What is Bokeh in Photography

Bokeh is an aesthetic quality of the blur, in out-of-focus areas of an image. The Bokeh is either “good” or “bad” based on, if the blur is pleasant to eye or if it is unpleasant. Bokeh only occurs for the part of the image, which lies outside the depth of field.

The differences in lens aberrations and aperture shapes cause difference lens designs. This results in different kinds of bokeh.Image result for What is Bokeh in Photography

The term Bokeh sees its origin from the Japanese word boke, which means “blur” or “haze”.

Photographers use shallow focus techniques to create images with prominent out-of-focus regions. When used in Portrait photography, the photographer usually wants a shallow depth of field, so that the subject stands out sharply against a blurred background.

Some points about Bokeh:

Image result for What is Bokeh in Photography

Bokeh has several components, including edge effects around out-of-focus highlights and false edges in the rendering of out-of-focus details.

Bokeh rendering is not the same in all situations, and some lenses will be better than others in some situations. Lens bokeh is not a single value, and each lens requires considerable experience to understand where it is good and where it is not. Wider apertures do not necessarily improve bokeh.Image result for What is Bokeh in Photography

Specular highlights and other out-of-focus bright spots don’t tell the whole bokeh story.Longer focal lengths improve bokeh.

Lens complexity seems to have little bearing on bokeh. Lens design, however, is paramount.Aperture shapes are not really an issue with bokeh, especially near wide open.Image result for What is Bokeh in Photography

In last couple of decades, lens design has enjoyed a couple of breakthroughs. One is computer optimization, using the modulation  transfer function instead of ray-tracing. MTF provides a measure not only of acutance and resolution, but also how they interact with contrast to accurately represent fine detail in the photograph. The other breakthrough is low-dispersion and high-refractive glass. These two breakthroughs, coupled with advanced multi-coatings, have made complex designs possible, especially in with zoom lens.

OSFI Releases Cyber Security Self-Assessment Guidance

OSFI released its Cyber Security Self-Assessment Guidance (the “Guidance”) to aid Federally Regulated Financial Institutions (“FRFI”) in assessing its level of preparedness against cyber risks. The Guidance was drafted in response to OSFI’s Plans and Priorities for 2013-2016, a plan that emphasizes vigilance against the increasing frequency and sophistication of cyber threats.

Cyber Security Self-Assessment Template

The Guidance directs FRFIs to conduct self-assessments against a number of criteria in the following six categories:

Organizational Resources.e.g. Whether the FRFI has assigned specific roles and responsibility for the management of cyber security.

Cyber Risk and Control Assessment.e.g.  Whether the FRFI assesses and takes steps to mitigate potential cyber risk arising from its outsourcing arrangements deemed material under OSFI’s Guidelines B-10.Image result for OSFI Releases Cyber Security Self-Assessment Guidance

Situational Awareness.e.g. Whether the FRFI maintains current enterprise-wide knowledge base of its users, devices, applications, and their relationships.

Threat and Vulnerability Risk Assessment.e.g. Whether the FRFI has implemented tools to prevent unauthorized data leaving the enterprise.

Cyber Security Incident Management.e.g. Whether the FRFI’s change management process has been designed to allow for rapid response and mitigation to material cyber security incidents.

Image result for OSFI Releases Cyber Security Self-Assessment Guidance

Cyber Security Governance.e.g. Whether a Senior Management committee has been established that is dedicated to the issue of cyber risk.

Interestingly, unlike the recently released U.S. NIST Preliminary Cybersecurity Framework, the Guidance is broad and does not reference external standards (e.g. ISO Standards). As a consequence, there is a large degree of subjectivity involved in the self-assessment. While OSFI has stated that they do not have current plans to establish a more specific guidance, OSFI also confirmed that they may request FRFIs to complete this template during future supervisory assessments.
