Street & City / 5D3 and ISO 51200: Firefighters rehearsing Emergency
« on: October 15, 2013, 03:04:27 AM »
Yesterday night, volunteer firefighters rehearsed an emergency case. The 5D3 did pretty well at very low light with a Canon EF 85 F/1.8 USM wide open. DPP: Luminance NR: 11 Chominance NR: 15

EOS Bodies / What's to be expected from Canon in Q4 2013?
« on: September 17, 2013, 05:25:34 PM »
Hi folks, what do you think? Are there any DSLR or Lens announcements left for this year? Or if not, will 2014 look similar to 2010 with a Rebel and the 7DII instead of a XXD?  ;)

EOS Bodies / 70D and Dxomark....
« on: August 28, 2013, 04:53:57 PM »
70D and Dxomark... As far as I have learned here on this forum, their assessment is not the last verdict...;-)

full moon, yesterday, somewhere in the foothills near my town at 4500 ft. my first panocturne. 6 Raws batch processed and photostitched in DPP. slight PP in CS2. How can I improve this process? Anyone? Especially to get equal luminance values in every frame? Anyone? Going for LR 5 within these next month. In addition to LR, which pano software are you using? Thanks for any help.

EOS Bodies / Still no news about a Canon shift in sensor fabrication?
« on: July 08, 2013, 07:19:20 AM »
Was just browsing the net and didn't find any news about a probable sensor fabrication shift (from 500 to 180 nm) by Canon for its newest camera body. Can it be expected by 2014 along with a rumored 7DII? Stumbled upon an older but intresting thread at this forum instead

Hi everyone,

Tested my 16-35 F/2.8 USM II and my 50 f/1.4 on the 5D3 wide open at low light and 51k ISO. The 50 f/1.4 had the edge exposure value wise. As I took the pictures at about 20mm I thought I could gain some aperture using a Sigma 20 F/1.8. I read the reviews at (see Nikon part). They were not very flattering. But due to the price I just think, why not? Is there anybody out there shooting either the 20 or 24mm siggy?

Thank you for any advice

EOS Bodies / From NL: Big Product launch invitations
« on: June 26, 2013, 05:20:46 AM »
From NL, what might this include? Hope it hasn't been posted here yet.
"We're told (thanks) that Canon have been summoning inviting some people from dealers for a 'big' product launch within the 6-8 week timeframe. If so, expect to see some more serious leaks within the next couple of weeks. No details of just what was meant by 'big', since in PR speak that could be anything!"


I do some nightphotography on my 5D3. It is still amateurish because one always can improve.
After having seen this tutoring video

Curves and Levels - Easy 123 - Photoshop Astrophotography Tutorial

I am keen to do this myself. It is about curves and levels in Photoshop to enhance the data. My version is CS 2.

But there arise a few questions:

I downloaded deep sky stacker. stacked seven colour pictures: copies of the same photograph to give it a try.

This guy in the video starts with a greyscaled stacked picture. Others I've seen worked at RGB mode.
How is he getting a greyscale type of stacked photographs as mine turned out to be colour? It never looked like his in the beginning. Here's my slightly enhanced original picture

I guess it kinda deals with RGB channels. But I have no clue how to do it, even my curves and levels don't react the same way as his.

Is it a presetting in PS which he applied without mentioning it?
How can I do it in CS 2?

Thanks for any technical help.

Just another question: at what ISOs are you taking nightsky photographs for stacking purposes?

I currently take them applying 600 rule at ISO 6400 to 12800, f/8 with a 16-35 USM II lens.

Cheers and thanks in advance, Peter

EOS Bodies / Testing my new 16-35 at ISO 51k and 102k
« on: March 24, 2013, 07:34:57 AM »
just bought an excellent 16-35 F/2.8 L USM II second hand and tested it at insane ISOs yesterday...
My youngest son liked it...After a few tests in the past six month I guess, if you wanna get a decent b/w, 51k for the 5D3 is the limit with a light source like this. But I am more than happy, to be able to push things that far. Everything done in DPP, NR at about 14/18.

Reviews / 5D3 Nightshot at ISO 102400
« on: February 23, 2013, 01:05:30 PM »
Last saturday I was taking my 5D3 to the extremes. I took a picture at 1.3 sec, f/8.0 using my knees as a tripod, huddled down on the street. I know it is noisy like an old B-52, but I kinda like to take it to the limits... 8)

In case you did that, I would like to see your 102k pictures!

Cheers, Pedro

EOS Bodies / What if the rumored 5Dx is actually a 4D?
« on: February 14, 2013, 04:25:08 AM »
Hi, returning to CRs post a few days ago:
<div name=\"googleone_share_1\" style=\"position:relative;z-index:5;float: right; /*margin: 70px 0 0 0;*/ top:70px; right:120px; width:0;\"><g:plusone size=\"tall\" count=\"1\" href=\"\"></g:plusone></div><div style=\"float: right; margin:0 0 70px 70px;\"><a href=\"\" class=\"twitter-share-button\" data-count=\"vertical\" data-url=\"\">Tweet</a></div>
<p><strong>A new EOS-1 body in 2014<br />

</strong>The latest we <a href=\"\" target=\"_blank\">and others</a> are hearing is that a large megapixel camera from Canon won’t be coming until 2014. This coincides with information that Canon <a href=\"\" target=\"_blank\">would be releasing 3 DSLRs in 2013</a> and none of them outside of the APC-S segment.</p>
<p>Prototype cameras with sensors beyond 40mp do exist and are in the hands of very exclusive testers. However, we’re also told that a few lenses in the lineup will need updating before a large megapixel camera hits the market for Canon. No specific lens was mentioned, but I would imagine a full frame ultra wide zoom is one of those lenses.</p>
<p>From the same source as above, 4 new EF lenses will be coming in 2013.</p>
<p>Canon’s announcement date for a new EOS-1 may be dependant on when Nikon announces the rumoured 36mp D4x, Nikon cannot have two such cameras on the market while Canon remains quiet in my opinion.</p>
<p><strong>EOS 5D X?<br />

</strong>A faster update? One suggestion from a known source is that Canon has loose plans to replace and/or update the EOS 5D Mark III quicker than the previous iterations. Could we see one some time in 2014? I would think a direct replacement would be unlikely, however a small, high performance & higher megapixel DSLR would probably have a place in the market.</p>
<p><em>*Notice how I didn’t say “EOS-3D :)”</em></p>

So, concerning the last paragraph of his part of the original post, what if the rumored high MP body is actually a 4D?
CR guy: - any additional thoughts? Is it likely to happen?

So the 5Ds could maintain a relatively "low" MP count within its segment as a higher priced allround cam. If my memory isn't too blurred, Canon kinda hinted that after the 5D3s announcement. Not sure what the original message was, but somewhere along the line, that they consider to stay at these MPs in relation to the feedback of some photographers. I would happily embrace such a decision. So a 4D could be the 1DX equivalent at high MP and DR. Well, time will tell. Cheers, Pedro
