Re: What benefit .png over .jpg?
Film vs Digital is a mixed bag. Film has more dpi resolution -- more MP. Digital is a lot more flexible -- you can go from ISO 200 to ISO 16,000 and back without thinking twice. With a 35mm camera, you shot the roll of film, and if you needed a low-light shot and you had ISO 50, you were hosed. :) Now that cameras like the D600 are starting to inch in on that territory ( http://kenrockwell.com/nikon/d600.htm), that may change. But film is not going away. Photography is an artistic medium, and as such, it's subjective. Meaning, people will always have personal opinions based on their own preferences, and often having little to do with reality, other than they find it fun. (I say this as someone who owns a very-obsolete D40, and wouldn't mind tinkering with a film one.) People are still using pinhole cameras. Why? Because it's fun. Note also that the professional photographer I linked to loves that camera, because it's full-frame (a full 35mm-sized sensor, rather than a smaller sensor with the same aspect ratio), but he still shoots it in 6MP mode. MP are great if you're printing things that are flippin' huge and are meant to be seen up-close. Or if you're doing work that is usually done by a large-format camera -- the kind Ansel Adams used. For 99.999% of what people use cameras for, 6MP is just fine. The same website had an article for the D60 that came out and made my D40 'obsolete.' The only thing you got was 10 MP instead of 6, and a slower sensor (100 ISO at the bottom instead of 200). But hey, it sold! I'm guilty of falling for this fallacy to a point. I typically shoot in RAW format. But whenever I have to send a picture to a friend, it usually goes straight to jpeg-basic. And they're thrilled to pieces with it. I'm just indulging in my own vices by keeping things in the 'nice' image format for myself. But, like Ken said. Best thing to do, if you are a shutterbug, is to not fret over the stats, grab a camera (any camera), go out, and shoot. You will become a much better photographer by doing that than worrying about camera specs. /tangent Adam On 4 October 2012 21:47, Joseph Sinclair plug-discuss...@stcaz.net wrote: PNG addressed two problems with GIF. 1) GIF is an 8-bit format with an indexed color palette. It's possible to do 24-bit color by overlaying a red, green, and blue image mask, but it's not ideal. PNG is true 24-bit color with better compression. 2) GIF was, for a time, covered by patents on it's LZW compression, held by UNISYS that limited it's use in many situations. Those patents are expired in 2003/2004 and there is no longer any patent encumbrance for GIF or LZW compression. GIF has built-in support for animation, which PNG does not. MNG provides animation of PNG images, and APNG provides a more recent alternative animation mechanism for PNG images that's easier to create but less efficient in compression. I definitely agree that resolution matters most when printing. A 1080p screen displays a 2 megapixel image, so more than that is not usually helpful for onscreen display (4 megapixel is fine for the rare 4K display). I don't worry much about file size with 32G thumb drives and SD cards now common. I figure 4,000 images (8 megapixel PNG) on a single thumb drive or SD card is more than enough storage for away-from-home use, and at home 2TB backup drives are pretty cheap these days. BTW, typically 48 megapixel at 32-bit color (24 bits plus 8 bit alpha) is considered the minimum to match 35mm film. The biggest remaining problem in digital is dynamic range (quality film is usually 3-5 stops, digital struggles to get 2). The resolution difference isn't considered a big deal in most print publications (AZ highways is an exception, for good reason), so almost all professional photography is currently digital capture and workflow.

A few years ago I saw an article in Arizona Highways showing why they don't accept pictures in digital format. The had two photos of the same tree. One taken on film and one taken with a digital camera at several megapixels. Both looked equally as good. Then they blew up a small portion of the image. The film version looked great. The digital version was obviously of poor quality. The article went on to say what resolution was needed to equal the quality of 35mm film. I forget the number, but it was way higher than what was commonly available at the time. Someone please correct me if I'm wrong, but wasn't png developed in part because of concerns about software patents relating to the gif format? On 10/4/2012 17:16, j...@actionline.com wrote: Thanks.

OT USB to PS/2 adapters
I have a relatively new (1yr) PC without PS/2 keyboard mouse connectors. I've accumulated 4 USB to PS/2 adapters. Three are just 6 cables with a USB male on one end and a PS/2 female on the other. The fourth is similar, but has a large oval-ish thing in the middle of the cable. My MS ergonomic keyboard has a PS/2 connector and will not work when connected using one of the three plain adapters, but will with the fourth. I'd like to understand a) why, and b) where to buy a couple more of the adapters that do work (for another project).

Re: gimp save formats
From: Michael Havens bmi...@gmail.com I'm delving into GIMP. What is the best save format? JPG, GIF, etc... Gimp's native format, XCF, saves all the layers, masks, channels, and subsidiary information. If you want to stop partway through editing a file and return to editing it later, then save it as XCF. Most non-Linux image viewers can't read XCF, though, and web browsers can't read XCF either. You'll probably save the final version of your image as JPEG, PNG, or TIFF. TIFF is (well, should be) future-proof, supports multiple pages[0], can store data losslessly or lossily[1], and has always had support for resolution tags. Its many useful features should've made it the image format of choice, but Unisys caused a great deal of stupid hassle and basically killed it for wide-spectrum use. People discussed JPEG vs. PNG vs. GIF and when to use each earlier on this mailing list. Refer to that for the full scoop. Short form: Photos where lossy is OK = JPEG. Line art or logos or things where lossy is not OK = PNG. Animation required = GIF, since MNG is not as widely supported. (Black-and-white, maximum compression required = TIFF Group4, but you probably don't care about that special use case.) [0] Some things don't handle multi-page TIFF very well, though. [1] JPEG-TIFF is possible, but almost nothing supports it. -- Matt G / Dances With Crows The Crow202 Blog: http://crow202.org/wordpress/ There is no Darkness in Eternity/But only Light too dim for us to see --- PLUG-discuss mailing list - PLUG-discuss@lists.plug.phoenix.az.us To subscribe, unsubscribe, or to change your mail settings: http://lists.PLUG.phoenix.az.us/mailman/listinfo/plug-discuss
Re: gimp save formats
The recent thread on png vs jpg might provide some helpful information. I'll try to give a brief answer. Jpeg throws away much of the information contained in the picture. If you just want to look at the picture but don't want to edit it, jpeg should be ok. Png doesn't throw away any of the data, but compresses it so none of the data is lost. This makes for a larger file, but a better choice if you want to maintain quality after editing the file. Gif is an old format dating back to 1987. It's 8 bits per pixel so you only get 256 possible colors. Also anything I've read about tiff says it's preferred by professionals especially when they're going to edit the result. A tiff image can be uncompressed, or compressed using either lossy or lossless options. I would suggest saving anything you're editing as an uncompressed tiff file while you're working on it. I have a 10 megapixel camera that saves pictures as jpg files. I've taken several pictures to walmart to have them printed, and they look fine. No doubt by the time the weekend's over, you'll get some useful information. bye Derek On 10/5/2012 16:08, Michael Havens wrote: I'm delving into GIMP. What is the best save format?

Re: OT USB to PS/2 adapters
A corollary to RTFM is Look at the Stupid Device. It had Radio Shack molded into the front and even had a part #. on the back. Duh! I was setting up my wife's new box and of course had the same issue there, so I got on my horse got myself over to Radio Shack. The durn thing cost $20, but now everything works! The USB 1 vs USB 2 makes sense. I'm pretty sure that I'd successfully used those simple adapters sometime in the past, but everything's USB 2 now, going to 3. Mark Jarvis Lisa Kachold wrote: Hi Guys!

Re: O.T. Hostgator Registrar
Thank you for your feedback Lisa! I have some domains registered at Godaddy, and some in a WWD (godaddy reseller) account. Godaddy has been reliable. I host my business website there. I also have a HostGator reseller account. Today I wanted to convert one of my business email accounts from pop3 to imap. I already have an add on email account so I can store more email. I had to pay even more for imap. I understand why Godaddy does business the way they do, however I'm growing tired of them nickle and dimeing me every time I want to do something. I want to make life simple so I'm thinking of consolidating everything into my reseller account and moving my domains to HostGator.

Re: O.T. Hostgator Registrar
I've looked at going outside gd for years, but most providers do tend to nickle and dime everyone to death. I've wanted to just get dedicated hosts, but hard to justify $200/mo per box to *play* with. Virtual just isn't that attractive as at the end of the day, there is resource contention going to occur to give me any level of warm fuzzies. I'd probably be the bastard too that kills the box. Sadly the only reason I stay GD them to now is a) I prepaid for many years with many domains, and b) they have my old employee status screwed up stuck in the system to the effect I get some free services, which is kinda dandy by me so far. Just the general attitude of the company and particularly certain people I know far too well there from old times make me overdue to migrate off them still, and I have been shopping to do so. Good external solutions are elusive that don't end up costing me way more for what I get today from hosting my own servers at home. I know pretty well infrastructure, and good ones cost more than my house budget to build, but finding reasonably affordable (per joe schmoe) hosting can still surprisingly be a challenge. Especially when it largely amounts to a playground I make no money off of what so ever. Even shopping minecraft hosting providers cost is expensive when it comes down to memory usage needed for extensive worlds. Shared hosting is useful if you're just doing websites, but vps/dedicated I'd think should be more cost-reasonable by now. GD doesn't even offer ubuntu still as a vps, so that's an easy out. I too am a bit curious who/what/if others use for shared/dedicated hosting plus affordable lab and casual use outside their house. I have most of my lab running off my own servers (dated dell 1850's) at home with esx and a lot of instances that I cannot reasonably replace as a cloud and a non-corporate invested profit center. -mb On 10/05/2012 09:19 PM, keith smith wrote: Thank you for your feedback Lisa!
