  1. Noise

    Im confused about noise, I took some pictures at the weekend using my new ND1000 filters and the failed the QC test because of noise, I have looked at the at 100% and cant see the noise that has failed them, I cant share the pics because they failed, would it be because I used the ND filters, is there any way of finding out what noise? I was trying to get a picture of the misty water on the weir The settings were ISO 100 F22 20secs (Middle of a sunny day) ND1000 Forgive the questions I am still new to this?
  2. I shoot mostly for stock with a Nikon. I bought a Lumix DMC-ZS60 (18 mps with Leica zoom) 'travel camera' to use when I am on vacation and also for casual use as I run errands about town when I don't want to lug the Nikon. I uploaded a few photos from a recent foreign vacation and had few or no issues with Alamy. I recently uploaded a batch of nine local shots (eight shot with the Nikon and one with the Lumix) and the entire lot was rejected due to the the quality of one shot from the Lumix. I am aware of Alamy's policy of rejecting one/rejecting all (which seems unfair). The Lumix is said to not be a good low-light camera and I agree with that. When this batch was rejected Alamy did cite noise as one reason for rejection but they also cited the rejection as being taken with a "digital camera not suitable for Alamy". As a result they revoked my upload privileges for 10 days. Has anyone experienced this same rejection reason with a Lumix and does Alamy in fact have a published list of cameras they automatically accept content from?
  3. Each photo has more or less noise. It is not always easy to define the subjective boundary between acceptable and too tight noise. How do you do that? Are there any tools (except looking closely) to quantify noise? With LR or some other software maybe?
  4. Hello, I am new in Photography but have gotten heavily into it. I take photo's daily as much as possible and spend a great deal of time learning how to post process the photo's in Photoshop better and learning the in's and out's of the program. I'm left with a few questions after going through countless other photo's from good photographers. First, I notice their photo's are crystal clear and usually devoid of noise. I've tried using reduce noise to reduce the noise in my photo's, as well as using a small surface blur, and even tried using a second layer with the image on top of the first layer as overlay or screen to increase contrast. I've tried using high pass also. While those things seem to work to a minor degree (Nomatter what I put the settings to) the images don't turn out like what I see with the professionals. While they look nice, if zoomed in to max resolution you see issues. If I use reduce noise or blur to fix the noise, it becomes too blurry. I'm using a Samsung Galaxy S6 Edge to shoot photo's, using pro mode so that I have as much control as possible and even doing zoom manually to get the sharpest picture possible. I have the ISO setting at 50 or 100, sometimes 200 if it's dark. I realize shooting with a high ISO will cause noise so I keep it as low as possible and try to shoot in well lit area's. I adjust the shutter speed to allow only as much light as necessary to avoid blurry pictures, and in the settings I tell the camera to save the raw dng files so that I have more to work with post processing. I realize I need a better camera, but I don't have enough money at the moment to upgrade. I was hoping to make money with what I have so that I could buy a professional DSLR camera. So, the questions I have for you guys are: 1.) What is the best entry level camera? I don't have a lot of money to spend, but I need something better than this Smartphone I imagine. I've read the best entry level is the Nikon D3300 or D3400. 2.) How much better is an entry level DSLR over a Galaxy S6 Edge? Will the photo quality improve greatly? 3.) What kind of post processing in Photoshop do you normally do to make images look their best? Are there any good tips on making images crisp/clear and noise/artifact free? Thank you in advance for your help!
  5. I've just had another photo rejected for noise. Photo taken on a Sony Nex 5N at ISO 400. Last photo to be rejected for noise was taken on the RX100, 5N has bigger sensor. What do you think ? https://postimg.cc/image/yam9zvrl7/
  6. I've had another set of pictures rejected for Noise - and the only thing I can find that might be considered noise are black dots on the leaves of the Jak tree behind the rare and pin-sharp monkey. From picture to picture, there they are, the same black dots on the same position on the same leaves. So it's not my photo, it's nature. This isn't the first time I've had rejections for nature's imperfections, so what should I do: touch up the leaves to unrealistic smoothness?
  7. Hi, I am new to this forum, so forgive me if this question has been answered elsewhere. I would like to know if the name of an image infuences QC? For example, I have some images that I have deliberately added a lot of noise to, and changed the colours, altering the hue. If I was to upload the image, I suspect it would just fail QC, but if I changed the name to 'noisey, grainy blue hue photo of buildings', for example, would the image be more likely to pass QC? Any advice on how to get 'these types' of image through QC is also welcome! Thanks
