store separately
*      Keep areas clean
*      Avoid using household cleaners
*      Do not store photographs in direct sunlight
*      Do not store near photocopy machines as they emit ozone which will damage the photographs



Visits
I have not made many visits recently, but I did manage a trip to London and got to see the Taylor Wessing Portrait exhibition at the NPG. This is always a very good exhibition, and to see a good selection of contempory photography is always good. I sometimes don't always understand how some images are chosen, but nevertheless I can always learn something from them. Generally it is the lighting but sometimes the explantion is needed to understand why the photo was taken. Lighting always seems to be the key, which brings out the character of the person, whether one light, 2 lights or more, and natural light used creatively.
Also the NPG had an exhibition by the painter Thomas Lawrence (1769-1830) entitled "Regency Power and Brilliance". He was the leading portrait painter in Regency Britain, starting at just 21, and the paintings were exceptional in alot of cases. his use  of light ont he portraits was immense, and I think I enjoyed this exhibition more than the other. This may have been due to the majesty and size of the paintings, but remembering photography was not invented until about now in some form, then this is how the mainly rich and famous would have had their image portrayed. It was an excellent exhibit to go with the Taylor Wessing, showing the contrast between the two ways of presenting people. But, due to rearch for other parts of this course alot of the early photographers, and not so early were previously Painters, and photography became an extension of this. I add here that art was my favorite subject at school, but then I could not aford a camera, although I had my first one at 10.
Also on at the same time was the the "Landscape Photographer of the Year" exhibition at the NT. This is also such a good exhibition to visit. Again the winning images were good examples of the use of light as well as composition and being able to direct the viewer to the scene the photographer wanted him to see.


Books
When I was wandering along the South Bank over christmas the footpath was diverted due to the building of the new station at Blackfriars. This led to a diversion and passed an art book shop. I just popped in to see what there was available, and on the floor were 3 stacks of catalogues for sales of photographs. These were From the likes of Christies, and were from diverse places as New York, Rome and London. The catalogue prices ranged from €75 and beyond. However they were for sale from £2 to £4 remarkable value for the the contents. I bought 3 for a tenner and they include so many images from famous photographers, from Edward Weston to Man Ray to photographers I had not heard of. the prices are listed for auction purposes, and are quite staggering for some, up to $1800 or more. I shall go back and get some more as they are quite inspirational, and full fo ideas, both old and modern.

310 - printers

There is such a great market for printers, at so many different types and prices, it can very difficult to decide which one to choose. Dot matrix, ink jet, and laser being some types, either colour and/or black and white.
The choice also very much depends on how you are going to produce your prints, and this should be considered prior to your your shoot, and to fit in with your client brief should you have one.

The variety of printing methods today is vast (for digital printing) as is the surfaces to which you can print. These vary from your cheap supermarket papers to archival papers, to aluminium and acrylic, from photographic papers to canvas. Your image can look very different depending on the surface it is printed on. There is also the choice of Matt, semi matt and Gloss for instance,and some in between.
I tend however to send my printing requirements away to an on-line printer as the results are so much better.

The major consideration today is the cost of the inks. When I visited the professional studio of Paulo Loroso the main consideration in the final print was the cost of the inks, and this was the most expensive part of his (or any other photographers business) business. Some businesses offer only CD's/DVDs for the client to take away, and let them print the ones that they require. However there are other mediums to consider, such as the web, and maybe the reuirment to print from this.

My home printer is an A4 Epson stylus PHOTO 220R printer. It uses Epson's unique Micro Piezo print head and 6-colour inks. The prints can also be made borderless on formats from 10 x 15cm to A4. With a resolution up to 5760dpi on suitable media. It has the ability to print on CD/DVDs. You can also apply effects, change layouts and add frames to the photos, with the included range of easy to use software. It is PC and MAC compatible, and has the Epson Print Image Matching III for faithful photo reproduction. The printer produces acceptable prints using the Epson Inks, which tend to be expensive. I have also used Epson papers previously to produce my prints, as the inks are matched for this make of paper.
The technical specification follows:-

Below is one aspect that needs to be checked with any printer, and that is a nozzle check.



 

I do not generally use this printer for producing photographs as the quality is inconsistant, and generally not up to gallery standard, and only being A4 and I have not been able to calibrate this printer due to the software being expensive.

Generally I use an online printing outfit for my larger prints. This is a company called D S Colour Labs Ltd,  working in association with Fujifilm. They offer the full range of services from Prints through to photobooks to acrylic panels and photoflyers, and a whole range of gift ideas.
They use Fuji Frontier 570 printers, and all images sent to them are using their printer profile that they have sent. Images can also be supplied as sRGB. Below is the monitor calibration chart that they supply. This is also a crucial part of the printing process, as you want to get a print that replicates what you see on the computer screen. details for this are noted elsewhere on the blog.


The printer is Fujifilms most popular high volume digital lab system,and with high processing capacities can produce prints in minutes. I have them delivered next day by post. Below is an illustration of the printer.



The specification for this printer is very technical and is not included here, but I have a copy as a PDF on my laptop.
There are many alternative suppliers of this facility, and at varying prices. I have chosen this lab as to date it has produced the best value prints, which is very important in todays economic world. I would add however that I will investigate other sources of printing depending on the final destination of the images.

The other current option is to use the printers at college. This printer is an HP Photosmart B9180 and is aim ed at the professional and creative market, launched Feb 2002..
It has 8 ink cartridges, Matt black, photo black, light grey, light cyan,cyan, light magenta, magenta and yellow.(similar to my home Epson printr but has 2 more black inks). The print quality for colour is up to 4800 optimized dpi colour (up to 4800x1200 dpi colour when printing from acomputer and 1200 input dpi).
Below are the sheets that were printed from the printer I used to submit my final images from.

this is the printer calibration sheet

this is the print quality diagnostics page

The paper used is HP Advanced injet paper (satin-matt) at A3+ 250g/m2, and is top gallery standard.
My personal preference is to use the college printer, as it is calibrated through from the Mac screen to the final print, and gives me the print that I want, and will last, given that it will need mounting correctly, with the appropriate frame and glazing.
