![]() ![]() This sounds like a good argument to shoot JPEG all the time. no sharpening, no white balance, no color profile, no de-noising, etc. That means the image has had any corrections or adjustments of any kind. It doesn't even de-mosaic the image into true "pixels" (that's up to computer software to deal with it). The camera reads out the image from the sensor and saves it to a file. When you shoot RAW, none of this happens. But it's been processed to clean it up (in the camera). What you get as a result, is a relatively clean looking image. so it applies white balance, it may apply color profiles, it will apply some sharpening, and based on the ISO setting of the camera, the camera anticipates a certain about of noise and so it will also apply some de-noising. When you take the shot, the image is read out from the sensor and, at that point, it would render exactly as the RAW (because it is a RAW even though you are shooting JPEG) but since you opted for JPEG, the camera gets to work applying adjustments. It's as-if the camera has a copy of photoshop in it and does some cleaning up of the image for you. When you shoot JPEG, the image you get out of the camera has been "processed". Exactly why all digital sensors have noise is a long topic (and some of it has to do with quantum physics) so we'll avoid that and just cut to the answer. The goal is typically to have a high "signal to noise" ratio (or SnR). The sensor is trying to collect photos of light (signal) and in doing so, it will also accumlate "noise". The "grain" you refer to is called "noise" in digital photography. This is doing my head in as I thought I had the settings and everything sorted during the shoot.Īlso if this isn't the right thread please let me know! First time posting and all. I hope you guys can help me out and advice where I've mucked up. Is the size wrong? Like should I reduce it to a smaller dimension? When this was reduced to 1500x1000px the grain wasn't so bad even with all the edits. Is the format of the image wrong? Should this be exported as TIFF instead of JPEG?ĥ. Did I overdo the image adjustments in Camera RAW and then further affected it in photoshop?Ĥ. Was the ambient light at the location throwing off the exposure which resulted to the grain? (shot around 3pm in the afternoon, lots of back light in the background)ģ. So what I'm trying to figure out now is this:Ģ. I'm not very confident to send this image to my friend as the quality isn't as smooth and clean as I've seen from other people. You can already see it from the second image attached. When the image is zoomed in 100% (full image size at 5760x3840px), the grain is really bad, especially around the hair and face. JPEG with slight colour adjustments and clearning on photoshop CC JPEG output from RAW with some setting adjustments (done in Camera RAW in photoshop) ![]() The below image was shot with the following settings: Manual, f1.4, 1/250s, ISO 200, 50mm. The images I've shot looked decent in RAW, grain isn't that bad, however once I start tweaking with the settings in Camera Raw(photoshop), the grain becomes rather obvious and it gets worst even with slight brightness/colour changes with photoshop. I'm not sure whether my original settings were wrong or that my sensor isn't clean. I didn't study or learn photography and most of what I know I learned it off the internet, so I'm still rather new to this. I've recently received a 5DM3 as a graduation gift and got myself a 50mm lens to shoot along with. I hope I'm posting this at the right thread, else please advise if this isn't the right section for this.
