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 photozone.de (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
Peter

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!"

Hi,

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 Small | Large


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 »
Hi,
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=\"https://twitter.com/share\" 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=\"http://www.northlight-images.co.uk/cameras/Canon_1D_Xs.html\" 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=\"http://www.canonrumors.com/2013/01/canons-roadmap-for-2013-cr2/\" 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>

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

Hi,
My 5D3 is a great cam. Coming from the 30D I set its AF by suggestion of my brick and mortar dealer on the center AF point. In 90% of the cases it works great.
But compared to the 30Ds center AF point which was quite snappy even at very distant and dim light in moonless nights, the 5D3 AF is struggling a bit. Still being in my learning curve since August, what are the mistakes by my side while handling my gear.
AF on the moon: no problem.
AF on Jupiter: mostly no problem.
AF on some distant, dimmer light at full darkness...not always working.

Guess I've read about slight issues here, so thank you for any help
Cheers, Peter in Switzerland.

Reviews / 5D3 shooting my cat at ISO 51k at 6:30 a.m.
« on: January 11, 2013, 07:55:55 AM »
Hi, I know it has been done before. But this morning I was shooting my cat at ISO 51200 in an almost dark bedroom at 6:30 a.m. today. Canon 5D3, Canon EF 50 F/1.4 @ F/1.6, 1/40 sec. While a small amount of ambiental light fingered into the room I manually focussed at the animals ears which I saw better than it's eyes, therefore the face is slightly out of focus. Photograph above: no NR applied. Photograph below: NR value in both Luminance Noise & Chromniance Noise: 14 out of 20 in Canon's free software Digital Photo Professional. This goes way beyond my wildest enthusiast amateur dreams! Watch it in full mode, although due to reduction in post for webupload the difference is less obvious. But the pic without NR looks as grainy as back in the filmdays...But that's quite awesome at these ISOs! 8)

Hi, although my bank account is set up for saving, just a question towards the professional and more advanced photographers out there: As how important do you consider the additional 2mm on the wide end which will be offered by a rumored 14-24 f/2.8 L. Does it make a big difference or what would you do? What are the probable advanteges on the wide end?

As an enthusiast amateur I am on a budget and first considered the Sigma 12-24 f/4.5-5.6. But it is a tad too slow for my nightphotography preferencies: nightscapes and milky way preferably during moonless nights.

So, maybe I'd go for a 16-35 instead which as equivalent to the Canon EF-S 10-22 on my former 30D expect the difference in speed (about one stop, but permanently). The price tag surely will be another argument, as it will be considerably higher than the one of the 16-35 f/2.8 L (CHF 1361.00 online over here).

Thanks for your advice. Cheers, Pedro.

Hi all,

I bought my 5D3 by the end of August still at a premium from a reatailer nearby.  While I am using it at every possible high ISO including 51k and 102k for b/w I just like to ask the experts here, what can be expected in high ISO IQ and sensor tech by the time the overnext 5D (whatever it will be called)
hits the shelves?

Is it likely to make ISO 51 k look like today's ISO 12800 or 25600? this would be like one or two stops better high ISOs.

Cheers, Pedro

I really like the 5D3, here's a nightscape at ISO 10.000 (slight NR)
