EOS Bodies - For Stills / Re: 7D Noise Reduction Tips
« on: January 23, 2013, 02:24:23 PM »
First off is to remember the 7D has a light hungry sensor. Correct exposure is the key particularly at high ISO's. It is not forgiving and underexposure at high will not yield good results.   

You have two key sliders in PS - Color and Luminance. DPP calls Luminance Chrominance which is actually correct.   

ISO 12,800 with no NR. You should always do this at 100%.



ACR sets Color NR at a  default of 25 you can increase it until the color blotchiness goes away. Sliding any higher when it is gone as it does not gain anything. I find 25 is pretty good and usually leave it there.

You can see the difference between the color blotchiness between the first image and this one. I set Color to zero in image one so you can see the difference.   



Now you use the Luminance slider. This gets rid of the grain or noise. Be careful with it because it effects the image sharpness. The higher you go the less sharp your image will be. You will really notice it when you sharpen it. It is upi to you how you want to balance sharpness vs NR.       



A little more detail.

Also in the sharpening sliders you will see a slider called masking. If you hold  the option key (mac - not sure about PC) and move the slider to the right you will see a lot of white at first. The further you move the slider more white disappears. At around 80 you will see very little white, only around the edges. These white edges are the only thing being sharpened. The black background will not be sharpened. Not using the masking slider only sharpens the existing noise in the background or other unwanted areas. I'll se if I can find a visual example of this.             

All the above works in LR as well.

Next I like to use this method. Another edge sharpening technique. I don't use it for mass edits in LR as it takes too  much time. I just use it for hobby shots.

Great pics. Shows how much of a fantastic camera it is in the right hands.

Thats correct as the 7D is in a price gap that is very affordable compared to the FF equivalent but is aimed toward more advanced/pro shooters and the attitude amateurs have toward glass. Therefore many marry the camera with poor glass. Just because it is EF-s putting the cheap inexpensive glass on it will be detrimental. But many think cameras are more important, especially some that aren't photo buffs but like having the best.

This was always my qualm with Canon and its 18mp sensor as all the recent XXXDs and 60D have it too. Unless quality glass is used to resolve that pixel density then yes the camera wont perform well in terms of IQ. Give it high end lenses and the camera sings, but then it does have its drawbacks. There is always a compromise, add more IQ and it creates a slower camera at a higher price point. The 7D hits the spot pretty well, as long as you are willing to hunt for the light and spend some time editing the RAW files in post.

I enjoyed the 7D but it wasn't quite what I wanted and needed for my work, although I wish I had kept it and used it with my 5DMKIII.

In all honesty I almost did not buy it. Don't get me wrong because I do appreciate the resolution for cropping, etc but I think if Canon had kept it at 15 megapickles coupled with the new sensor tech no other manufacturer could have beaten at that time. Stall a bad a$$ today and would have been even more at it's release.

I had all the 5D series and have the 5D3 as well. Both bodies have their places and uses.

I have the double. I used to have the single and never had any issues but then started to read about a few mishaps. Mostly human error or failure due to a knock off. As for error people forget to lock the carabiner.

Quick release clamp
 


I put a key ring chain ringy thing just as a backup here. I don't need it to swivel, just slide.

I just got my 5D3. I had no problem shooting 6400 with my 5D2 but have not tried higher than that on the 5D3 yet. NR for all images using CS6 or LR

5D2 @ 6400 with flash





7D @ 1600



7D @ 12,800

How often are you going to be shooting in a studio situation so dark that your camera won't be able to AF?  And if you do just get a modelling light or small LED flashlight. If you are in a studio you have time.

I 'm very happy with my ST-E3-RT.  When in studio it sits on the camera. Well actually I carry it around with me, set it to group, shut groups off as a I work on others, use the test button to fire the flash or flashes (meter with Sekonic) and when I'm done it goes on the camera.

When I run and gun shoot the flash goes on the camera. I have two 600's and am going to get a 3rd soon so when I run and gun I will have two other flashes working.

I modified the mini stand that came with it (ordered a replacement) and strap it to my belt/pant belt loop. I cut it down so it was just big enough for the job.

« on: January 19, 2013, 12:12:20 PM »
Yeah. I tried that. I can't can't properly support my 5D3 & 24-70II unless I eat some spinach. Popeye to the younger members which you may never heard of anyway ;D.

235
I have yet to test this in the real world but will be getting a chance soon. I was very happy with my 5D2 but wanted the pro AF the 5D3 offered. If I run into this there won't be a 5D4 in my future.

Yes they do to some degree and I know the 600EX-RT patterns are designed to work with the 5D3.

Hello All,

Please remember to post your findings onto this link also, http://forums.usa.canon.com/t5/EOS/5D3-AF-assist-beam-slower-focus/td-p/2277 Its Canons forum, so far we have had Canon respond twice, the more we help them look into this, the more we may get a solution,

all the best

Louis

Considering the amount of posts and information that is already here in this thread and several other threads, what do you think the chances are that someone from Canon that is reading the posts on the Canon forum might simply click over and read  the CR threads if the links are posted on their forum?  Just sayin'...

I think a major issue is this has been basically ignored at both DPreview and Fred Miranda. DPreview has surprised me as they usually latch on to these things like a Pit Bull. Big players in online forums with little noise so far. Does not help this cause.

I don't know anything about this manufacturer. Where do you see that it reads colour temp? It will give you correct camera settings for both flash and ambient light. So does my Sekonic.


239
Did the revup  ever say what camera body we are discussing on this thread?  The signature says both 5d3 and 7d so is it one of these?

I ask b/c I just sent a 7d for canon service for high noise but it also had grain in excess.

I'd bet it was the 7d. I hate that sensor, personally.

Too bad. I like it.

Sekonic L-358 is a very good and popular unit. I own one. The particular one does not do a temp reading. Don't know about others but fi they do they will be expensive.
