    Can you help me clarify something

    in The Digital Darkroom: Process, Technique & Printing

    Posted

    Whatever. Being that we were discussing USM which is part of Photoshop, an Adobe product, I guess I'm out of line using "Adobe speak" since this IS an Adobe program? I think not. Different definitions, absolutely. I didn't write Photoshop nor USM, I simply pointed out how it was defined by Adobe. What is "outside my world", in this instance Photoshop , is irrelevant. It's not intrupation, it's fact. Sorry if my use of the word "nonsense" ruffled some feathers. It wasn't intended to. Voice inflection doesn't come across in text :-)

     

    BTW, I found your comment about how "image processing is my area of research (as in algorithms, not dinking around with consumer software)" equaly dismissive. I guess we're even. I included my credentials, which you equally dismissed, just to show that I was qualified to comment on the " Adobe Speak" nothing more :-)

    Excuse me Karl, but I was on the development team of Photoshop v 1.x. I have been on the Alpha/beta team of every version since .087a I know very well what the definition is. The calculations are done across the entire image. The radius simply tells how far from a particular pixel that particular pixel will effect other pixels. It still looks at every pixel in the image to see if it will create an effect or not.

    This USM is local is absolute nonsense, the fiter applies to the entire image, making it global, unless a selection is active. It applies to the entire image based on the values entered into the filter dialg box but the entire image is calculated across. Even if masked it still applied to the entire image, making it global, the mask simply hides the effect in a given layer, but the effect was global none the less.

    resolution limits

    Actually, in this case I believe the default 72ppi came from the early mono-sync monitors which at the time were generally built at or about 72ppi. But Kelly is absolutely right that it was a way of equating monitor (pixels) to print (points). Now with multisync displays it is not unusual to see 108ppi and 116ppi or even higher resolutions. This may be were some of the confusion about screen resolution comes from. To measure the ppi of a particular monitor you could measure the physical screen image area (not including the border) and divide by the current display resolution (which on a Mac is displayed in the "Displays" control panel) and that would yield the approximate resolution (ppi) of your monitor at it's current setting. On a Mac, your video card also effects the possible resolution setting for your monitor, your video card may not support all of the resolutions that your monitor can and vice versa.

    Computer Choking on CS3 with large files: Do I need a faster computer or can the one I have be tweaked to run faster?

    FWI, Photoshop CS3 on both platforms can only address 3GB of RAM. However, if you have more than that you may not be getting the most efficient use of the 3GB that Photoshop sees. Ex: If you have 3GB of RAM in your computer your system will use some of it, thus the Photoshop "Memory and Image Cache" Prefs allows you to allocate how much of the total RAM you would like to use. As a general rule I never go over 75% of avaliable RAM. If however, you have more than 3GB of RAM (say 4GB) although Photoshop can only address the first 3GB your system can still use what Photoshop can't. In this case you could set your Prefs to 100% of available RAM as there is still another 1GB for the system to use that Photoshop can't see. Further, as other's have pointed out, your scratch disc is only 1/100th (or less) the speed of your RAM so you need the fastest and biggest HD you can find. Empty is better as the read/write head(s) won't have to lift over fragmented files.

    Mac Memory Requirements for Photoshop

    in The Digital Darkroom: Process, Technique & Printing

    Kelly, I'm on the opposite side our your layout. I have about two dozen machines all but 4 are Macs. Running CS2 on an Intel Mac has proven to be grueling, but CS3 on the exact same machine (CS3 is all new native code) has proven to be easily 3 times faster on most processes. All 3 of the machines that we upgraded to Vista got bricked, but the new Dell machine we bought with Vista has had very few problems.

     

    Did you happen to see the article a few weeks ago about Rambus' new 1TB memory chip that is 5 times faster than the PC2-5300 ram (the real bottle neck in computing)? Once a 64 bit version Photoshop is released (can't tell due to N.D.A.) we could see some smokin' machines that could work exclusively in RAM (2TB can be addressed in 64 bit). Neat stuff!

    Try resetting your brushes. You can do this by selecting the Brush Tool in the tool bar to make it active (or press "B" for brush on your keyboard). At the far left hand side of your Option bar (at the top of your screen) there is a tool preset. Right mouse click (Mac users Control-Click) on the TRIANGLE (not the brush icon!) and you will get a pop-down menu asking if you would like to reset the tool or all tools.

    P.S. If you are using a round standard brush, "["+shift (to the right of the "P" key on your keyboard) makes your brush softer, "]" +shift makes your brush harder.

    I need fonts please

    Anesh Pather,

     

    Upgrading Photoshop should have no effect on your fonts as they are a system function not Photoshop. None-the-less, www.dafont.com has a huge library of free and nearly free fonts (yea, I know they are really typefaces not fonts but thats what the industry calls them) and another cool tool that lets you choose subtistute fonts that are very close to the same shape.

     

    Hey Will,

     

    I think you mean www.dafont.com (singular?) Great sight BTW, I also like Indentifont.com

    Layers are the building blocks of Photoshop eg: layers are artwork stacked on top of each other. If you are looking to build images from multiple sources, layers are a must. Deke has several chapters dedicated to layers and compositing as well as the DVD that comes with the book. Being an effects photographer for nearly 30 years, I have always subscribed to doing as much possible with "good imaging" from the start but some times you have no choice but to edit on the computer. When it comes to bad photography, "You can't polish a turd". Nothing, not even Photoshop will fix bad composition.
