NEXT MEETING …    ALL THIS SEASONS MEETINGS ARE CANCELLED.

 

All meetings (including End-of-Year AGM in May) are cancelled.  Our new 2020-2021 season traditionally starts in September each year but may be earlier or later depending on events.  Please keep an eye on our website for latest news and plans (including any web-based projects/activities during the current crisis).   

 

We hope to reschedule some missed meetings for later in the year and to hold our Annual Exhibition later this year.  We hope to be able to offer one or two activities via the internet.  We will keep members and potential new members informed via email and on the website.

 

POTENTIAL NEW MEMBERS…
If you think you might be interested in joining our friendly club once this covid-19 crisis is over, please contact us by email, phone or web form now.  We can then include you in our plans for when life gets closer back to normal.  We cater for all levels – beginners to very advanced/professional.

By the way, sorry if some of our jargon isn’t clear! We use PDI (Projected Digital Image) to mean jpg images that conform to our entry requirements which are simply those that fit into our 1600 pixels wide and 1200 pixels high maximum limits. We will have a pre-meeting workshop to explain all this at 6:45pm in the small committee room on our next club night, Thursday 26th September. Just turn up on the night and we hope to cover both PDIs and Print requirements.

[Note some clubs use the term DPI instead of PDI: we prefer PDI to prevent any confusion with “dots per inch”. (And for those expecting to be told to use a particular “dpi” such as 72 or 300, this value does not matter when used on our projector. If you are concerned set it to 300dpi.]

Even if you are not yet ready to enter any Prints or any PDIs, you are always welcome to have a go “to break the ice” or if you prefer, please just talk with Helen or Chris about the photos you might like to submit. There is no pressure to enter competitions (except perhaps for our light-hearted Ladies v Gents) but most people find entering rewarding and helps to have impartial feedback. Don’t worry if your early scores are at the lower end: we all do from time to time except for one or two extremely talented members!

As from September 2019, Shaftesbury Camera Club will be adopting the new PDI standard of 1600 x 1200 pixels that is being used by WCPF and many other clubs.  Fortunately the software we routinely use (Dicentra and Faststone) detects the projector native resolution and rescales on the fly to match.  This means a full 1600 x 1200 image will be rescaled downwards by exactly 10% to accommodate our 1920 x 1080 projector, i.e. the image will be presented as 1440 x 1080.

 

Notes for projector and laptop Feb 2020

  1. 2 socket extension lead plugs in below wall screen, attach to floor with tape. Low table at end of it with projector at front and laptop behind. Plug projector and Laptop through the hole in the table into the sockets.
  2. Switch on projector (back L) should show test card, make sure projector is at right angles to screen, test card centred and 2ins from top of screen. Lift front of projector with lens cap, focus (black ring) and zoom (white ring) if needed
  3. Laptop power lead goes in socket at the back of the Left side. Attach to projector at front of L side of Laptop and HDMI 1 on top row of back of projector. The laptop screen should go black and projector show the laptop ‘desktop’
  4. Remote keyboard (so you can sit comfortably at table). Switch L side give green light. Click F2 to sync keyboard to laptop: use the Windows ‘start key’ on bottom row to prove it is working. You may need to repeat F2 and start.
  5. Mouse switch under it, (you may need to use the laptop pad to get the cursor on the screen) the mouse should now work cursor but if it doesn’t you can see Bluetooth info via ‘start’  button and top left square on the windows screen.

If all else fails, you can use laptop anywhere with 3m lead in the projector case or 15m lead in the cabinet upstairs and a wired mouse in laptop case (wrapped in cling). This is useful for visiting laptops.

Note if using AppleMac you may need to change colour from RGB to YCbCr (YUV) on the projector. Menu/Image/Colourspace. Auto or YUV.

Dicentra and running competitions

  1. On Dicentra select required competition
  2. Top menu banner select ‘Competition’ and Run (or Ctrl R)
  3. Right click on mouse brings up Menu or (M)
  4. Use the keyboard R and L arrows to run through the images; for slide preview 3secs or see below.
  5. Scoring use torch to enter scores (.) for half marks  (H) to hold back and hit again to remove Held. To remove marks use back key
  6.  (N) is Navigator.  A button at bottom will give a slideshow useful for preview . It also will show ‘images missing marks’ and ‘held images’ and can show ‘all 10’s’ etc. You can select another bottom button to show things on the Light box.  You can check box at bottom to show names
  7. S gives final scores
  8. If things are ‘pinging’ try Esc
  9. Mouse to bottom of screen shows Images held back.

SCC has been invited by Blandford Forum CC to participate in a three club “Match-an Image” competition later this season. The last one of these was in November 2014 again hosted by Blandford where we came 3rd having won (… just) the year before: read our brief report here.

These notes are to help newer members to understand how this fun competition is run and to help them provide us with suitable images.

At the start of the evening, each club has to be prepared with 40 PDI’s loaded on their own laptop and projector. One club will then project one of their PDI’s as a “starter” image: the other two clubs then have a strict time limit of 30 seconds to select and project their “matching” image. The judge (who is often the victim of considerable good-natured banter) then has to award marks as follows:

  • The “starter” image automatically gets 1 mark
  • “Matching” images get 1 mark each if the judge agrees they match the starter
  • The judge awards a further 1 bonus mark to the best quality image from the starter and valid matches
  • If none are judged as matches, the starter gains a bonus of 1 mark

The three images used in each round cannot be used again in subsequent rounds. Each club takes it in turn to provide the “starter” image and there are a total of 30 rounds. Hence each club provides 10 starters and 20 “matches”, and will have 10 unused images at the end.

In addition to our laptop, projector and 40 PDIs, we will have our PDIs printed as contact sheet and clearly numbered to help make our rapid choice of matching images before the disqualifying 30 second time limit. Used images can be crossed through with a black pen. As a minimum on the night, we will need two members to choose the images, one to run the laptop and one to keep score. Additional members can help by challenging the unfortunate judge!

It should be clear that our 10 “starter” images need to be difficult for other clubs to find a “match” but our “follower” ones need to be general enough to match all sorts of others.

IMPORTANT! – Use a wired mouse for the laptop, not wireless or trackpad! Also keep a black screen.jpg in the starter and follower folders.

UPDATE May 2019: References to 1400×1050 changed to 1440×1080 to align the projection standard to the new Inter-club 1600×1200 pixel standards.  The no-input user-generated test image has been adjusted to facilitate easy alignment for both 16:9 and 4:3 formats using the full 1080 height.

UPDATE Nov 2018: Noted High contrast edges, e.g. trees against sky, were showing a halo similar to oversharpening.  Reduced BrillColour from 8 to 1, well below the as-delivered setting of 6.  Also reduce Brightness from 1 to -3 to respond to comments about overall brightness: still able to see 1% step patterns near 3% and 97%.

UPDATE Mar 2018: Noted Reds were dull & biased towards brown. Adjusted R hue and sat a touch, and increased BrillColour and Sharpness.  We also now have a test image and reference print from Marrutt.  Settings as at Nov 2015 except as amended in colour…

This projector is a 4200 Lumen 1920 x 1080 pixel high definition projector.  It has a x1.5 zoom lens that facilitates quick image resizing so that we can use the full 6 foot wide screen for either 1920×1080 (16:9) or 1440×1080 (4:3) projection.

Aspect ratio & Zoom lens…

  • The native resolution is 1920 x 1080 pixels which is a Full HD 16:9 format.
  • If the projector is positioned with minimum zoom to fill our 6 foot screen, then the zoom can be increased until a 1440 x 1080 image also fills the screen.  Both Faststone and Dicentra detect the projector resolution and perform rescaling on the fly so can effectively project 1600 x 1200 images. [Note: 1440 & 1080 are exactly 90% of 1600 & 1200.]
  • The projector has been pre-loaded with a SCC test target so this, focussing and general alignment can all be completed before any video cables etc are attached.

Compatibility with Samsung laptop video chipset

  • The Samsung inbuilt display is (like the majority of medium cost laptops) limited to 1366 x 768 pixels so projecting the desktop simultaneously on both laptop and EH415e will not prove satisfactory.  There are two alternative options…
  • 1)  Only use the projector and disable the laptop display by using either “Windows key” + “P” or mouse right click on Desktop background to select Screen Resolution and choose Multiple Display = Show desktop only on 1.  The laptop should then drive the projector at its native 1920×1080 resolution.  Main disadvantage of this is that it is difficult to view the keyboard (e.g. scoring) in a darkened room.
  • 2) Use the dual display capabilities of the laptop video chipset by choosing Multiple Display = Extend these displays.  You can then check that laptop is “1” and the projector “2” using the Identify button: generally 2 is to the right of 1 but if this is inconvenient, you can drag and drop to swap the two screens over.  If a third screen appears, select it and then choose Remove this display from the drop-down list.
  • With dual displays, you can drag and drop programme windows using the conventional top bar of any window between the two screens.

Dicentra Dual screen facility

  • Recent updates to Dicentra have improved how it handles dual screen environments.  Version 4.6.107 now detects dual screen with two pop-ups asking for one to be dragged to the projector screen and one to be dragged to the laptop.  Note that some Dicentra pop-ups may appear on the projected image while others appear on the laptop.
  • When running a competition, it can be helpful to open an empty text document on the laptop display to provide some keyboard illumination.
  • As Dicentra has to be set up during the Competition Rules with the projected image size, unfortunately it is not then possible to properly preview or practice the competition on the laptop alone as about 12% is lost from both the top and bottom of the image – but you can at least check image order, titles etc.  As a work-around, there is an icon on the desktop PREVIEW DICENTRA COMPS that opens to give a shortcut to the internal Dicentra folders that with care can be  browsed as a slideshow.
  • For more details on dual screen and Dicentra, read an up-to-date User Manual (Chapter 10).

MAC HDMI Video Colour Spaces…     (added 11/1/16)

  • Our Windows PCs output RGB16-235 colour space for HDMI inputs as it recognises the projector as a monitor.
  • However, Macbooks apparently recognise any 1920×1080 HDMI device as a video product and accordingly default to a YCbCr colour space (the digital equivalent to YUV) which results in an unusable image.  Two options exist if this happens:-
  •    a) Use VGA cable
  •    b) Change the Colour Space on the projector under Menu/Image/Colour Space to either Auto or YUV

Dicentra Workflow for internal Competitions (E.g. Shuffell, PDI of the Year)
[Team (eg LvG) or Inter-Club Comps need a different workflow!]

NOTE! Dicentra has evolved a lot and now can handle rescaling on the fly so PDIs can be loaded into competitions at the 2019 standard of 1600×1200 pixels.

Status: 1st draft Dec 2015

SCC have been developing better ways to select images to represent our Club in external competitions.  The traditional method has been to appoint a small Selection Committee which rather isolates the rest of the club from both the selection process and the subsequent competition.  What we are now doing is to try to use the power of the internet to allow the whole membership to participate fully in the selection and to email us with their own personal votes.  These will then be processed by an automated spreadsheet to generate our list of print or PDI titles.  The first version of the spreadsheet allowed us to have up to 9 people selecting and we have stretched this to cater for up to 30 members.

The outline process is as follows:-

1) All candidate images (normally high-scoring ones from internal competitions during the previous 12 to 18 months) are numbered together with their scores, titles, and author, and these are stored in Dropbox.  An invitation containing a link to the Dropbox images is emailed to participating members.

2) The participating members then email the numbers of their selected images back to us.  We don’t need any order of preference, titles or anything else.  Just a list such as   6, 9, 14, 16, 17, 22, 38, 44, 45, 48 is perfect as we can enter these into our spreadsheet by copy and paste rather than having to retype.  (You can also ring us with your list if really necessary.)

It is important that members do not deliberately include or exclude their own or their partners images: all images should be fairly considered in the context of the competition and other candidate images.  Also be aware of the need not to exceed the maximum number of images from any one author.

3) The spreadsheet then computes the total votes and lists the images in descending order.  The adjudicator then checks the list (e.g. in case there are too many images from one author, or there are too many similar images) and makes any final adjustments before compiling the club’s official competition entry.

  If you wish to play with the spreadsheet (which is still being refined), you can download a copy by right clicking and saving this link… Multijudge Mk3_Blank_Oct14  .  It has been developed in Excel 2003 so should work on later versions.  As we use LibreOffice (the totally free alternative to MS Office) on the club laptop, we intend to create a version for this also.  The spreadsheet has three tabs at the bottom: one for entering votes, one for the results, and one with some notes and instructions.  Any comments are always welcome.
