Submitting Digital Images - What's Required??

As part of your project, you may wish to send us digital images of the site or sites you have been recording, and you may also wish to display these on the SRP website. By 'Digital Images', we mean digital photographs and scanned version of your drawings, plans or printed photographs of the site. We have prepared the following guidelines to outline the main requirements for submitting digital images to both the SRP website Project pages and the On-line recording form, for submission to the RCAHMS database.

Minimum file sizes for all digital images should be 1-2 MB but ideally images should be larger than this. You will be able to submit images of up to 8 MB to the RCAHMS database using our online form.

Choose the images you want to submit carefully and make sure that they have appropriate captions, as images without captions cannot be accepted.

There is no limit to the number of relevant digital images you can post on the SRP website (within reason), but there is a limit to the number and size of images that can sensibly be submitted to the RCAHMS database. Ideally aim to submit no more than 10 good images that depict your site and its setting. Remember that sites comprising only one building may only require a single photograph whereas as more complex sites may be better captured with several different photographs. Try and aim for quality rather than quantity!

Photographs should all be in JPEG format.

Scanned images (e.g. of site surveys) should be between 300 and 400 dpi (dots per inch) / ppi (pixels per inch) and saved as JPEGs.

Detailed Notes

There are three main file formats used by digital cameras to create images; JPEG, TIFF and RAW, the most common being the JPEG file format. On many digital cameras it will be the only file format available although more sophisticated digital cameras will allow you to choose between JPEG, TIFF and RAW.

TIFF file format is the preferred choice for archiving images as it keeps the original quality of an image over time. However it takes up a lot of file space compared to a JPEG image and takes longer to upload or download.

Please do not submit RAW files, as most image editors cannot open them!

The preferred settings have been chosen to allow content to be stored at an archive standard and also to allow reproduction at a scale suitable for printing and display purposes.

The preferred file format for all digital images whether produced by a digital cameras or other source (i.e. scanned image) is JPEG.

Most cameras give a quality option within the menu of Small, Medium and Large. In order to produce high quality images, you will need to set your camera on the large or medium option in order top give an image of 5-10 Megapixels - as a JPEG this will equate to a file size of around 8 MB.

When submitting scanned images please try to ensure that they are between 300 and 400 dpi (dots per inch) / ppi (pixels per inch). Using these scanner settings a Black & White or Greyscale image at 300 dpi will be less than 2MB and an RGB Colour image around 4MB whereas this would rise around 4MB and 9MB respectively at 400 dpi.

The content and settings of all uploaded files will be validated by SRP RCAHMS staff, and will eventually become archived digital collection items in the RCAHMS Oracle database.
