Intro. to Digital Photography Study Guide TEST on Wednesday, Oct. 22nd Intro. to Digital Photography Study Guide 1. L.C.D. –Liquid Crystal Display screen 2. All images captured by a digital camera become __electronic___ documents. 3. Why is digital photography more environmentally friendly than traditional photography is? Because no chemicals are used to create pictures, there is no need to dispose of harmful substances. 4. What does an "image sensor" do? It captures and stores pictures. 5. What is the camera's "shutter speed"? the length of time the shutter of the camera is open and allows light to strike the image sensor 6. The word, "pixels," is short for "__picture elements____." 7. What are "pixels"? millions of tiny squares that compose the image 8. How does this differ from traditional photography (film)? Because film has small dots that make up an image, known as grain. 9. Digital camera resolution quality is often measured how? megapixels 10. Mega pixels is how many pixels? A million 11. Higher the megapixels the better off you are. 12. What is "resolution"? the number of pixels contained in a photographic image. 13. To get a closer frame cropping, what feature on your camera should you use? Zoom-in 14. High resolution pictures take up an enormous amount of __memory space____. 15. High resolution pictures are sharper than low resolution pictures. 16. Enlarging an image to five times the original size will cause image quality to ____degrade__ . 17. When you "crop" a picture, what do you do? You cut out parts of the image that you do not want to include in the picture. 18. What is recycle or lag time? The amount of time it takes the camera to process and store an image when shooting in normal mode. 19. Pressing the shutter button halfway does what? Auto focuses 20. Macro mode icon is a _tulip___ . (at right) 21. How does Macro work? Put function on macro then just get close to your subject. 22. Small Resolution “S” 640 x 480 Pixels is great for GREAT for websites because it is a monitor resolution. 23. Large Resolution “L” 4000 x 3000 Pixels is capable of huge prints and cropped, photo-quality 8” x 10”s from a fraction of the original image file. 24. Resolution differences in size: small 640 x 480, medium (can range) 1078 x 760, and large 2048 x1576. 25. Continuous Shooting Mode/Rapid Fire/Burst Mode- This feature allows you to take multiple rapid-fire shots with one touch of the exposure button. This can be very useful feature when shooting subjects in motion, such as during a sporting event. The icon looks like multiple rectangles. 26. JPEGs (.jpg) – Most common digital camera image format used for images with continuous tone changes such as photos. (* This is the one we will be using) 27. PSDs (.psd)- a photoshop native document, Saves all the layers so you can return and work back on the layered file. 28. PDF (.pdf)-stands for Adobe Acrobat’s Portable Document Format, a system for creating documents that can be read cross-platform. 29. Cross-platform means can be used on both MAC and PC computers. 30. CCD Raw (.raw) – An uncompressed image format that contains all of the data picked up by the image sensor. Professional Photographers use this one. 31. File Management: You should NEVER label your images by date OR leave them as IMG_001, IMG_002, etc. 32. Label your finished project: ALWAYS with your last name then project name. 33. In order to transfer images from camera to computer what mode does the camera have to be on? Camera MUST be “on” and in “preview” mode. 34. The Rule of Thirds is a principle of composition used for centuries by painters, photographers and other artists. The main subject is placed off center, away from the middle of the frame. As a result, photos often look more dynamic and interesting 35. Three major elements in a photograph: 1 - Foreground , 2 - Middle-ground , and 3 – Background. 36. Know what a photo using the Rule-of-Thirds would look like. 37. Be able to identify a photos Foreground, Middle-ground, and Background 38. Which tool in Photoshop would you use for what: Mover tool-Only good to move your image Eye dropper tool-get a sample of a color Marquee tool-To make a selection Quick Selection tool-Use when you have multiple colors but have a border. Magic Wand tool-Selects any solid colors easily (also know the Photoshop tools that WE HAVE USED SO FAR…below… .

  • Real-Time Burst Photo Selection Using a Light-Head Adversarial Network
    Real-time Burst Photo Selection Using a Light-Head Adversarial Network Baoyuan Wang, Noranart Vesdapunt, Utkarsh Sinha, Lei Zhang Microsoft Research Abstract. We present an automatic moment capture system that runs in real-time on mobile cameras. The system is designed to run in the viewfinder mode and capture a burst sequence of frames before and after the shutter is pressed. For each frame, the system predicts in real-time a \goodness" score, based on which the best moment in the burst can be selected immediately after the shutter is released, without any user interference. To solve the problem, we develop a highly efficient deep neural network ranking model, which implicitly learns a \latent relative attribute" space to capture subtle visual differences within a sequence of burst images. Then the overall goodness is computed as a linear aggre- gation of the goodnesses of all the latent attributes. The latent relative attributes and the aggregation function can be seamlessly integrated in one fully convolutional network and trained in an end-to-end fashion. To obtain a compact model which can run on mobile devices in real-time, we have explored and evaluated a wide range of network design choices, tak- ing into account the constraints of model size, computational cost, and accuracy. Extensive studies show that the best frame predicted by our model hit users' top-1 (out of 11 on average) choice for 64:1% cases and top-3 choices for 86:2% cases. Moreover, the model(only 0.47M Bytes) can run in real time on mobile devices, e.g.

  • An Analysis and Implementation of the HDR+ Burst Denoising Method
    Published in Image Processing On Line on 2021–05–25. Submitted on 2021–03–01, accepted on 2021–05–05. ISSN 2105–1232 c 2021 IPOL & the authors CC–BY–NC–SA This article is available online with supplementary materials, software, datasets and online demo at https://doi.org/10.5201/ipol.2021.336 2015/06/16 v0.5.1 IPOL article class An Analysis and Implementation of the HDR+ Burst Denoising Method Antoine Monod1,2, Julie Delon1, Thomas Veit2 1 MAP5, Universit´ede Paris, France ({antoine.monod, julie.delon}@u-paris.fr) 2 GoPro Technology, France ([email protected]) Abstract HDR+ is an image processing pipeline presented by Google in 2016. At its core lies a denoising algorithm that uses a burst of raw images to produce a single higher quality image. Since it is designed as a versatile solution for smartphone cameras, it does not necessarily aim for the maximization of standard denoising metrics, but rather for the production of natural, visually pleasing images. In this article, we specifically discuss and analyze the HDR+ burst denoising algorithm architecture and the impact of its various parameters. With this publication, we provide an open source Python implementation of the algorithm, along with an interactive demo. Source Code The Python implementation of HDR+ has been peer-reviewed and accepted by IPOL. The source code, its documentation, and the online demo are available from the web page of this article1. Compilation and usage instructions are included in the README.txt file of the archive. The code is also available on GitHub2. Keywords: burst denoising; computational photography; motion estimation; temporal filter- ing; high dynamic range; image signal processor 1 Introduction Image noise is a common issue in digital photography, and that issue is even more prominent in smaller sensors used in devices like smartphones or action cameras.
