Scanning images
Before beginning to digitise it is important to develop a digitisation plan to establish why images are being digitised, how will the the digitised image be used, which images will be digitised.
Detailed information on digitisation and digitisation plans can be found on the blog Information technology and local history. Select the Digitisation link to view relevant articles.

Backing up images
Digital image collections can be backed up on to CD-Roms or DVDs. USB drives are also useful for backing up files. Portable hard drives are another useful medium for backing up files.
It is important to remember that all of these devices, like floppy disks which preceded them, may fail so do not rely on one source for backing up files.
More than one back up should be made.
At least one back up should be stored off site.
In the future it will also be easier to store images online - a number of sites are already providing this service for a fee and no doubt there will be further developments in this area.
Including records in online image databases such as Picture Victoria, as well as making the images available to the public and promoting your collection, also serves as a way of backing up low resolution copies of digital images.

Cataloguing postcards
Many historical societies have collections of postcards - some showing scenes of their town and surrounding area while others were collected by families in the area and can be a valuable source of social history.
The RHSV has a collection of more than 3,000 postcards. Some of postcards produced prior to 1955 can be found online in the Postcards Online database.
In 2002 the Royal Historical Society of Victoria held an exhibition - Travellers' Tales: Photography & the Proliferation of the Postcard an exhibition showcasing the range of postcards held in the RHSV collection, particularly those produced in the second half of the nineteenth century and early twentieth century. Themes in the exhibition included Promoting regional Victoria, Promoting Melbourne, Victorian landscape, People and landscape, Pioneering life, Promenading on the pier, Sport, Hotels and guesthouses, Disasters and Decorating postcards (for Christmas). An online exhibition based on the 2002 exhibition was created in 2007.
Postcards can be catalogued in the same way as photographs. Descriptive fields can include Registration (Accession) number, Object name [Photograph], Title, Brief description, Subjects, Photographer (may include company producing the postcard), Date made, Size, Location as well as the usual fields relating to donor, condition etc.
In the brief description describe the scene in the postcard. At the RHSV we are also including a transcription of the message on the postcard.
As well as descriptive subjects for people, places, buildings, objects etc in the postcard, subjects can also include the name of the person/ people on the back postcard, if full name known, and any themes that you might like to use to group similar postcards. For example many postcards were sent home during the the First World war so World war, 1914-1918 could be a heading. Many postcards were kept in scrapbooks so if this is the case the name of the collector could be a subject heading.
If the datastructure has an Address field and the full address of a building is known this information can be included - town / suburb, street, number.

IMUG meeting June 2008
Barbara introduced the session by taking a photo using a digital camera, transferring the image to the computer and then linking the image to a record in DB/TextWorks. Susan Oliver from Werribee Park and Werribee & District Historical Society told the group about projects, undertaken at those organisations, to attach images to their catalogue records.
In her talk Barbara spoke about resolution and compression of images and different file formats. She showed how to link the image by typing the path to where the image is stored on the computer (or elsewhere) into the image field in the edit form. In the discussion a number of people said that when adding images to a batch of records they copied and pasted the path into the image field and just changed the name of the image.
From version 4 onwards it is also possible to scan a photograph and link the scanned image to the record dirctly from the database. Click in the image box on the Edit screen, go to the Records Menu and select Scan Image then follow the prompts. When the image is scanned and stored the path is added automatically to the record.
Another tip that Barbara gave us was that it is possible to specify the drive where images are stored so that the database will automatically check the drives nominated to locate the image and the drive does not have to be added in the path. This feature can be found by going to the Tools menu, select Options, select Imaging, then in the Image drives box type the letter of each drive where images are stored. Click OK to complete the action. There is additional information about this in the Imaging Tab (options) in the Help index under Image drive and path.
Barabara also showed how to add a picture box to any report form in order to view the image with the record.
The Help in DB/TextWorks is acually helpful. Searching for Image in the index should answer most questions about using images with the database.
At the end of the session Barbara showed how to make a simple lightbox for reducing the shadows and improving the quality of images when photographing small items. How to create an inexpensive photography lightbox and Do it yourself lightbox are two of the many articles available online on this topic.
