Thumbnails and Contact sheets

Thumbnails – reduced size versions of photographs which makes organising and locating specific images easier.

Contact sheet – serve the same purpose as thumbnails.

Sometimes the two terms are often interchanged. I found that the term thumbnails is used more frequently and is related to all things computer based, but contact sheets are primarily photographic terms and can be created in a darkroom with film or digitally within photographic software.

Once I had the terms worked out the rest was easy to learn. I decided the final selected six photographs that were to be uploaded would be presented in a WordPress gallery block and I would manipulate the settings so that they were uniformed in size on the post. The downside of this was the photographs would be cropped to fit in with the ‘one size only’ look. However they do look like a contact sheet at a glance.

I next created ‘ contact sheet’ pages on my blog so that the course photographs can be uploaded onto them once they had been collated and made into contact sheets within Photoshop. This way I can link specific posts with contact sheets and show all my course photographic work.

This is my way of making the contact sheets using photoshop.

Exposure and all that jazz…. ISO, SS, F-stop and the exposure triangle.

Save JPEG > maximum/ optimum image quality. JPEG uses file compression that results in a loss in quality.

Image size Image files are usually large and it is best to keep them large to retain the maximum resolution for printing and archival purposes. But when you want to cross them over the internet to your tutor, you’ll need to make them a lot smaller…

… reducing the resolution will cause images to look less sharp and more pixelated… (OCA Foundations in photoshop course work folder pg29)

Depth of Field

  • Shallow depth of field = Most common use for a sharp focus on an object eg. portrait and a blurry background. Therefore separating subject from background. Use a long focal length on the lens and/or a wide aperture for eg. F2.8
  • Deep depth of field = Landscape – wide angle end of. zoom lens and an aperture of F8 will give a sharp near to far in distance from the camera.
  • Close-up depth of field = A very shallow depth of field eg. 1mm or 2mm at the most. Small aperture like f8

Flower photography: While I was getting ready to take photographs of flowers in the garden I read an article in a miscellaneous photography book about garden photography. I have jotted a few notes down that I found interesting and worth noting for future use.

  • overcast conditions are best – soft, even light.
  • strong sunlight -highlights and deep shadows.
  • light delicate flowers/ leaves from behind to see their structure and colour.
  • small aperture and lots of depth of field – detail.
  • large aperture – evocative and romantic.
  • spray water on flowers to give glistening rain feel/ texture.
  • if it is harsh light – use a diffuser such as a white umbrella to soften the light. An umbrella is good as it has a convenient handle for you to hold. Put a reflector/ white card/ scrunched up and then flattened out again tin foil, to bounce a bit of the light back into the shadows.

Depth of field

There is an excellent information source on the website, about depth of field.

Depth of field = the ability to decide which areas of your photograph is sharp. Our eyes keep everything in focus from our feet to infinity but we can manipulate our camera settings to decide which areas are in focus or not.

This technique enables us to create emphasis where we want it and to hide elements that may be distracting to our shot.

Tip: Juxtapositions

Photographers often use near/far, left/right. top/bottom compositions to set up a juxtaposition between different subjects in the frame….

Two subjects whose relationship is emphasised within the frame resonate against each other, both as relative points and conceptually. much staged photography is about setting up precisely these juxtapositions between objects to tell a story or give impression.

OCA Foundations in Photography course folder pg78

This article on the website expert gives 27 juxtaposition photography examples. It also states: ‘The definition of juxtaposition is placing two things together in order to show a contrast. In photography we use composition, clever use of forced perspectives or carefully placed props to convey the contrasts in the image. Photographs can also rely on cultural ideas and identities of the viewers.’

The 27 examples are:

  • Animate ‘v’ Inanimate
  • Big ‘v’ Small
  • Black ‘v’ White
  • Fat ‘v’ Skinny
  • Emotion ‘v’ Emotionless
  • Healthy ‘v’ Harmful
  • Human ‘v’ Machine
  • Lines ‘v’ Circles
  • Mixed Concepts Juxtaposition Examples
  • Nature ‘v’ Man-Made
  • New Technology ‘v’ Old Technology
  • New ‘v’ Old Architecture
  • Young ‘v’ Old People
  • Patterns and Colours Juxtaposition Examples
  • People ‘v’ Warfare
  • People ‘v’ Perception
  • Wealth ‘v’ Poverty
  • Poverty ‘v’ Idealism
  • Repurposing Juxtaposition Examples
  • Role Replacement Juxtaposition
  • Straight ‘v’ Curved
  • Power ‘v’ Weakness
  • Vintage ‘v’ Modern
  • Past ‘v’ Present
  • Expected ‘v’ Real Size
  • Stereotypes Juxtaposition

For every example in the list below the website has a photograph so that you can visually see the juxtaposition.

Well worth a visit, I learnt quite a lot!
