Hello everyone!
Two weeks ago I bought a Sony a5100 with 16-50 lenses (Model SELP1650), but when I started filming I noticed shadows around the image.
I researched forums about the problem, and saw that it could be an effect called 'vignette'.
I shoot with the setting 1/80 F5.6 and ISO around 400 to 600 (with 3 lamps of 60w in a room of 3 meters by 3 meters)
and I was recommended to set the camera to 1/60 F11 and a higher ISO (around 2000)
I put this setting, but with the ISO increased, the image is very saturated.
Is there any other solution to remove these shadows?
The camera is very good, and the focus is fast, but this problem with "shadows" (or "vignettes") is putting an end to my filming.

Configurations: 1/80 F5.6 and ISO around 400 to 600 (with 3 60w lamps in a 3 meter by 3 meter room)

    • Hola, parece que estan agotados, saludos Felipe 
    • I'd suggest you start by running a simple test.  Take pictures of a typical scene/subject and each of the JPEG settings your camera offers.  Then compare them in the output that you normally produce.  You may or may not see a difference.  I normally shoot at the highest JPEG level and save that file -- but make a smaller file (lower resolution) for normal/typical use. There's plenty of editing that you can do with JPEGs on your computer -- depending on your software -- and there are features in your camera that can help out, as well.  That depends on your camera.  Put them together, and it might meet your needs.  For example, your camera probably has several bracketing features that will take the same shot with different settings with one press of the button.  Then you can select the best JPEG to work with on your computer.  I frequently use this feature to control contrast.
    • If you set up some basic presets in your processing software and use batch processing, you don't need jpeg at all. I shoot RAW only, use (free) Faststone Image Viewer which will view any type of image file to cull my shots, and batch process in Darktable. I can start with 2000-3000 shots and in a matter of a few hours have them culled, processed, and posted. A handful of shots, say a couple hundred from a photo walk, are done in minutes.  This saves card space, computer space, and upload time.  The results are very good for posting online. When someone wants to buy one or I decide to print it, I can then return to the RAW file and process it individually for optimum results.  I never delete a RAW file. Sometimes I'll return to an old shot I processed several years ago and reprocess it. I have been very surprised how much better they look as my processing skills improved.
