Exposure

Activity 3.1: Exposure compensation

Light and shade:

It looks as though the +1 had the best result here. Because it’s a very bright scene, with direct sunlight and a white wall, some of the darker shades are lost without the exposure compensation.

 

Activity 3.2: Black, white and 18% grey

Light metering:

+2 exposure compensation produced the best result here. The details of the chair are more visible where as it’s lost in the lighter or darker images.

 

For the white scene, the best image was with +2 exposure compensation, the shadows are lightened but the detail remains visible.

A final interesting observation is that the images all looked far brighter on my cameras LCD screen than they do on my computer screen.

Focal Length Experiment

For this exercise, we had to use a zoom lens, to capture a portrait image (i.e. photograph of a person) at wide-angle, normal and telephoto focal lengths.

Things to note:

  • A lens of focal length 35 mm or less is considered wide-angle. 
  • The most common telephoto zoom lenses have a focal range of 70mm to 200mm.
  • A normal focal length is around 50mm

This means I had to use two cameras to get the shots.

The Fujifilm XT10 has an APS-C sized sensor with a 1.5x crop factor.  This means that:

  • 16mm lens (the longer of the two) is actually 24mm which I’ve used for the Wide Angle Shot.
  • 27mm lens pancake is actually 40mm so I’ve used this for the Normal Shot.

The Sony Cyber-shot DSC-HX200V has a sensor size is 1/2.3” (~ 6.16 x 4.62 mm) and  crop factor is 5.62 (https://www.digicamdb.com/specs/sony_cybershot-dsc-hx200v/) which means that the lens has a  Focal length (35mm equiv.): 27 – 810 mm.

  • For the Telephoto lens, I stood about 3 meters away and zoomed in to about two thirds so it was approx 260mm. (I’m still confused by crop factor so not really sure if this is correct).

This telephoto lens shot was the best shot by far. See below.

Shot 3 – Telephoto – approx 250mm

Shot 2 – Normal (Should be 50mm but didn’t have it so have used 40mm instead)

 

Wide angle (fuji 16-24mm)

Tomorrow I’m heading to the park on a sunny day so will take the equivalent photos on landscape and post them here.

A Colour Story

I set myself a somewhat challenging task, strolling through Berlin on a cloudy afternoon in search of pops of the colour yellow.

Luckily the sun made a brief appearance and I found a few interesting gelb subjects.

Here are the unedited images 👇🏼 and you can find a summary of what I’ve learned in module one of photo imaging at the end of the post.

Learnings from module one of Photo Imaging:

  • Photography History:
    • Many people credit Louis Jacques Mandé Daguerre with being the “father of photography.” While he may have been the first to make it practical with his Daguerreotypes, the first photograph was created by Joseph Nicéphore Niépce’s “View from the Window at Le Gras.” c. 1826
    • Julia Margaret Cameron was the first portrait photographer
  • Technical Stuff:
    • I learned how to use my new Fujifilm X-T10 and how to set program mode
    • I learned I may need a 56mm lens for portrait images
    • I now know how a camera operates internally and the difference between mirrorless and DSLR cameras
  • Camera Basics:
    • All about ISO, Shutter Speed and Aperture – how they work and which situations to utilise them in – still much to learn here 🙂
    • SLR stands for Single Lens Reflex camera
    • So much more!
