Funniest phrase I've read in a long time. :) Brings to mind all kinds of ... interesting ... subjects.

Not sure if its been mentioned, but when going for grain in your shots, one should turn off the noise reduction feature of your camera, if it has one.

As an ex- (and current) film shooter I love grain:

(These are all scans of film-shots.)




(The last one was shot with some junky, expired Fuji HQ 100 that I bought in bulk and used explicitly for shots where I wanted a lot of chunky grain for effect.)

But I tend to agree with those that don't find digital noise appealing. When I want to add grain to one of my digital shots I use a scan off of a blank, exposed frame from one of my old film shots and layer it in using Photoshop. Works great, but not legal under any of the rulesets on DPC (at least as far as I can tell, since it utlizes multiple exposures to do), so I guess I'll have to experiment with shooting at high ISO.

Woo hoo! I'm in. I'm not sure if it's better than last time, but I do like it and I think the grain enhances the shot. And there is grain there, believe me! Lots of it!

Please tell me I'm not the only one who stoopidly forgot to reset the ISO after shooting for this challenge!

Just ruined a bunch of shots that should not have been at a high ISO. AGH!

Much harder, Urfa, but very interesting in terms of trials.

Heh ive got a really good idea, its gonna require an LCD and some black pants lol

I conformed about adding noise feature, It's OK with basic editing.
 03/11/2007 09:03:25 AM · #84

Well that was my one and only attempt at noise and grain and i did get some good reviews ( though not at DPC) so i am tempted yet in doubt

No salmiakki, you're not the only one. Fortunately though, I have taken nothing impressive so I'm not losing anything. But....thanks for reminding me because I still have not reset the ISO.
Going to do that RIGHT now!

So the final ruling is: the only legal effects filters are Noise and Gaussian Blur, right? No other photoshop effects are legal in basic?

There was no official ruling so we are left to guess on our own.

Let us recall that Photomatix tonemapping has been accepted as legal in basic editing. I would certainly think this could be interpreted as an "effect".

So let me go on the record to state I am using Artistic>Film Grain in my shot. Photographically I cannot do otherwise and there has only been silence from SC on this (even PMs have met with wishy-washiness).

OK, thanks. I think grain is different than noise and has a much nicer effect (can't remember). I'd hate to go with 'grain' instead of 'noise' and get DQ'd. I guess I will play with it and make a judgement call. Thx Doc.

This is why God gave us Post-Itâ„¢ notes :-) When I am shooting some off-the-wall setting, I slap a note on the back of the camera reminding me to switch back.

:) Of course - never seem to have them immediately to hand. Probably a good idea to throw a pack in my camera bag.

Right, they have the little tiny ones that have flags on 'em in a handy, tiny little dispenser. I keep a pack in the camera bag. Office Depot is your friend :-)

You must have plenty of room in your camera bag or the strongest Post-It notes available...seems like they'd fall off the camera when you put it in/take out of your camera bag? Unless of course, you change your settings before putting the camera away. :P

Nice tip BTW. :D

I think its funny that DNMC for this challenge will be a sharp clear image. i.e. The type of image we normally strive to achieve.

I guess its still got to be sharp (i.e. not blurry) but noise is desirable here.

Anywho

Hmm, I was just having a conversation this morning that sharp may not be good in this challenge. Grainy images from film were not sharp as a product of the larger grain sizes. Fine detail and grain may clash as well. But that's just my 0.02

Well if the last Image Grain challenge is any indicator it doesn't seem to matter much. I saw several in the top ten that were sharpened normally and at least one that I would consider oversharpened. About the only thing I would conclude is non-sharpened photos may have a little more of a chance to do well then normally but that's it. In the end, the content will drive it not the sharpening or the grain but I've been known to be wrong on many occassions. :P

unsharp mask can be used to simulate grain, but i dunno how well it would fly.

this was my first entry here.

i'm extremely excited about my image ;) tres' good ;?

That will be my filter of choice as well, in lieu of a pre-challenge ruling (the only drawback is having to go 8-bit to use it).

I wonder then if other noise/grain generating filters are therefore okay, such as Fred Miranda's BW Workflow Pro? It "only" adds up to ISO400 grain, but used in conjunction with Artistic-->Film Grain makes for a more natural (i.e., film) look.

Sorry for the confusion and the very late reply, but this is what has been decided by Site Council after much discussion:

both "film grain" and "add noise" are OK for the challenge, but that "grain" under textures is not. Equivalents of these Photoshop tools are also OK.

Thanks Love...makes my day.
