Photoblog

Photoblog is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Photoblog rather than just read about it. In short: A photoblog (or photolog) is a form of photo sharing and publishing in the format of a blog. It differs from a blog through the predominant use of and focus on photographs rather than text.

Key takeaways

Photoblog belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Photoblog to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Photoblog from memory before moving on to harder problems.

Reference excerpt

A photoblog (or photolog) is a form of photo sharing and publishing in the format of a blog. It differs from a blog through the predominant use of and focus on photographs rather than text. Photoblogging (the action of posting photos to a photoblog) gained momentum in the early 2000s with the advent of the moblog and cameraphones.

Construction There are three popular ways to host a photoblog. Photoblogs on individual domains, photoblogs on blogging hosting services such as WordPress or Blogger, and photoblogs on photo specific blogging services such as Fotolog or Flickr. The dynamic nature of blogs, including photoblogs compared to static sites means that blogs require some form of content management system (CMS) rather than being built mostly by hand. These content management systems usually provide the photoblog's authors with a web service that allows the creation and management of posts and the uploading of images. The CMS delivers webpages based on the data entered by the photoblog author. Access to photoblogs is usually unrestricted and available to anyone with internet access and a web browser. Some existing blogging CMS have been modified by the use of add-ons or plugins (and sometimes core code rewriting) to enable the transition from text blogging to photoblogging. As an example, a photoblog author might limit his blog to display a single entry per day (as opposed to several entries which is typical for text blogs) and he might put thumbnails in entry excerpts to provide archives that display images instead of text snippets. Over time, developers have begun to write purpose-built CMS just for creating photoblogs. Additionally, many services specializing in hosting and displaying images, such as Flickr and Fotolog, have APIs that allow other blogging systems to display their images, giving the user many options as to the construction of a particular site. Good photoblogging platforms also include camera metadata (Exif) that display the camera settings of each photo taken.

Developments and accessibility The early days of photoblogging required some level of technical experience with setting up a webserver and installing or writing the CMS code for it (e.g. Pixelpost or Picoplog). Some photobloggers still prefer this option of running their own server, as this gives them full control over the display and functionality of their photoblog. However, there are now a range of photoblog hosting services available which provide a ready-made solution in which everything has already been set up. This has made photoblogging more accessible to the layman. Convergence of mobile phones with digital cameras has opened a new era in photoblogging as authors may publish photos directly from smart devices to the Web. Visual blogging enables people with limited English, or low literacy to contribute to material on the Web. Combined with automatic (photo-booth) uploading technology, this is a powerful tool to build digital literacy and digital citizenship in marginalized groups.

Worked examples

Example 1 — a first encounter with Photoblog

Start with the simplest possible case. Write down what Photoblog claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Photoblog before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Photoblog ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Photoblog

In research: Photoblog appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Photoblog in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Photoblog is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2000s neologisms, Internet terminology, Photoblogs, so understanding it makes those chapters shorter.
In everyday life: Look for Photoblog outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Photoblog in simple terms?

A photoblog (or photolog) is a form of photo sharing and publishing in the format of a blog. It differs from a blog through the predominant use of and focus on photographs rather than text.

Why does Photoblog matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Photoblog?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
