Exposure. It’s essential to producing high-quality photographs, but mastering exposure is difficult. At last there’s a BetterPhoto guide to exposure, packed with BetterPhoto’s signature assignments, diagrams, tips, and illustrations. It’s like a full-scale photography course between the covers of the book–all taught the BetterPhoto way, just like photographers learn at the top photography-instruction site on the web. There’s plenty of information here on both digital and film photography, discussing how different file formats affect exposure, how to adjust digital files, color correction, combining digital exposures, and much more. The author’s stunning full-color photographs make this hardworking guide as inspiring as it is instructive.

In an alternate Britain, an immersive theatre like no other unravels a mystery from beyond the grave. Perfect for fans of Black Mirror. In a Britain akin to this one, Vincent Rice falls off a ladder, literally at Petra Orff’s feet. They introduce themselves, and immigrant Petra senses a kindred spirit in Vincent’s complex sense of home. He offers to take her to Metamuse, an alternative theatre experience like no other that he won tickets to in a competition he doesn’t remember entering. The first show leaves them besotted with each other; the second is far more disturbing. Inexplicable occurrences pile on top of one another, all connected to the mysterious Metamuse. Only Petra can see the web of sinister coincidences surrounding them both and, with injustices both past and present weighing on her mind, she begins to wonder if Metamuse is more than just a show…

This User’s Guide is a resource for investigators and stakeholders who develop and review observational comparative effectiveness research protocols. It explains how to (1) identify key considerations and best practices for research design; (2) build a protocol based on these standards and best practices; and (3) judge the adequacy and completeness of a protocol. Eleven chapters cover all aspects of research design, including: developing study objectives, defining and refining study questions, addressing the heterogeneity of treatment effect, characterizing exposure, selecting a comparator, defining and measuring outcomes, and identifying optimal data sources. Checklists of guidance and key considerations for protocols are provided at the end of each chapter. The User’s Guide was created by researchers affiliated with AHRQ’s Effective Health Care Program, particularly those who participated in AHRQ’s DEcIDE (Developing Evidence to Inform Decisions About Effectiveness) program. Chapters were subject to multiple internal and external independent reviews. More more information, please consult the Agency website: www.effectivehealthcare.ahrq.gov)
