  1. Congratulations to romania and bulgaria! Sure there will be short term and long term affects, but I'm sure everyone hopes that in the long term this will be a positive thing. Although there is no euro yet, I believe there are lots of other changes involved with becoming part of europe, things like being subject to european laws, ease of movement of people, jobs, goods etc across the borders, and huge confidence boost for europeans to invest within the new entrants, because they know there is far reduced beaurocracy between european countries. One effect of this has been europeans
  2. First line of defence is a regular scan with spybot search & destroy, then adaware. If you get something and these aren't picking it up, I also recommend the free online scan at http://www.trendmicro.com . It takes ages but manages to catch all kinds of things that other scanners miss. 'HijackThis' is also another program that's very useful but only if you know what you are doing. But the single most important thing for avoiding malware is to install firefox. Also, once you have firefox installed, load up IE, and set security settings to maximum, close it, then never touch it again
  3. 134 accepted, 3 rejected so around 98%. Had one rejected for overly simple vector, one was a joke pic, and much as I hate to admit it, I even had one rejected for noise or artefacts. So let me say when people complain of outrageous rejections for noise, I FEEL YOUR PAIN.
  4. I'd have thought you'd have needed a neutral third party as a witness ... that's the idea of a witness. I usually use a neighbour. IANAL, and you'd have to consult a lawyer for reliable advice, but this is my understanding: Think of it like this, a model release is a document showing that the model has consented to use of their image. A witness is there to provide a certain amount of protection against photographers forging releases (being a third party), and models making counter claims that a release is forged (when it is in fact genuine). A photographer signing as photographer A
  5. On a CRT, imo the most important thing about refresh rates is that low ones will give you headaches (60-75 hz or so). If you can get 100 hz or higher you'll appreciate it. On an LCD, refresh rate is less important as the screen holds it's colour more over the refresh, so you don't get flicker (which is what causes the headaches). But these days, I'd really go for an LCD, it's a no brainer, CRTs are soooo last century (a lot of places don't even sell CRTs anymore). I think you can pick up decent 19 inch ones for around 200 squid, I have a 19 inch iiyama prolite, it's fantastic. Have a n
  6. I can't see any noise .. but wouldn't say that this particular area of the photo is in focus (I'm assuming this is a 100% crop).
  7. Nope. Correct. Not in principle (providing camera manafacturers refrain from any hard baking of colour balance into their RAW files). Bear in mind however that setting e.g. a white card white balance can be easier if you do it at the shoot. In addition auto-white balance on most cameras may not be available in the same way at post processing time (although personally I only use auto white balance for snapshots now, it's so all over the place). Correct. Indeed, that's the whole idea behind RAW. Bottom line is, everyone shoots RAW, it's just a question of whether
  8. It's quite confusing, because some articles seem to quote a very high quantum efficiency for ccds: http://micro.magnet.fsu.edu/primer/digitalimaging/concepts/quantumefficiency.html And above they define quantum efficiency as: However susan's article suggests that several successful 'captures' of photons may be necessary for the registering of a unit of light on current ccds (if the new chip is really '2,000 times more sensitive to light'), not sure which articles to believe really (as you never know what is marketing hype). Maybe there is a stage after the quantum efficiency whe
  9. Add my agreement to fuzzbass here. Interesting point from davidcrehner about increasing the base sensitivity of a sensor - however, ultimately the limit is physics, unless your talking star trek technology lol. As far as I remember from my physics lessons(!) and experiments with programming radiosity, photons are particles (with wave like properties), and there is a lot of randomness involved as to whether a photon will be emitted in any particular direction at any moment by a light source. As you move further from a light source the amount of photons hitting a given surface area (
  10. muchliang: If you are able to post scaled down versions and 100% crops (a pixel for pixel crop of the original) of your images in here, we'll do our best to help you learn to identify any technical problems with your images, and how to avoid them. It's difficult at first I'll admit, but once your eyes know what to look for, it becomes quite easy to get past the issues of noise and artefacts. It's would be a very good idea to post your next 10 up for critique before you submit them, because usually other members will be able to pick up on any problems the reviewers might spot. Als
  11. Agree this kind of thing seems to be the best way. After a bit of experimentation I now do neat image on a separate top layer (everything is affected), create a layer mask for this layer, invert the mask (nothing is affected), then paint into the mask areas where I want neat image to affect (just noise, nothing else). This has the benefit of being easily reversible for any area of the image.
  12. If you want to see how to really get rid of noise ... have a look at how the space telescope type things are made to work. http://en.wikipedia.org/wiki/Astrophotography You have 2 main types of noise .. fixed pattern noise, and random noise. To remove fixed pattern type noise you can do things like take a series of similar 'null exposures' (at a similar shutter speed and conditions), then subtract the average noise from your photo. Afaik this is what noise reduction does on nikon cameras when you take a long exposure and it says 'job noise reduction' (this is incidently very different
  13. Snap, I use photobox to get my prints too ... the image only seems to show when I'm logged in though, so you probably need to host it somewhere else.
  14. A beautiful scene indeed with the mountain and the giant ducks. I had this one yesterday:
  15. This will be the kind of thing they were referring to, I'd imagine:
