The conservation of photographic materials is central for managing an archive. Conservation work consists of: monitoring environmental and physical conditions and implementing precautionary and conservative activities to minimize the negative effects of external agents on the photographic materials.

1. PHYSICAL CLEANING

The photographic material is very fragile and can be attacked by damaging agents. We can classify them in three categories.

# Biological agentsMoulds, mushrooms and insects.

## Chemical agentsLight and air pollution.

### Physical agentsFlooding, weather events or various physical shocks. Furthermore, the photography can bo damaged by poor management.

For the physical agents you can protect the pictures through a cleaning process, however for biological and chemical damage, specific restorative work must be carried out.

Work tools

# Cotton or latex gloves To avoid contact between greasy skin of hands and photographs.

## Velvety microfiber clothTo clean.

2. ACCESSION NUMBER

To make an Inventary you need to number the photo and place it in the archive.

Repository

Name of Repository

PlacingLetter and number of the box that contains the photo.Every box will be named with a letter (A-Z) according to its size, follow an increasing order.

Call numberIt’s the number that identifies the photo.

3. CATALOGUING FORM

This phase consists of compiling the “Scheda F” (database), digitalizing the photo, and putting them in the neutral paper envelope (PH neutral).So it’s possible to see the photos in digital format without the necessity of accessing the photo itself. This way it’s easier to access and consult the photo by author, topic, technical information, size, chronological period, …

4. DIGITALIZING

To digitalize pictures you need of a scanner, flatbed or drum.Generally a flatbed scanner of good quality is sufficent.In professional sector (such as paper publishing), we often go to external services that use a drum scanner.

SizeFor archiviation use, you should digitalize the images in the same size (cm) of the original support.

Size for webTo upload the images on websites you’ll need to consider the pixel size (px).

ResolutionRefers to the quality of the image. Its indicates the density of the point in the image and it’s measured in dot per length: dot per inch= dpi.Remember that during the acquisitions is necessary to scan the image to the resolution sufficient for the purpose.

# Monitor > 72 dpi > Low resolution # Print > 300 dpi > High resolution

ColorThe main color spaces used in digital acquisition images are RGB (monitor, projections and photographic print) and CMYK (industrial print).

# RGB > Red / Green / Blue Additive color system Color profile recommended Adobe RGB

5. STORAGE

To store the image files remember to use Accession number.Any photograpic catalogue stores the same photo file in two different resolutions: high resolution for duplication or reprint; low resolution for web consultation or database preview.

How to work

# Scan the photoRGB profile, 300 dpi resolution, Original dimension

## Save photo on your Hard DiskFile name from Accession number: F_ABMC_A_0001_0000852.tif

### Edit the photoOpen file in a image editor (Photoshop, Gimp, …), and use the command “save for web”.

Size for orizzontal photo > base 800 pxSize for vertical photo > base 500 px

File name: F_ABMC_A_0001_0000852.jpg

The generated image will have automaticaly a resolution of 72 dpi.

#### Folder StructureTo avoid overwrite file pay attention to where you put your file.Path High resolution > Dropbox/HH-catalogue/Group01/HR/Path Low resolution > Dropbox/HH-catalogue/Group01/LR/
