Photoshop :: Excessive Grain / Noise After Editing In CS5 RAW
Jul 26, 2011
I have a Canon EOS 450D and started taking photos in RAW and edited the photos afterwards with the PS RAW editing function. Often, the result on the "RAW screen" is good enough and I do not open PS CS5.
The following happened (I edited nearly 100 photos like this, but printing them was a disaster!). Image during editing in RAW:
Settings:
Setting under image in RAW:
Printing photo- a scan:
Watching the photo for the first time in PS:
What went wrong? Did I sharpen too much and if so, why did the picture still showed very nice on the "RAW" image? The size of most of the photos are more than 10 MB.
I need to generate some decent grain/noise bakground for web page of size 128x128 or similar size.
I found - Grain Generator at [URL] ...... but it does not allow setup a spicle/grain size only 1pixel. I want dirrerent and random sizes from 1x1px up to 4x4px size.
Can it be simply generated in PSP X2/X4 or some good even online generator?
I've been trying to edit concert pics I've taken and a lot of them tend to be a little grainy due to the camera settings... I realize the sample picture posted my not clearly show what I'm looking for but I can forward a sample pic.
When you import a video that has image noise into Photoshop cs6 is there a way of removing it? Is it done in the same way as what you would do in removing noise from a photograph?
I edited the project-properties to HD, according to the hints Trevor gave in this topic:
[URL]
As a work-round----Change the project properties to use 1920 x 1080 and your images will be 1920 x 1080.
Settings-Project Properties (Alt+Enter) Edit File Format ---Microsoft Avi Files Edit Avi Tab Compression to Microsoft Video 1 (there may be others you can use—Div X ??) General Tab Frame Size---User Defined to 1920 x 1080
Ok now the screen shots should all use the larger image size.
I'm having a problem with excessive pixelation when using photoshop filters and masking. I've done this process 100's of times, and now this editing technique is creating patches of pixelation. Technique wise, I am on a second layer; I've applied the diffuse glow filter; then I mask the layer; select specific areas I do not want glowed; feather the selection; and then I brush away the effect from my selection. Results wise, the feathered areas and the brushed away areas appear to have holes or patches of the background layer coming through. Usually this is a smooth transition look. Now it's patchy and overpixelated somehow. I'm getting the same affect if the picture is jpg or psd. It is also doing it with just basic curves.
how to increase the size of a picture without it getting too pixelated to identify what the image is. The problem I am having is I had to take a screenshot of a picture online and I need to identify specific wording on a small item in someones hand. I tried clicking on resize image and unchecked re-sample image but that is not working either.
I am baffled why one of the files I modify on a weekly basis (for a weekly coffee shop newsletter) seems to have grown excessively over time. It is 12 pages of 8.5 x 11 size and back in January of this year the file averaged about 12 MB. It has since grown to over 400 MB, but remains at 12 pages. It contains a good mix of text, graphics and bitmaps (all B&W) but nothing that would justify such a huge file size.
We currently use CorelDRAW 15.0.0.486, SP1.
My system is an Intel Pentium G620, 2.60 GHz with 4.00 GB of RAM on 64 Bit Windows 7 Home Premium, SP1.However, I save the file over the network to an AMD Athlon II X3 440, 3.00 GHz with 2.00 GB of RAM on 64 Bit Windows 7 Pro, SP1.
I have tried deleting pages and eliminating elements in the file but it refuses to drop below 400 MB for a saved file size.
I'm using Win 7, 64-bit on a new PC with 16-GB of RAM and plenty of power. I've been editing 40 and 50 MB DNG files for several months with no difficulty. I recently scanned over 1500 old negatives (on a Plustek 7600i) and then imported these tiffs into LR. Again, there were no problems encountered.
I was editing one of these tiff files (27.68 MB) and eventually started to remove all the dust spots and scratches. At first, all went well. However, when I got up to a few hundred of these spot removals, LR4 slowed to a crawl and eventually crashed. The slowdown and crash only occurred whenever I attempted to open this particular tiff and activate the spot removal tool. All other photos opened and edited without problems.
I then tired the same spot removal on a different tiff from my scanned bunch, and encountered the same kind of slowdown and eventual crash of LR.
i had been using autocad for almost 10 years now and i always have the newer version for my line of work.
i am having trouble with the excessive styles that shows whenever i copy and paste then the problems occur after that most often. copy paste problems, fatal errors, and my computer hangs most of the time.
I used to use the add grain feature and then I would specify the grain to have a horizontal or verticle pattern. Now, I guess there is no more add grain tool unless you use bridge. So, I tried it in bridge and adding grain works but there is no way to make it horizontal or verticle. Is there any other toold that would do this effect?
I have recently started working on a project in metric and have a weird (to me) issue when I try to plot. There are literally hundreds, of scale options in the Scale popup, most of which make no sense to me. I know that I need 1:25, or 1:100 to fit on the page I am printing to. How do I remove or filter out all of the others such as 1:100 3_1_1_1_1_1? I don't even know what that notation means.
Just loaded PS CS4 on my 64 Bit Vista machine. Although loading the Grain Surgery filters, etc into my plug-ins folder works fine, CS4 doesn't 'see" them. Visual Infinity seems to have moved on so I can't ask them. Any one else have this wonderful set and had similar problems. Grain Surgery worked fine on the same machine with CS3. Grain Surgery 2 is or was such a wonderful program.
When you've got a photo which the resolution isnt that great on, you tendt to get this grainy effect. It seems to happen mainly on dark colourslike black. When you zoom in close you can see its made up of various colours. None of which generally tend to be black. Is it possible to get all these coloured pixels roughly the same colour so that you can get a smoother finish.
Ive tried various things like the heal brush, few filters etc but nothing really seems to do the trick.
I have recently acquired an image from around 1850 that I am restoring and I was wondering if anyone had advice on this one issue. The photo has alot of grain to it in the dark areas of the photo. When I start bringing the photo back to life the grain is even more noticeable obviously. Does anyone know of a good technique to remove this kind of extreme grain?
i got an ir filter and tried my first shots with my digital camera. i set the exposure at 1/20 at 3.5. the grain is unbelievable! the camera is a fuji s700. (i use pro cameras for my regular work, but i figured this one would be good enough for ir.)
I have elements 10 and am interested in other product additional filters that can remove grain/texture from old photo. I have used noise reduction, dust and despeckle as well as gaussimer blur as it is a portrait. Still not happy with results.I have heard that there are filters specifically designed to remove grain/texture.
I have LR 4.1 when I try to add grain using either a user preset or through lightrooms grain presets (heavy, light, medium) it doesn't add the grain to the video. Is this a feature that LR can't do with video
I am using the Texture --> Grain effect to give my fonts and graphics that "chalkboard look", however the grain effect makes everything that I add the effect to White. Can I not have any color using the grain effect? For example, my font is yellow but when I add the grain effect, it turns white. Is white my only option with Grain effect?
How to achieve the "chalk" look! Grain effect seems to work the best for me (except the color issue).
I'm fairly new to using bump maps and have a question about a wood grain bump map.
I am using a bmp file in the material editor for the wood grain, along with a UVW modifier to make the grain run differently on the different pieces of the furniture. I was hoping to "enhance" the appearance of the grain on the wood, so I thought I would try a bump map by using the same bmp file and set it to 30%. While there is much more texture to the grain than wanted, I'm wondering why the vertical instances of the wood do not seem to have the map applied?
Aside from that question, is there a better way of enhancing the grain pattern without necessarily increasing the texture?
