Two days ago, I bought a lens adapter so I can use old Nikon Film lenses with my camera. But the night before that, I cleaned a 50mm prime lens myself. I disassembled it and reassembled. Yeah. I know about the do-not-disassenble-lenses-or-else-you-risk-getting-lens-elements-out-of-alignment but I still did go about disassembling it. The huge screws on the metal mount of the lens was very tempting.I bring along my camera and the 50mm f/1.4 attached to it every time I go out so I can do some test... continue reading

And also how to get rid of it using lightroom 3? I've been searching in youtube but didn't find it. Thanksalot! continue reading
Aberration, also known as “color fringing,” refers to the effect in which light passing through a lens becomes blurred and produces a fuzzy image on the film. If the camera lens is unable to focus light of different wavelengths or if the lens is scratched or otherwise damaged, chromatic aberration of the final image will occur.In a normal lens where aberration doesn’t occur, the lens directs light of different wavelengths to specific areas of the film, depending on the particular wavelength.... continue reading
Chromatic aberration appears in photos as "fringes" of color along boundaries that separate dark and bright parts of the image and can be most annoying.Even with Canon L glass and a reasonably high end camera, I'm still faced with it in certain situations - with trees against pale skies, for example, or the edges of a building against a white sky, or blue sky with clouds.There are times when even my software (Photoshop CS5) can't completely eradicate it, so I've figured out a fix which works... continue reading
Since many lenses can not focus all colours to same convergence point, Chromatic Aberration becomes a major problem for many photographers.If you are shooting in RAW mode , youhave the chance to get rid of this fringing in your raw editor.However in some cases when you forget or dont like to make too many chances in raw editor , you still have another simple way to clean these dummy lines in different colors with the help of Photoshop.1 - Open your image with fringing2 - Copy background... continue reading
Hi would like to share my little knowledge about eliminating those awful and refusal-reason lens fringing on some photos (usually red and green colors by the edges of tour objects). I have made with my snow photos.I took a lot of snow photos by the 8th march big snow that took place in Barcelona, and had a lot of refusals because the damn lens fringing, so what I did:Requires a lot of patience:)1) Open the picture in Photoshop and zoom 200% or 300%. You can see the more visible chromatic... continue reading
I just looked at my most recent rejections and the reasons for the rejections.I could understand most of them, which were things like: "poor lighting setup", "poor contrast or incorrect exposure", "white balance parameter not correctly assigned"...and then there was this one: "poor optical performance due to low lens quality."A lot of my files were rejected because of lens fringing and chromatic aberrations.I researched what lens fringing was and apparently the lens I'm using does not have... continue reading
Just wrote a new post at my blog twcdm.blogspot.comHere is a sample of that post.Purple Fringing, AKA: Chromatic Aberrations (sounds like something you would hear on an episode of X-Files), AKA: Lens Fringing. Even with the best lenses you will occasionally find these little buggers lurking amongst the edges of your photos. Purple fringing usually shows up as purple halo's around objects in the edges of your photos. Luckily there are a few easy Photoshop fixes you can do to get rid of... continue reading
