Black bear with curious

Gallery: WildlifePosted July 11, 2014117 views2 comments
The picture was taken in the Kootenay NP in Canada. One of here two cubs took a curious peek over its mothers back.


A lot of information is lost when resizing the picture to 300kb or 500kb. Any recommendation on how to get a sharp picture at this size is highly appreciated

Hi Reiner,

Yep - mom looks pretty intense and interested, and junior does look real curious! The image has instant appeal with mom and cub in same frame and having junior looking over mom from behind adds extra interest. The image does feel over-exposed a little to me and thus a little washed out - I suspect if you pull the exposure on this one back globally by 1/3 to 1/2 stop I suspect it will "come to life" more. The image does feel a bit too tight on the bottom for my taste...but that's a personal preference issue.

You ask for a recommendation on how to get a sharp image at 720 or 1200 pixels. Without knowing what software you're producing these with (i.e., which program you're using to re-size them for NPN), it's hard to get too specific. But, in general, all images that are destined for the web need to be specifically sharpened for web use. This usually means picking a pixel radius significantly smaller than if sharpening for prints. For instance, if you're sharpening at 0.7 to 1.0 pixel radius for print, that same image should likely be sharpened at 0.1 to 0.3 pixel radius AFTER it has been re-sized for web. The AMOUNT you have to sharpen it for web use will vary with the image, but values in the 100% to 200% range often work well. A lot of variables do impact on sharpening technique for web - everything from how much sharpening has been done during your initial raw conversion (assuming you're shooting in raw format), how much cropping you're doing, what algorithm was used during image resolution for web (e.g., bicubic vs. bicubic sharper), and even what camera you're using...

Perhaps if you could describe your workflow (including what software you're using) in getting your images down to the right size for NPN then you could be given some more specific tips and settings that might help you...

Cheers...
