Canon SX50 - Camera RAW photos are really grainy

a couple of questions here. I just purchased a Canon SX50 because I wanted the option to shoot in RAW. I'm finding that when I process the images in Camera RAW in Photoshop Elements 13, the resulting photos are VERY grainy. Also the colour is not "true". I compared shots taken by my Nikon Coolpix p510 which only shoots jpegs and those photos are vastly superior to the photo of the same flower I shot with the new Canon in 2 ways -- the Nikon colour is exactly true to the colour of the flower. And the Nikon jpeg is much less grainy and the photos are sharper. I also shot the photo on Auto on the Canon - same result - the photo is grainier and the colour is not true. Am I doing something wrong? or is this just how it is? What software do people use to process RAW photos? I was told that the ACR in PSE13 is very accurate. I tried the software that comes with the camera and it's very confusing.

If I can offer some constructive criticism...

My wife and I have shot the sx 50 for 2 years now and have not had this problem...in fact she has more of a grain problem with her d5200 and sigma 150-500

First of all you are posting 3 different pictures from different perspectives...that wont work for a comparison.

You need to check the download box so we can really see whats going on...

Check your ISO setting the sx 50 does not handle high ISO very well.

Sorry to say your third pic is out of focus.

Lots of folks here can help you...its a great little camera...so if you have any other questions don't hesitate to ask...

so how do I avoid that grain -- yesterday I edited over 100 pictures in CR and noticed that each and every one of the macro photos were very grainy. I took them in a bright room, lots of light. I'm wondering if I'm doing something to them in CR that causes the graininess? For a while, I had the P mode set to raw +jpeg. The jpeg was always better than the CR taken at the same time - by better, I mean less grainy.

f 5 1/60 ISO 80

Don't get disappointed in this camera quickly...like I said ...my wife and I shoot some heavy stuff...

But she always carries the sx 50....

A "bright room" still might not be enough light. I just tried a test shot in my bright living room and it went to ISO 640. A big difference in noise from the one I posted below.

Please post some shots with "store original" checked (and don't downsize your image too far; if it's 800 pixels or smaller, the download won't work).

For the 'best' answers, click on "Reply" and attach those photos again, but at the far right side click on the box (store original) so we can see the full size photos and the EXIF data.

Hi Linda,
I went back and looked at all my macro shots from yesterday that turned out grainy - all were shot in P mode RAW - some inside and some outside -- they all had an ISO of 5000....so I guess that's a problem -- though why they would need such a high ISO outside in fairly bright light (slightly overcast) I don't understand. Another thing I find puzzling is that the thumbnail of the CR in the Finder shows a perfectly lit photo but once CR opens it, it's very dark -- I'm going to start by attaching those 3 examples -- then I'll upload some other shots for you to look at. Thanks.

LParis,
I just got an SX50 last week and the first thing that I figured out was that it does not play well with high ISO. It takes some really great shots, just keep an eye in the ISO and you'll be fine.

The settings are definitely strange - ISO 5000 with shutter speed 1/2000 sec and highly overexposed on that last (river) shot you posted. Did you happen to move the exposure compensation wheel/button by accident?

At this point, I'd go back to factory settings: menu, then the middle tab (wrench/hammer), near the bottom "reset all."

Put the knob at top to P. Go to menu settings:
servo af - off
ISO auto settings - set to max ISO 1600, and rate of change "standard."
Display area - small

Func button on back, going down the list:
set to auto white balance
center weighted average (metering)
4:3 aspect ratio (gets all your pixels)
raw+jpg
L for file size (4000x3000)

Double check that your exposure compensation is 0 (top of wheel just above "func set" button. And button below that, set ISO to auto.

Then I would use P mode and do some test shots. Maybe do some in both macro and regular.

Then report back :) And don't forget to select "store original" when you put on UHH (you did not on your last three. If you DID, then your file sizes are too small). Upload from a computer, and at 1 - 4 MB.

Best wishes!

High ISO and close cropping will always show more noise. That's the best I can do.

You are in fact looking a raw file and they never look good. As the name raw implies, they are raw data and need to be processed. A jpg has been processed by the camera and why it looks better on the screen. Now you need to hone some skills in post processing to take advantage of the 12-14 bit raw data.

As to the grain issue, no one can help without knowing what your settings were. If nothing else just export a pic to jpg and see how it looks re grain. if you can post either a raw file or at least a decent sized jpg with store original checked, we can do a lot more sleuthing.
