Preparation of Images for PDI Competitions

Guidelines for the Preparation of Images for Projected Digital Image (PDI) Competitions

1. Introduction

For its PDI Competitions, the Battle Photographic Society (hereafter 'the Club') uses projection equipment and software selected to give the most accurate representation of digital images in terms of colour, tone, fine detail and image sharpness.

DiCentra software (http://www.wilburimaging.com/wisoftware/DiCentra.htm), widely in use on the national Photographic Society 'circuit',  is used to organise the digital image files for these competitions.

In order to display your images in the most optimum way and to ensure that they are projected correctly, it is important to follow these guidelines exactly for the preparation of your digital files, as the software and projector are quite prescriptive in their input requirements. Failure to configure the files correctly may result in rejection of your images by the software or poor reproduction if they can be projected.

Please note that these guidelines are designed principally for PC users who use any of 3 popular image processing software packages: Photoshop Elements, Lightroom and Picasa. For other image processing software please consult the HELP tab in your specific application or go on-line for advice/help (use the search term 'Re-sizing images' with the name of your software application). For members with Apple MACs a different procedure may be required - please consult the HELP tab on your installed software and/or other Apple users in the Club.

2. Summary of Basic Requirements

The Software and projector are set to accept files with an aspect ratio of 4:3 and a maximum image width of 1400 pixels. The following maximum image dimensions result from this constraint:

Landscape: Width: 1400 pixels   Height: 1050 pixels

Portrait:       Width: 787 pixels     Height: 1050 pixels

Square:        Width: 1050 pixels   Height: 1050 pixels

A folder in your name, containing the image files and completed  entry form, stored on a USB (pen) drive, labelled externally with your name, should be prepared. Exceptionally, entries may be submitted using a CDROM or as an Email attachment, by prior arrangement with the PDI Secretary.

3. Detailed Guidelines

See:

Appendix 1 for Photoshop Elements

Appendix 2 for Lightroom

Appendix 3 for Picasa

It is strongly recommended that your competition entries be saved in a separate folder (e.g. on your Desktop) to avoid the possibility of overwriting your original images with the considerably smaller and lower quality PDI files.

Each File Name comprises an Entry Number (in the format 01, 02, 03 etc) and the Image Title. These 2 components must be separated by a space:

E.g. :

01 Winter Scene.jpg

02 Springtime.jpg   etc., etc.

Entries should be submitted on a USB Flash Drive (1 per Competition) in a Folder labelled with your name (including distinctions if you wish e.g. Joe Bloggs  FRPS) Please ensure that you have deleted previous competition entries.

Open this folder and copy your entries into it.

          Please include the Standard Club Entry form in this folder - See Appendix 4.

USB Drives must be handed to the PDI Secretary or his/her representative on or before the entry deadline dates as specified in the Program/Club Rules and must be clearly marked externally(e.g. with a tag or label) with your name to ensure safe return on the evening of the competition.

The same preparation and storage guidelines apply if you are submitting entries on a CDROM. In this case please write your name on the CDROM and ensure that previous competition files are deleted.

If agreed in advance with the PDI Secretary, and in exceptional circumstances, you may submit entries as Email attachments via the PDI Secretary's Email address with BPS - Competition Entry in the Subject line. You will receive a confirmation Email on receipt of your entry.

4. Entry Requirements for the Annual PDI Portfolio Competition

Six images are required to be submitted for this competition and a modified File Labelling is required within your folder. Each image has to be labelled as follows:

Image number (01, 02...06), space, Portfolio category (in CAPITAL letters), followed immediately (no space) by a semicolon (;)  and Title. For example:

01 CREATIVE; Bringing in the Catch

02 ACTION; Whoa-here we go!

03 CANDID; Easy-peasy etc. etc.

N.B. Some CD writing software will refuse to burn file names containing a semicolon(;).

5. Virus Scans

Please ensure that your entries have been scanned by your fully updated virus scanner software prior to submission.

6. Copyright

The Copyright of images is retained by the photographer. However, Club members will be deemed to have given Battle Photographic Society explicit permission to hold their images on the Club's electronic storage media and for the Club to use them, if selected, for external competitions, unless they formally notify the PDI Secretary in writing of any particular image for which this permission is denied.

Click OK button. Click File, click Save as.

Appendix 2 Lightroom 5 (and earlier versions)

Open Lightroom, Click on 'Library', Select image to be exported, Click on 'Export'.

When the 'Export 1 file' box opens - see screen shot - decide on Export Location and File name where you want to store the image, prior to copying it to the USB memory stick.

For Portrait format: set W to787 and H to 1050

Set Resolution box to 300 pixels per inch

Click on Export button to export the image in required format.

Appendix 3 Picasa

Resize by exporting

Use the Export tool in Picasa to resize your photos or to otherwise create copies of your photos with all edits applied. When you export a photo in Picasa, you're creating a new copy of that photo with control over both the image resolution (the height and width of the image measured in pixels) and the image quality (JPEG compression). The original photo on your hard drive is never altered. Follow these steps to export copies of your photos:

  1. Select the photos that you'd like to export.
  2. Click the Export button in the Photo Tray.
  3. In the 'Export to Folder' window, select your export settings:
    • Choose an export location and enter a name for the exported folder.
    • Customise your exported image size and quality:
      • Image size options: You can choose between using the photo's original size or selecting a custom pixel size using the slider. The number of pixels that you select with this slider determines the length or height of your photo (whichever is longer). The other dimension is determined automatically to maintain the aspect ratio of the photo. Note that only limited, specific pixel settings are possible  viz.: 640, 800, 1024, 1200, 1600 (Max)                         
      • Image quality: Select the desired image quality for your photo using the Image Quality drop-down menu
        • Automatic: Preserves the original image quality
        • Normal: Balances quality and size
        • Maximum: Preserves fine detail for large file sizes
        • Minimum: Yields some quality loss for small file sizes
        • Custom: Enables you to select your own value
