EOS Bodies - For Stills / Re: Is there any reason to shoot sRGB????
« on: November 25, 2014, 04:48:04 PM »
If you photograph in RAW and obviously post-process, then the colour space setting in the camera is irrelevant.

Not quite:
1. the histogram is based on this setting, with adobe rgb you get a better representation
2. in every cr2 there's a full jpeg thumbnail with the color space selected.


very interesting, thank for info  :o

When an sRGB device encounters another colour space, it will usually convert said other colour space to sRGB. Conversion is never 100% successful.

Ugh? How so?

he probably didn't mean conversion, but displaying Adobe RGB image in sRGB color space, to which some web pages are prone and then colors are shifted

Photography Technique / Re: uneven polarization
« on: November 09, 2014, 04:47:01 PM »
It's to do with the angle your camera is pointing with respect to the sun. Maximum polarisation occurs when your camera is aimed at a perpendicular angle to the sun.

Here's a link for you:

thank you for sharing link, it's great page and I went trough it already

You need to provide more than just general information to get a intelligent answer. 
 
What brand polarizer, sample photos, camera used, lens used, settings, etc.  Don't forget that the best brands are also big targets for counterfeiters, and there are a ton of B+W counterfeits out there that often have issues.  Its easy money for those who make them.

Gear I used is 5D mk III + 24-70 and 70-200 (in my signature  ;) ), both with BW kaesemann filter.

Both filters are genuine, I do not worry about this, both were bought from authorized dealer and also had hologram on case.

Basically is doesn't surprise me to see this effect when I'm using 24-70, it's quite wide on FF and I try to be carefull when using this lens with polarizer. More I was surprised to see this effect when I used my 70-200 with polarizer. Maybe relevant information is, it was in mountains when I noticed it(2000m+)

What I would like to know is how to prevent this situation of uneven polarization with longer lens?
How to solve this issue? Sometimes the reflection has to be cut with polarizer or colors need a little boost, but sky is then uneven ... do you take more shots? Or do you take a shot with and without polarizer to solve it?


I'm sorry not to upload any photos, if it's necessary I'll add them later (I'm not on my main computer right now)

Software & Accessories / my first zeiss glass
« on: November 09, 2014, 10:04:54 AM »
hope you don't mind this post, but I'm simply too happy about it not to mention

recently I bought myself a present for my B-day
however it's not a lens, but binoculars from zeiss  :)
to be precise this one
zeiss conquest hd 8x42

I posted it accesories thread since it was meant for wildlife spotting, I'm really happy with build and also optical quality and I highly recommend it to anyone who's in need for something similar. I tried it also in sunset and in really dark conditions and resolution and clarity is simply superb.

From now on I am happy zeiss customer  ;) :)

Photography Technique / uneven polarization
« on: November 09, 2014, 09:55:44 AM »
Hi guys,
on my last trips to mountains I encountered some uneven polarization effect. I was wondering, is there any way how to use polarizer and prevent from this effect? Or do you merge more shots to handle it in post processing?

I have heard many opinions that this effect should be more visible with focal length of 24mm and shorter, but I've seen it in some of my shots with FL longer then 70mm (even in some 200mm shots), am I doing something wrong?

EOS Bodies / Re: what is the body you want to see canon release next ?
« on: November 02, 2014, 04:30:44 PM »
I voted for 1DXII

I probably won't be able to afford it, but if Canon brings some new, overhyped tech, then it will be in 1 series body. After then we can hope some high resolution sensor with tons of DR or whatever upgrade will go to lower models.

I like it. The ice skein seems natural enough to me, a light overlay to the water. It may be that the foreground is a bit too prominent and detracts from the mountains which I suppose to be the primary feature. However, having said that, I do like the picture as it is.

thank you

Seems pretty impressive to my relatively untrained eye.  I'd like to see what you started with because the ice seems not quite right but maybe that's just what it looked like in real life??

Jack

what exactly doesn't seem right to you? I did only some saturation + clarity changes, oh and the stones were bit warmed up

Let me share my last lake/mountain attempt. It's my first shot where I tried manual exposure blending using luminosity masks + some light brush touches  ::)

I personally think it's little bit too messy content wise. Please, feel free and share your critique

Lenses / Re: missing reviews of 400mm f/4 DO IS II
« on: October 30, 2014, 09:28:13 AM »
There were lot of preproduction reviews of 7D mk II, but I'm really missing some more info about 400 DO II. It looks like a very interesting lens and I couldn't find any other info except introduction and short overview here

Am I missing something? Is it too soon for reviews? Or am I the only one interested in some sample images if not whole reviews?
Same to me. I can only find low res samples from Canon.

It seems that there are not so many copies out there that they could find their way to the reviewers.
Neither on Canon nor on retailer pages I can find any release or delivery date. Everywhere you only can pre-order.
Not that I could afford it, but I am interested in how the DO tech has been developed in the 2nd generation.

exactly, I'm not buying it, maybe in future as my wildlife lens, but right now I'm just curious about progress in DO development

Landscape / Re: Hoya Polarisationsfilter for Landscapes.
« on: October 15, 2014, 03:43:15 PM »
There are also much easier to clean.  Fingerprints wipe off very easily.  Within the Hoya line, I highly recommend the HD filters.

This is very interesting. I've got two of the Hoya Pro1 Digital filters and have noticed they are a massive challenge to get clean. I just end moving the oily smear around the glass and never really get rid of it. I always thought it was just my lens cloths or my technique. Good to know.

same here, it was PITA to clean the Hoya UV Pro 1  >:(

in my opinion, I think that B+W nano coated filters were the easiest to clean

A more expensive alternative is the B+W XS-Pro MRC Nano, but I do not know what the extra dollars are providing.
The extra dollars get you the Nano coating (tougher outer layer), brass instead of aluminum, and a slightly thinner filter (4mm vs. 5mm).
indeed those are some very fine filters, if you have money and want quality stuff, then don't hesitate and go for it ;)

Lenses / Re: wide angle needed
« on: September 30, 2014, 03:42:32 PM »
16-35 f4 is definitely what you want. Canon did an excellent job on that one.
indeed, already checking where to buy the lens  ;)

What about EF 16-35mm f/4L?
Or EF 20mm f/2.8?
Or EF 17-40mm f/4L?


all of them were already suggested, but anyway, thank you

I don't think you can go wrong with the 16-35 f/4 IS.  Along with the 24-70 f/2.8 II and 70-200 f/2.8 IS II, I think these are the most amazing zooms on the market.
don't forget 200-400  ;)

I can just add to what Macguyver is saying. I have the Zeiss 15mm and 21mm and they are both phenomenal lens, especially the 15mm, which I totally fell in love with it this summer. But the 16-35 f4L IS is a lot more versatile and the IQ is very impressive. Be also aware that the Zeiss 15mm has a 95mm filter size, so filters are not exactly cheap.

for me, the main problem, there is no way right now how to test Zeiss 15, it could be excellent lens, but I don't like the idea of buying lens for 2,5k euro before trying it
