Re: ten mile tree
Beautiful picture, Joey. No purple fringing along the branches at this weather (to get rid of in Photoshop)  |

Re: ten mile tree
Thanks Sjef. Didn't notice the fringe - and didn't know it wouldn't happen because of the weather! Is this one better?  _________________ "Art is a blade of grass ... and in a moment I will eat it." |

Re: ten mile tree
Doggone it, this wasn't what I ment, sorry about that. I found your first picture just fine with a lot of spooky atmosphere. The 'color shred' appoint to the whole sense of the picture. Your second photo maybe improved, but the first was all right for me. Purple fringing is a lens daviation which shows much more when the sun is shining. But I suppose you knew of course about this phenomenon. Expensive camera's deal with this inside their processor (not mine, so I use Photoshop for this job).  |

Re: ten mile tree
Oh what a lot of mistletoe! They get cleaned here. ..... sorry Christmas! Concerning fringing, my camera quite good but if use PS Camera RAW seems to resolve many problems with the profile of my camera. I have to do it in RAW - Bridge. Actually a very good job CS5. Really annoys me, but a basic fact of the sensor according to my understanding. I only have a small APS sensor. Lens is fine but if you shoot into the sky, we get it! Interesting, If I use polarizing filter it does not really happen. |

Re: ten mile tree
Sjef, you said "But I suppose you knew of course about this phenomenon."......well, no. I don't. I buy the best camera I can afford and count on it knowing what to do. I did much better with my old 35mm - unfortunately my RA doesn't allow me that option. Anyway - so glad you like the photo - you too, Trevor. We have some pretty amazing winters here in northern CA. Lots of photo opts. _________________ "Art is a blade of grass ... and in a moment I will eat it." |

Re: ten mile tree
Ai, now you're aware of this, maybe you're going to pay attention to it, which takes more time of your life 
And... this fringing wil not always be 'purple', mostly it's a magenta, cyan, blue or yellow edge. In Camera Raw (RAW) this edges will automaticly be found. In Photoshop (JPG) you can deal with it (1) using Hue/Saturation: click on the edge, and make it another (surrounding) color or set Saturation to zero (gray). Or (2) using the filter Lens Correction»Manual. It's possible though to load every JPG in Camera Raw after you set this in the Ctrl»K menu: File Handling»remove the check mark in front of 'Prefer Adobe Camera Raw for Supported Raw Files'. Or from Bridge of course. In CS6 the Camera Raw defringing option is further developed. To Jota: it's not the sensor, it's the (every) lens.

Joey > Trevor. We have some pretty amazing winters here in northern CA. Lots of photo opts. Lets have a workshop there then
Sjef : great advice. Re: "To Jota: it's not the sensor, it's the (every) lens I don't disagree, just stretches the boundaries a bit more. According to my understanding the RGB pixel sensors are on different levels on the CMOS sensor and/or have their filters above. Depends on camera. So poor little lens can't focus on whole lot of sensors at all wave lengths. Fine most of the time until you shot the sky. As you say it is up to lens fundamentally, but then it has to worry about different focal plans, especially with APS.. I'll send image that worked ok without correction Either way, everything ok for me to correct with CS5 to correct. |
