Yeahbut... no one said Cokin was crap (I've got a boat-load of 'em and use them all the time!), they're not Lee or Singh-Ray, but they're definitely NOT crap. "Crap" are those $10-20 sets on flea-bay from Hong Kong.
Those Cokins I used in those example shots all cost between $15 to $25 each. By any measure, they're common, cheap filters. They have a bit of a magenta color cast that needs corrected in camera or in post even. But that doesn't make them useless
crap, the way some folks around here would have people believe.
And by the way - based on WHAT exactly??? They don't seem to own nor to have used them, so what are they basing their "advice" on? Not experience, I guess. Or maybe that's what they had when they were noobs without a clue, shot clueless noob-crap photos, blamed it on the gear, and are still blaming it on the gear. Don't know and don't care. All I care about is cutting through all the
CRAP and getting to the truth.
Every time this subject comes up around here, some "know-it-all" makes claims that you've got to have $100 or better filters, or - better yet - $400 filters, or you'll have
CRAP for photos in the end, and I'm sorry, but it's just not true. Same thing goes for kit lenses and, again, sorry but it's just not true. Same thing happens for lots of gear around here, and it's usually not true.
Are kit lenses and inexpensive filters just as good as the top of the line gear? No, of course not. But neither are they usually
CRAP. Crazily enough, they often get the job done, get it done well, don't cost a beginner an arm and a leg to try out a technique, and are very valuable to learn with, and cheap enough for someone who doesn't have a lot of money to spend to be able to play and STILL get good results.
I think it's just plain wrong to lay those
CRAP OPINIONS on newer folks who come here looking for
accurate information, so I like to give the other side of that opinion and advice, complete with
actual examples of what kind of
crap one can actually expect by using the actual gear in question.
But maybe that's just me...
