For action passing toward or away from the camera at approximately 45 degrees only 2/3 of the speed indicated is needed. Panning Panning: In panning, remember that you will be moving the camera along with the subject that is moving. Your subject will be sharp and your background will be blurred to emphasize the motion. Your model must move from left to right, not front to back. (perpendicular) Before taking the photo, pre-focus and properly set your exposure. Try using a shutter speed of 1/60 or slower Show Motion To blur motion use a slow shutter speed. The slower the shutter speed the more the action will look blurred in your photograph. Remember to hold the camera steady, because even breathing will cause blur in the photo so try not to move the camera or use a tripod. Use any shutter speed lower than 60. Stop Motion Capture the movement to “freeze” the action. There should be no blur. The faster the shutter speed, the sharper the motion will appear in the photo. Use a shutter speed of 250 or faster Motion Series Depth of Field Depth of Field refers to the zone of apparent sharpness. 3 Ways to Control Depth of Field: 1. The size of the lens opening A. the larger the aperture the shallower the depth of field B. f/2.8, f/1.7 AND f/4 have a short area of focus or a shallow depth of field 2. Distance controls the depth of field A. the farther the camera to subject distance, the greater the depth of field B. the closer the camera to subject distance, the shallower the depth 3. Focal Length controls the depth of field A. The longer the focal length of the lens, shallower the depth Depth of Field To adjust your shutter speed with the DSLR put your camera setting to A priority.

Completing a Photography Exhibit Data Tag Current Data Tags are available at: https://unl.box.com/s/1ttnemphrd4szykl5t9xm1ofiezi86js Camera Make & Model: Indicate the brand and model of the camera, such as Google Pixel 2, Nikon Coolpix B500, or Canon EOS Rebel T7. Focus Type: • Fixed Focus means the photographer is not able to adjust the focal point. These cameras tend to have a large depth of field. This might include basic disposable cameras. • Auto Focus means the camera automatically adjusts the optics in the lens to bring the subject into focus. The camera typically selects what to focus on. However, the photographer may also be able to select the focal point using a touch screen for example, but the camera will automatically adjust the lens. This might include digital cameras and mobile device cameras, such as phones and tablets. • Manual Focus allows the photographer to manually adjust and control the lens’ focus by hand, usually by turning the focus ring. Camera Type: Indicate whether the camera is digital or film. (The following Questions are for Unit 2 and 3 exhibitors only.) Did you manually adjust the aperture, shutter speed, or ISO? Indicate whether you adjusted these settings to capture the photo. Note: Regardless of whether or not you adjusted these settings manually, you must still identify the images specific F Stop, Shutter Sped, ISO, and Focal Length settings. “Auto” is not an acceptable answer. Digital cameras automatically record this information for each photo captured. This information, referred to as Metadata, is attached to the image file and goes with it when the image is downloaded to a computer for example.

Depth-Aware Blending of Smoothed Images for Bokeh Effect Generation
1 Depth-aware Blending of Smoothed Images for Bokeh Effect Generation Saikat Duttaa,∗∗ aIndian Institute of Technology Madras, Chennai, PIN-600036, India ABSTRACT Bokeh effect is used in photography to capture images where the closer objects look sharp and every- thing else stays out-of-focus. Bokeh photos are generally captured using Single Lens Reflex cameras using shallow depth-of-field. Most of the modern smartphones can take bokeh images by leveraging dual rear cameras or a good auto-focus hardware. However, for smartphones with single-rear camera without a good auto-focus hardware, we have to rely on software to generate bokeh images. This kind of system is also useful to generate bokeh effect in already captured images. In this paper, an end-to-end deep learning framework is proposed to generate high-quality bokeh effect from images. The original image and different versions of smoothed images are blended to generate Bokeh effect with the help of a monocular depth estimation network. The proposed approach is compared against a saliency detection based baseline and a number of approaches proposed in AIM 2019 Challenge on Bokeh Effect Synthesis. Extensive experiments are shown in order to understand different parts of the proposed algorithm. The network is lightweight and can process an HD image in 0.03 seconds. This approach ranked second in AIM 2019 Bokeh effect challenge-Perceptual Track. 1. Introduction tant problem in Computer Vision and has gained attention re- cently.

DEPTH of FIELD CHEAT SHEET What Is Depth of Field? the Depth of Field (DOF) Is the Area of a Scene That Appears Sharp in the Image
Ms. Brown Photography One DEPTH OF FIELD CHEAT SHEET What is Depth of Field? The depth of field (DOF) is the area of a scene that appears sharp in the image. DOF refers to the zone of focus in a photograph or the distance between the closest and furthest parts of the picture that are reasonably sharp. Depth of field is determined by three main attributes: 1) The APERTURE (size of the opening) 2) The SHUTTER SPEED (time of the exposure) 3) DISTANCE from the subject being photographed 4) SHALLOW and GREAT Depth of Field Explained Shallow Depth of Field: In shallow depth of field, the main subject is emphasized by making all other elements out of focus. (Foreground or background is purposely blurry) Aperture: The larger the aperture, the shallower the depth of field. Distance: The closer you are to the subject matter, the shallower the depth of field. ***You cannot achieve shallow depth of field with excessive bright light. This means no bright sunlight pictures for shallow depth of field because you can’t open the aperture wide enough in bright light.*** SHALLOW DOF STEPS: 1. Set your camera to a small f/stop number such as f/2-f/5.6. 2. GET CLOSE to your subject (between 2-5 feet away). 3. Don’t put the subject too close to its background; the farther away the subject is from its background the better. 4. Set your camera for the correct exposure by adjusting only the shutter speed (aperture is already set). 5. Find the best composition, focus the lens of your camera and take your picture.

Minoru Photo Club the Art of Panning (By Natalie Norton ) What Is
Minoru Photo Club July 24, 2018 There are different ways of creating a sense of movement in photography. From John Hedgecoe’s Photography Basics, he listed four ways – Slow Shutter, panning, diagonal movement and zoom movement. For today, I will share with you what I have researched on the art of panning using a slow shutter speed. There are many unwritten rules in photography. Keeping your camera steady is one of them. Well, for this artistic technique, you will need to forget all you have learned about the importance of shooting with a rock-solid camera. The creative result will be many cool motion-blur images The Art Of Panning (by Natalie Norton) What is Panning? Panning is one of many artistic techniques for more creative photographs. It is the horizontal movement of a camera, deliberately moving or panning the camera, as it scans a moving subject. It is the swinging of the camera - steadily to follow a passing subject, (can keep a moving image in one place on the film). Panning is another effective way of instilling a sense of motion in a picture with a moving subject. The result is a fairly sharp subject set against a blurred and streaked background. This gives the shot a real feeling of motion, speed and action. SOME TIPS & GUIDELINES: Subject/What should I Photograph? – since you want to create a sense of motion, your obvious subject choices include cars, racing cars, joggers, cyclists, etc.. But do try this technique when capturing pets, horses, people running or even someone on a swing.

Dof 4.0 – a Depth of Field Calculator
DoF 4.0 – A Depth of Field Calculator Last updated: 8-Mar-2021 Introduction When you focus a camera lens at some distance and take a photograph, the further subjects are from the focus point, the blurrier they look. Depth of field is the range of subject distances that are acceptably sharp. It varies with aperture and focal length, distance at which the lens is focused, and the circle of confusion – a measure of how much blurring is acceptable in a sharp image. The tricky part is defining what acceptable means. Sharpness is not an inherent quality as it depends heavily on the magnification at which an image is viewed. When viewed from the same distance, a smaller version of the same image will look sharper than a larger one. Similarly, an image that looks sharp as a 4x6" print may look decidedly less so at 16x20". All other things being equal, the range of in-focus distances increases with shorter lens focal lengths, smaller apertures, the farther away you focus, and the larger the circle of confusion. Conversely, longer lenses, wider apertures, closer focus, and a smaller circle of confusion make for a narrower depth of field. Sometimes focus blur is undesirable, and sometimes it’s an intentional creative choice. Either way, you need to understand depth of field to achieve predictable results. What is DoF? DoF is an advanced depth of field calculator available for both Windows and Android. What DoF Does Even if your camera has a depth of field preview button, the viewfinder image is just too small to judge critical sharpness.

In contrast, the real field of view is the range on the workpiece surface when actually magnified and observed with the objective lens.

Special Techniques to Make Your Image Different
Special techniques to make your image different 1. Timelapse in one image During a photo tour in Yunnan province, China, we go shoot at a busy local market. I, however, like to experiment something new, presenting the hustle and bustle of the market photographically in a unique way: A time-lapse compressed into one image. To achieve the result, 2 approaches coming to my mind: Option 1. Using the in-camera Multiple exposure mode: Nikon cameras has multiple exposure functions for long time. After years of being ignored, it finally comes to Canon cameras starting 5D III, which I happen to use. This one is shot using "Average" mode in multiple exposure, I set total of 9 exposures, taking one shot every couple seconds, the exposure is automatically reduced, proportional to the number of shots taken, to avoid over-exposing common areas or overlapping bright areas. Where overlapping areas do occur, the final brightness level will be the same as the would have been in a single, properly- exposed shot. And, any non-overlapping areas will be darkened. The final combined image is automatically generated by the camera. The pro is that you can experiment a lot with this technique, simple and fast. The con however, is that you have no control on the resulting image at all. The camera has full control here. Option 2. Taking a lot shots and manipulate them in post processing: This is a hard way, but you have absolute control of the final image. It, however, is time-consuming and requires lots of fiddling with Photoshop.

Depth of Field in Photography
Instructor: N. David King Page 1 DEPTH OF FIELD IN PHOTOGRAPHY Handout for Photography Students N. David King, Instructor WWWHAT IS DDDEPTH OF FFFIELD ??? Photographers generally have to deal with one of two main optical issues for any given photograph: Motion (relative to the film plane) and Depth of Field. This handout is about Depth of Field. But what is it? Depth of Field is a major compositional tool used by photographers to direct attention to specific areas of a print or, at the other extreme, to allow the viewer’s eye to travel in focus over the entire print’s surface, as it appears to do in reality. Here are two example images. Depth of Field Examples Shallow Depth of Field Deep Depth of Field using wide aperture using small aperture and close focal distance and greater focal distance Depth of Field in PhotogPhotography:raphy: Student Handout © N. DavDavidid King 2004, Rev 2010 Instructor: N. David King Page 2 SSSURPRISE !!! The first image (the garden flowers on the left) was shot IIITTT’’’S AAALL AN ILLUSION with a wide aperture and is focused on the flower closest to the viewer. The second image (on the right) was shot with a smaller aperture and is focused on a yellow flower near the rear of that group of flowers. Though it looks as if we are really increasing the area that is in focus from the first image to the second, that apparent increase is actually an optical illusion. In the second image there is still only one plane where the lens is critically focused.

Depth of Field and Depth of Focus Explained
1 Reference: Queries. Vol. 31 /1 Proceedings RMS March 1996 pp64-66 Depth of Field and depth of Focus Explained What is the difference between 'depth of field' and 'depth of focus'? - I have seen both terms used in textbooks This is a good question, which prompts an answer that encompasses more than simply terminology. In the past there has been some confusion about these terms, and they have been used rather indiscriminately. Recently, usage has become more consistent, and when we published the RMS Dictionary of light Microscopy in 1989, we felt able to make an unambiguous distinction in our somewhat ponderous definitions: • Depth of field is the axial depth of the space on both sides of the object plane within which the object can be moved without detectable loss of sharpness in the image, and within which features of the object appear acceptably sharp in the image while the position of the image plane is maintained. • Depth of focus is the axial depth of the space on both sides of the image plane within which the image appears acceptably sharp while the positions of the object plane and of the objective are maintained. The essential distinction between the terms is clear: depth of field refers to object space and depth of focus to image space. A possibly useful mnemonic is that the field of view is that part of the object that is being examined, and the focus is the point at which parallel rays converge after passing through a lens. These definitions contain two rather imprecise terms: detectable loss of sharpness, and acceptably sharp; clearly it all depends on what can be detected and what is considered acceptable.

Visual homing with a pan-tilt based stereo camera Paramesh Nirmal and Damian M. Lyons Department of Computer Science, Fordham University, Bronx, NY 10458 ABSTRACT Visual homing is a navigation method based on comparing a stored image of the goal location and the current image (current view) to determine how to navigate to the goal location. It is theorized that insects, such as ants and bees, employ visual homing methods to return to their nest [1]. Visual homing has been applied to autonomous robot platforms using two main approaches: holistic and feature-based. Both methods aim at determining distance and direction to the goal location. Navigational algorithms using Scale Invariant Feature Transforms (SIFT) have gained great popularity in the recent years due to the robustness of the feature operator. Churchill and Vardy [2] have developed a visual homing method using scale change information (Homing in Scale Space, HiSS) from SIFT.
