What is the focus tool?
View Resource The FOCUS Tool is an online social and behavior change /communication strategy planner. FOCUS provides step-by-step guidance on how to develop or retrofit a theory-based social and behavior change/ communication (SBC/C) strategy. The steps, theoretical framework, and tools are designed to help SBC practitioners prepare and plan for effective SBC/C initiatives through a comprehensive approach.
- The final product is a draft narrative strategy that has been systematically developed and that can be further refined.
- The FOCUS tool was developed by Save the Children’s Saving Newborn Lives project and was demonstrated to Save the Children field staff in 2016, which gave the tool positive reviews for its ease of use, technical soundness, and practical applications.
Save the Children’s SBC experts have thoroughly reviewed the tool and are enthusiastic about its disruptive potential. Many program managers and health practitioners oversimplify social and behavior change (SBC), assuming it is about delivering messages to target audiences with pre-identified information and a list of desired behaviors – along with the naïve expectation that behavior change will result. 
The SBC theory and evidence base is much more dynamic than this, incorporating insights from sociology, psychology, behavioral science, cognitive neuroscience, and behavioral economics. The FOCUS tool provides a way to integrate these insights into a strategy-development toolkit, with the additional benefit of helping keep practitioners current.
Social and Behavior Change (SBC) refers to interventions that aim to change care seeking behaviors and the social norms and other community and environmental factors that enable or prevent them. SBC is understood to encompass a broad number of different disciplines, including (SBC/C), marketing, advocacy, behavioral economics, anthropology and human-centered design, social capital and social psychology.
“SBC is an essential element of global health programming, as it shapes not only demand for services, but also client-provider communication, couples’ communication, and the engagement of community leaders and other influencers.” (Definition adapted from HIP SBCC Brief, USAID 2018).
How do I make a selection sharper in Photoshop?
1. Unsharp Mask – Zoom in to 100%. Go to Filter > Sharpen and select ‘Unsharp Mask’ filter. The Unsharp Mask window will appear. Make sure to select the Preview option and that you can see the different areas of the image that you want sharper. You can see the effect of sharpening both in the little preview thumbnail and on the photo in your working area. 
The Amount slider sets the amount of sharpening. Usually, any digital photo file needs around 60% of sharpening for screen viewing. If you want to make large prints, you can go anywhere from 100 to 200. The Radius determines the number of pixels surrounding the edges that affect the sharpening. 
When sharpening for print, it can take some trial and error before you know the right settings. It depends on a variety of factors such as your camera type, sensor size, or print size.
How do you get selective focus?
Conclusion – Selective focus highlights part of your image by contrasting a subject sharply in focus with blurred elements. To create selective focus, choose a point of focus and set your camera to a wide aperture. Create a shallow depth of field in your image by using a wide aperture.
Many kit lenses have f/3.5 or f/4.0 as the widest apertures. Other speciality lenses may have apertures as wide as f/1.2. In general, the wider the aperture, the more blur. You may not need to set your camera at its widest aperture. If you want detail in the blurred parts of your image, choose a narrower f-stop like f/5.6 or f/11.
You can use depth of field calculators to help you determine where to position yourself relative to the subject, what aperture and focal length to use. Or you can take a more experimental approach. Try different apertures and move position around the subject.
How do you select perfectly in Photoshop?
Photoshop selection tools basics Learn how to create a selection, work with popular selection tools, and fine-tune the edges of a selection in Adobe Photoshop. Use a selection to edit part of an image. What you learned: To make a selection and adjust only the selected area A selection isolates part of an image so you can work on that area without affecting the rest of the image.
In the Tools panel, select the Rectangular Marquee tool. Drag a rectangular selection onto the image. The area inside the animated border represents your selection. To select more, click the Add to selection icon in the options bar or press Shift and drag. To select less, click the Subtract from selection icon in the options bar or press Alt (Windows) or Option (macOS) and drag. Select a layer you want to adjust. Then try applying some adjustments ( Image > Adjustments ). With a selection active, adjustments affect only the selected area of that layer. The same is true if you were to apply a filter, paint, fill, copy, or make other edits. When you’re done, deselect by choosing Select > Deselect or pressing Control+D (Windows) or Command+D (macOS).
What you learned: Use the Quick Selection tool
In the Tools panel, select the Quick Selection tool. Drag over an area you want to select. This tool tries to find image edges and automatically stops the selection there. After your initial selection, this tool automatically switches to its Add to Selection option. To select more, drag over other areas. To select less, hold the Alt key (Windows) or the Option key (macOS) as you drag over areas to remove from the selection. Experiment with adjusting the size and hardness of the Quick Selection tool in the options bar.
Use the Lasso tool
In the Tools panel, select the Lasso tool. This tool is useful for cleaning up a selection that you started with another tool. To add to a selection made with any tool press Shift and drag around the area you want to add. To subtract from a selection, select the Subtract from selection option in the options bar or press Alt (Windows) or Option (macOS) and drag around the area you want to remove. Press Control+D (Windows) or Command+D (macOS) to deselect.
To fine-tune a selection in the Select and Mask workspace What you learned: To enhance a selection
Make a selection with a selection tool, like the Quick Selection tool. In the options bar, click Select and Mask to open the Select and Mask workspace. Go to the View menu on the right side of the workspace and choose one of the view options, like Overlay, for a more accurate view of your selection. In Overlay view, the selected area is clear and the non-selected area is translucent red by default. In the Tools panel, select the Brush tool. Paint on the image where you want to add to the selected area. If you want to subtract from the selected area press Alt (Windows) or Option (macOS) and paint on the area to remove. Scroll down on the right side of the workspace to the Output Settings > Output to menu, and choose Selection as the output type. Click OK to close the Select and Mask workspace.

Finding It Hard to Focus on Objects at Close Distances? You May Have Presbyopia Published on May 31, 2019 by Hitesh Patel Presbyopia is a condition characterized by the inability to focus on objects that are close to you.

Most people tend to develop the condition beyond the age of 40. People who have it often experience problems reading small print. Presbyopia will affect most people and is virtually inescapable. Even those who have never had vision problems may acquire this condition at some point in their lives. Even people who already suffer from nearsightedness will end up with presbyopia, which manifests itself in the form of an increase in their already-existing condition.
What’s worse, it cannot be corrected using their current eyeglasses or contact lenses. By 2020, there will be approximately 2.11 billion people with presbyopia. Now, presbyopia may be a normal condition that appears with age, but it can still be very frustrating.
