But what is the real world effects of having scratches and chips in the glass? Does it really show up in the image or is it merely cosmetic? I'm sure there is some psychological reasoning to wanting to have immaculate glass all the time, and having such scratches and even chips would rub most of us the wrong way, hence wanting to sell and replace the lens altogether.

I just bought a really nice lens for a very good price due to the fact it has a few chips and scratches on the front glass.
However, the seller states it has no effect on the image quality.
So I received the lens (a Canon FD 85mm F1.2 L), and initial tests do not show any signs of the chips or scratches, which is a win for me.

Does focal range matter concerning if the chip or scratch will show up in the image? I'm sure for macro lenses it would affect, but telephoto lenses might be more forgiving.

Anyone's thoughts and experiences in using chipped or scratched lenses, please provide!

]]> Scratch Play, free and powerful media player https://personal-view.com/talks/discussion/8059/scratch-play-free-and-powerful-media-player Mon, 09 Sep 2013 21:01:19 +0000 maxr 8059@/talks/discussions Stumbled upon this piece of software and thought some of you, fellow foruners, may find it of use :-)

So Assimilate has released this free player called Scratch Play for both PC and mac and I must say it is really a mighty and useful one.

FORMATS natively supported

and PLAYBACK

AUDIO abilities

COLOR, now here's where starts to shine

MONITORING

and best for last EXPORT

Cutting long tables short, or not, you can watch (and listen) footage of almost everything, with metadata and SCOPES, LUTs and whatnot. You can compare between 2 clips, same clip at different time, sizes, with different colour settings/grades applied, different color spaces, LUTs, source mode mapping (Lin to Log, viceversa and Lin/sRGB, Log/Filmm Rec 709, Wide Gamut, etc. you can even load yours), 8, 10 and 16 bitdeph, different frame rate/speed (from 0.1 to 199), with different frame size or aspect, offset, with guidelines (2:35, 1:85, etc.), crop marks, color full range and gamma, timecode and 3D baby jesus snorting coke LUT if that's your thing. Here's another cool feature: you can export your LUTs. You can visualize RGB channels plus luminance or alpha only. It supports dual monitoring, makes fullscreen either in single or compare clip mode, you can completely fade borders, guides, etc. Scopes can be transparent or solid, has dedicate snapshot button, a magnifier... for sorting buggers :P and pressing tab (on mac) hides panels.

Now the "drawbacks" it is free with little stupid adds, you'll need a fairly decent powerhourse for all-in smooth performance, you may, just may like it.
