    <p>A few years ago, I wanted to check the accuracy of the Walgreens printer, so I employed a little trickery that may help you here. </p>

    <p>Take a photograph of anything, but put a grey card in it. Make the card prominent, over half the image. In your editing software, pull up the image and use the grey card to color balance it. Then print it up. Tape the picture to a piece of cardboard or something to make it stiff. </p>

    <p>Now lay the picture of the grey card up against something to hold it up, and set the actual grey card next to it. Then take a picture of both of them together. Pull up this second image in your editing software. Use the portion of the image representing the actual card to color balance the image, then check the color balance of the portion of image representing the photograph. ( sound confusing? ) So if the photograph part contains too little red, you must add red. If the photograph part contains too much blue, you must remove some blue. </p>

    <p>Then make adjustments to your printer and repeat the exercise. When both parts of your second photograph have the same color balance, your printer is printing correctly. </p>

  2. <p>It is also possible there was a development error. I had that happen to me with slide film. Portra is a very good film that rarely fails. <br>

    There is a trick that usually works when shooting in unusual light. Snap a pic of a grey card using a flash or mid-day sun. Then use the software ( I use VueScan ) to correct the color using that shot. The other shots in orange sunlight should look nice and warm, even if the development or film is off color. </p>

  3. <p>I have done a cheated HDR with 35mm film. I take an exposure, which will have a range greater than a digital image, scan it, and make 2 images of different brightnesses. Then I make one a layer over the other and use the eraser tool to make certain areas lighter or darker. I guess we can call it HAHDR, ( half - a** high dynamic range ). </p>
  4. <p>I am not a crop artist. To me, there is nothing wrong with environmental portraiture. Showing a subject in his environment can be very powerful. </p>

    <p>Though I have never seen one, I have heard of this lens with a mirror in the side that focuses sideways. You point your camera in one direction, you are actually focusing off the the side. This would be perfect if you want candid shots. :-) </p>
