    Digital Processing is Very TEDIOUS! You Agree?

    <p>once again, lightroom. It is 100% focused on managing your photographs. You can easily save multiple edits, e.g. croppings, color saturation, curves, etc. all from two screens, while managing your photos in the structure you like. You can copy settings from one photo to as many as you like that look about the same, saving loads of time. You can set up a quick workflow when you get used to it.<br /> PLus there are modules for generating a web page for your photos, creating pdf slideshows, and printing your photos.<br /> Photoshop is gee whiz feature laden, but you don't need that when loading and evaluating hundreds of photos at a time.<br>

    I used to do black and white film and print processing and it could take three or four tries to get it just the way you wanted it with dodging and burning and overall exposure. Now it takes a minute and you don't get chemicals all over the place.</p>

    Lightroom "1:1"

    in The Digital Darkroom: Process, Technique & Printing

    Posted

    <p>Roger and Ellis, I wouldn't (and certainly couldn't!) print a picture that size. I haven't got that much wall space left in my apartment. But that is what the 1:1 setting extrapolates to at the current resolution.<br>

    The 81 ppi figure is just the division of the pixels in the image by the apparent 4:1 size increase that the 1:1 setting gives me.This is a Lightroom feature, not a function of the monitor. If I divide the rated resolution of 1280x1024 and divide the 1280 by 14.75" width, I get 87. I tried other resolutions and ended up with different magnifications from "fit" to "1:1". I couldn't find any resolution figure other than the 1280x1024 on the ViewSonic website's specs for the monitor. So apparently the ratio is a function of the screen resolution, since as the resolution goes down, the ratio goes up.<br>

    I ran the checks at http://brighamrad.harvard.edu/research/topics/vispercep/tutorial.html and the resolution of lines and gradations are more than satisfactory at the max resolution.<br>

    Thanks for responding. Ray</p>

     

    Lightroom "1:1"

    in The Digital Darkroom: Process, Technique & Printing

    Posted

    <p>I have a 19" ViewSonic monitor set to Srgb and am using Lightroom 2.2.<br>

    If I knock off the side panels in Develop mode with the zoom on Fit, an uncropped picture comes in at 12" by 8" on the screen. If I set it to 1:1 zoom, it comes out 4 times larger, the equivalent of 48" by 32".Since I had my Pentax K10D camera repaired, the resolution is acceptable on screen at that size.<br>

    But what are they basing that "1" on? The rated pixels for an uncropped shot are 3872x2592. If I divide the 3872 by 48, I get about 81 pixels per inch. This seems rather low.<br>

    Any information about this would be helpful. Thanks, Ray</p>

    Stupid K10D question

    in Pentax

    Posted

    <p>I have the menu option turned on that when I hit the EV button, the top LCD screen lights up, useful on gray days or at night. But is there a way to turn it off once it's on short of turning the camera off and on again?<br>

    <br /> Thanks, Ray</p>

    EXIF problem.. Lightroom 2.2?

    in PhotoNet Site Help

    Posted

    <p>I'm not sure if it's a coincidence, but I haven't put up any pictures this week till today. Previously the EXIF data was working consistently fpr weels when I did multiple pictures.Today I tried a single picture and there is no EXIF info in Details.<br>

    Complicating matters is that I upgraded to Lightroom 2.2 in the meantime, so maybe that is the problem? I look at the photo on XNView and the information shows up in its viewer there, so it is going out with the picture. I'll try adding the single photo through the multiple feature and see if it works.</p>

    A walk through Central Park

    <p>We definitely have different views of the same place. You seem to be standing back as an outside observer, getting the big picture of the architecture and landscaping, where I tend to get into the details and the people side of the park. Using a long lens though, still not up to putting cameras close to peoples' faces (generally not a good idea in NYC.)<br>

    Also all with a K10D with the 18-55 or the Sigma 70-300.</p>

    I was right about my K10D

    <p>I had sent in a number of pictures a few months ago that I felt were not as sharp as they should be. Replies suggested that it was me moving the camera. However, I found it to be inconsistent, sometimes worse than others. I tried consciously being as still as possible, but no real difference. Even at 1/800 with SR on, it was inconsistent.<br>

    I looked into that program that the Russian adapted for 1.3 firmware that adjusted the focus parameters throgh the USB cable but was wary about it because messing up the firmware can be problematic to say the least. So I told Pentax about it when I sent it in for adjustment. It took two weeks and came back today.<br>

    They said they set all functions to factory specifications, and "replacement or adjustment of electronic autofocus circuit including focus motore and encoder, CCD focus device. Computer adjust to factory settings."<br>

    There's a world of difference. i can read type on a stock certificate 15 feet away at 20x. Before it would have fuzzed out at 8x or so.<br>

    So if you're not happy with the focusing, it might be worth checking out. And the best part was, it got delivered on Christmas Eve (without the lens cap, but let's not quibble today...)<br>

    Sigma made Pentax FA & DA lens(es) Observation (s)

    <p>http://www.sigmaphoto.com/lenses/lenses_all_details.asp?id=3349&navigator=3 says the MSRP is $34,000. We all pay MSRP, right? The Going Out of Business Store in Times Square where I bought mine said Sigma never discounts. But it does include a 2x teleconverter giving 400-1000 at f5.6. And it's big enough to wear as a hat if it's raining.<br>

    I like the 70-300 F4-5.6(lower cost one) and the 24-60 f/2.8 Sigma lenses a lot. Great quality for the price. My 10-20 seemed to have a focusing problem that matched just what one of the Amazon reviews said.It wouldn't change focus as distance changed, and often the lens said it was focusing at say 10 or 15 meters when I was taking things at infinity. Will reorder another one though when I get my camera back from pentax, since it was probably just a bad unit. The pictures looked very sharp when it focused right.</p>

     

    A very minor nit

    in PhotoNet Site Help

    Posted

    <p>When I click on the space between the scroll bar pointers in the photo crique forum, it often jumps two screens worth of pictures, snap snap (not one continuous motion) like it was reading two clicks. I don't seem to be having this problem on other sites with long pages. This is even if I tap it with the lightest touch. This has been with two different trackball devices.<br>

    Thanks, Ray</p>

    Why SLR?

    in Casual Photo Conversations

    Posted

    <p>A DSLR is a point and shoot as well. Click P or green square, point and shoot.<br>

    I bought a dslr because I've been using slrs for 35 years. And I want the option of more lenses, including lenses by other vendors.<br>

    They probably will disappear in a while, the R meaning reflex, which means mirror. Mirrors and optical viewfinders will probably disappear from lower end DSL® cameras in five years or so for cost reasons.</p>
