5/3/2023 0 Comments Shooting raw and fotofuse![]() Here’s a snippet of a sidecar file that was created alongside one of my RAW files. ![]() The alternative is to convert the photo to a more compatible RAW format such as DNG or into a JPEG, thereby destructively baking in all edits made into a compressed, lossy file. When sharing a processed RAW photo, you need to provide both the RAW file and its respective sidecar file to preserve your edits. That is why editing RAW files are non-destructive Every editing step you take is stored in the sidecar file and never gets written to the RAW file. The associated "sidecar" file created alongside every edited RAW file stores changes made in applications like Adobe Lightroom and Capture One. This RAW file is never touched during the editing process, hence the term “non-destructive.”Ģ. Each camera manufacturer has its proprietary file format. The RAW file contains all the sensor data and camera metadata created when your camera completes an exposure. I recorded this video to provide a much clearer understanding of what it means to have access to a RAW file’s added dynamic range and color information.ĭid you know that each RAW file is greater than the sum of its parts? It's true! We generally refer to a RAW file as a singular item, but three components make up each one:ġ. However, it’s also important to see the material impact that a RAW file has during post-processing, especially when compared to a JPEG file. I’ll cover a lot of topics related to the benefits and differences of RAW and JPEG files in this article. Comparing RAW and JPEG editing workflows. But first, it’s worth defining both file formats. I will shed light on the benefits and limitations of RAW and compare it to the JPEG format because it has several merits worth considering. So, yes, most photographers would agree that it's essential to shoot RAW, but I suspect that far fewer of them understand the myriad reasons why it's beneficial. Now, I don't think twice about space limitations resulting from shooting RAW, especially considering that the cameras I use have two card slots, effectively doubling my total storage capacity. Thankfully, the price of removable media cards has dropped significantly while maximum capacity has rapidly increased over the years. ![]() Historically, photographers would have to think twice about selecting RAW because its larger file size would quickly fill up removable media cards. And while I filmed this video in 2016 using a now-dated Sony a7R II, the RAW settings I discuss are just as relevant today. You’ll see that I spend a good chunk of time explaining the RAW setting I use and why I prefer it. ![]() I even recorded this video walkthrough of how I set up a new camera. The typical default setting that camera manufacturers ship their cameras with is JPEG, and I'll explain why later on, so my first order of business is to change it to RAW. Without fail, the first one I change is the file format. After carefully inspecting the dials, buttons, and displays, I begin a systematic journey to examine each of its settings. I have a special ritual I follow whenever I buy a new camera. It's also important to understand the benefits and limitations of both RAW files and JPEG files, arguably the most used and compatible image file format available. You've probably been told that you must shoot in RAW if you want to get the best quality out of your photos, and while that statement is valid, you should also have a clear understanding of what makes it accurate. Of all these tidbits thrown at photographers, the file formats you use when taking digital photos are one of the most commonly discussed and are essential to understand. You likely hear or read words like uncompressed, lossy, and non-destructive and see statements extolling the importance of using the most optimal camera settings all the time. Understanding the difference between RAW and JPEG photosĪ growing list of terminology has made its way into today's digital photography zeitgeist.

5/3/2023 0 Comments Amazon redshift logoData ingestion into Redshift is performed by issuing a simple COPY command from Amazon S3 (Simple Storage Service), or DynamoDB. It takes just minutes to create a cluster from the AWS console. Redshift’s cloud-based solution helps enterprises overcome these issues. Second, after a few months or years, data size invariably tended to increase, meaning companies needed to choose between investing in new hardware or tolerating slow performance. This factor required firm budgetary and strategic commitment from leadership. First, on-premise warehouses are expensive and take months to get running. Traditionally, enterprises have encountered several challenges while setting up data warehouses. How Redshift scores over traditional data warehouses Over the past five years, Redshift has emerged as one of the leading cloud solutions through its unparallelled ability to provide organizations with business intelligence. The solution has quickly become an integral part of the big data analytics landscape through its ability to perform SQL-based queries on large databases containing a mix of structured, unstructured, and unstructured data. In 2012, Amazon invested in the data warehouse vendor, ParAccel (now acquired by Actian) and leveraged its parallel processing technology in Redshift. Redshift delivers incredibly fast performance using two key architectural elements: columnar data storage and massively parallel processing design. Based on PostgreSQL, the platform integrates with most third-party applications by applying its ODBC and JDBC drivers. What is AWS Redshift?ĪWS Redshift is a cloud-based petabyte-scale data warehouse service offered as one of Amazon’s ecosystem of data solutions. In this article, we explore the world of Redshift, its powerful features, and why so many companies are choosing Redshift for data storage and analytics. ![]() From unbeatable performance to unlimited scalability, the number of enterprise customers using Redshift is increasing by the day. ![]() One of Amazon’s flagship products, AWS Redshift’s cloud-based data warehouse service is an industry gamechanger. AWS Redshift is a major driver of that growth. It’s estimated that by 2020, Amazon Web Services (AWS) will register revenues of $44 billion, twice the combined revenue of its two key cloud competitors: Google Cloud and Microsoft Azure. Over the past 12 years, Amazon’s cloud ecosystem has experienced astounding growth.
