  1. <p>PPI is pixels per inch. There is no relationship between PPI and the 4k resolution.<br>

    PPI is meaningless in terms of projectors, only the actual number of pixels matters.<br>

    It is just a number that tells a printer how big to make an image on a printed page.<br>

    Your image will always be 4096 px wide, so if you project it 40in wide your PPI is 4096/40 ie 102.4 PPI.<br>

    If you project it 100 in wide your PPI will be 40.96.<br>

    If you are talking about what value of PPI to set when preparing the image, it doesn't matter. Any value will do, the projector ignores it.<br>

    However if you want to PRINT it out to be say 12 in wide, then you set the PPI to 4096/12 (ie 341PPI) and the printer will print it out at the right size.<br>

    Hope that helps.</p>

  2. <p>Visit www.wnsoft.com and take a look at pictures2exe (assuming you are a Windows user).<br /> It allows you to do exactly what you want, and there is a trial download.<br /> I've been using it for several years and can recommend it.<br /> There is another similar program called ProShow Gold. I tried it some years ago but preferred pictures2exe.<br>

    Neither is free, but they are not expensive.</p>

  3. <p>I also recommend what Danny said.<br>

    I copy quite a few prints this way and the results are excellent.<br>

    My suggestions:<br>

    Place the painting on a low coffee table in front of a North facing window (assuming you're in the northern hemisphere) and use a tripod.<br>

    Place a small mirror on the centre of the painting and adjust the angle of the camera to align the reflection of its lens to the exact centre of the frame. Zooming in helps. This ensures perfect alignment and avoids distortions.<br>

    Remove the mirror and move the painting to fit the frame and get it parallel to the frame edges.<br>

    Try to use a mid-range zoom setting as most lenses will have some distortion at the wide end.<br>

    Experiment with exposure and white balance settings. I find that Auto white balance is usually OK unless the paintings have large areas of a strong colour.<br>

    If you can shoot in RAW it may be easier to adjust the white balance in processing.</p>

     

  4. <p>Andrew, the CS2 download is totally legitimate. I've done it, although I am a registered user of CS2.<br>

    I discovered it when I wanted to move my CS2 to another computer and when I tried to Activate the new installation, a message appeared that the Activation Server was unavailable, and hence I couldn't run my CS2.<br>

    By searching with Google and on the Adobe site I then discovered that Adobe had closed Activation Server for CS2 products, but a free download was available which didn't need Activation. I needed my Adobe ID to access the download.<br>

    So I downloaded it and all is well. It installs without requiring Activation.</p>

  5. <p>A couple of points.<br>

    If you haven't already done it, update the Camera Raw for CS2 to version 3.7, which is the last version that works with CS2.<br>

    When you use the DNG converter be careful to select output compatible with ACR 2.4 or later in the Preferences settings.<br>

    Lightroom 4 doesn't run under Windows XP or earlier versions. You need Vista, 7 or 8.</p>

    <p>Hope that helps</p>

  6. <p>Whatever make you choose I would suggest a model with XGA resolution (1024x768 px) rather than a wide screen version as I assume many of your images will be in portrait format.<br>

    Also make sure the projector has an sRGB mode to ensure the best tonal range.<br>

    Benq and Optoma are two makes with good reputations for photographic applications.</p>

  7. <p>I'm not familiar with the 3800, but on the 1270 you can run a nozzle check directly from the printer without it being connected to a PC.<br>

    With the printer off you press and hold the Paper Feed button and press the Power On button.<br>

    Details are in the handbook.<br>

    If the 3800 has a similar option it would tell you whether the problem is the printer or the PC/driver/usb.</p>
