This program has been created by a professional landscape photographer for other photographers. It can calculate HDR exposure difference, noise reduction, and multi-pass up sampling, common techniques used by the pros to produce professional-caliber photographs.
High Dynamic Range (HDR) Photography is becoming increasingly popular. Exposure bracketing, a technique frequently employed by the HDR Photographer, involves varying the shutter speed (and less commonly, aperture and ISO) in successive exposures of the same scene. This program is especially useful because it calculates the difference in exposure values (E.V. or stops) between two such captures, even if the ISO, aperture, and shutter speeds wildly differ between exposures. This value may then be utilized to either verify or supplant that calculated by HDR programs such as Photomatix or HDR Efex Pro at the start of the HDR workflow.

But that’s not all this program does. It can also calculate how much you need to resize (downsample) a particular image to drastically reduce the amount of random photographic noise by a specified number of stops. All you need to do is specify the desired number of stops of noise reduction, and the program calculates the resized image’s linear dimensions (length/width) as a percentage of the original image’s.
To those of you who routinely upsample your images (perhaps to display in a gallery or on a billboard), the Multi-Pass Upsampling calculator of program will prove especially useful. It can calculate the number of passes necessary to enlarge an image in small, arbitrary, user-specified increments until the final enlarged size is attained. Upsizing an image in multiple, iterative steps rather than a single one yields higher micro-contrast and greater detail than would be accomplished through more traditional means such as single-pass bicubic upsampling. In fact, the results of this technique are almost on par with those achieved by resizing using fractal resizing.

Joanne Carter is a British photography journalist, editor, curator, and the founder of *TheAppWhisperer.com*, one of the world’s leading platforms dedicated to mobile photography and art. Since its launch in 2009, TheAppWhisperer has become an international hub for artists of all levels to discover, learn, exhibit, and engage with contemporary photographic practice.Built on principles of inclusivity, accessibility, and artistic excellence, Joanne has spent almost two decades championing mobile photography as a serious artistic medium. Through interviews, critical essays, exhibitions, competitions, and education, she has helped shape and document the evolution of mobile art on a global scale.Her work has taken her internationally, lecturing on photography and mobile art at institutions and events including the Museum of Art in Seoul, South Korea, alongside appearances in the UK and Europe. She has served as a juror for international photography and mobile art awards across Portugal, Canada, the United States, South Korea, Italy, and the UK.Joanne is also the founder of *TheAppWhispererPrintSales.com*, one of the first online galleries dedicated exclusively to collectible mobile art, connecting artists with collectors across Europe, the United States, and Asia.Before founding TheAppWhisperer, Joanne worked extensively in print journalism and photographic publishing, including roles at a paparazzi photo agency and as deputy editor of a leading photography magazine. Her freelance journalism, criticism, and commentary have been published widely in both the UK and the US, with bylines in *The Times*, *The Sunday Times*, *The Guardian*, *Popular Photography*, *NikonPro*, *DPReview*, *Which?*, *Vogue Italia*, *LensCulture*, the *BBC*, and more recently, the *Financial Times*, where her published letters on photography continue to contribute to wider conversations around the medium.Alongside her editorial and curatorial work, Joanne’s own photographic practice has been exhibited internationally across the UK, Europe, South Korea, and the United States. Her work increasingly explores themes of grief, loss, death, memory, and the body.Her current research interests centre on grief, death, and poverty, with forthcoming postgraduate study leading towards doctoral research in these areas.Joanne is currently developing new long-form writing and photographic projects and is available for commissions, editorial projects, speaking engagements, and collaborations.Contact: joannetheappwhisperer@gmail.com)
