Photographic prints are intended to be viewed and when looked after can remain in excellent condition for over a century. However, as they are paper-based they are prone to damage if mishandled. Caring for a print A print intended to have a long life should be processed by methods recommended for long-term stability. If necessary it can be retouched to eliminate blemishes. Prints that are going to be displayed should be mounted, framed and glazed to complement the image and protect it from deteriorat...

Retouching is normally done to remove blemishes from the negative or the final print. It can also be used to change the tone or remove unwanted detail.  As retouching can be difficult, care is required. Advice for retouching The most risky retouching techniques involve removing parts of the image, by bleaching, cutting, or scraping with the edge of a sharp knife. The addition of density is generally less risky, and can be done using dye, paint etc, or a suitable soft pencil. When retouching prints from o...

A black border often enhances a print and does not involve any sort of mounting or overlay. Ink or tape borders The easiest way to produce narrow black borders is to rule them with a pen directly onto your finished print: an India-ink pen gives the most solid line, but most permanent (all surface) spirit based markers are much less expensive and will do the job. For slightly wider black borders, narrow, self-adhesive strips are available from graphic arts suppliers. Supplied in dispensers, of various w...

Mounting your Prints Even the most stunning print can look better when it has been properly mounted. Mounted prints are also better protected as they are kept flat with the image separated from the immediate surroundings by unobtrusive margins. There are no hard and fast rules about mounting prints; the most suitable results will depend on individual preference, the nature of the image, the intended use and other circumstances. It is recommended that only boards and other materials intended for the p...

Testing your Safelights Safelights are an essential component in any darkroom set up. We recommend testing them annually, as ageing can change the transmission characteristics of the filters. This can cause visible fogging of the print or, more likely, a subtle but noticeable drop in contrast. When setting up your safelights always read the instructions and don't exceed the recommended bulb wattage. Fitting a brighter bulb or mounting your safelight too close to your developing dishes,  may cause degra...

The ILFORD PHOTO Archival Sequence, or Optimum Permanence wash system is a method of processing fibre base papers for maximum longevity while reducing the amount of water and time used. Whilst standard fixing and washing recommendations will give excellent print permanence for all commercial needs. When optimum permanence is needed, perhaps for archival storage of prints, the following fixing and washing sequences at 18–24ºC/65–75ºF (including wash water) are recommended using ILFORD WASHAID. Fi...

Split grade printing The version of split grade printing described here is that taught to me by the ILFORD head printers, Mike Walden and Terry Offord, and is the simplest, fastest way to make good darkroom prints from pretty much any negative. (The exception is really underexposed negatives to print these you usually only need high contrast). This is a very powerful technique that can be used routinely with variable contrast (VC) papers, such as ILFORD MULTIGRADE. It makes use of the differing performa...
