first pics nikon 3200 coolpix

this is some learning curve!! my previous thread attracted some amazing bits of advice-thanks to all! Very much appreciated! The camera is a keeper(right Jon!?) but unfortunately my first shot had a 651MB size file in JPEG! and I have to find a way to reduce the size either in my Nikon 6 photoshop or from the beginning. I obviously did something wrong with the size issue, but the camera nailed the color and luster of my 1905 one centavo!! Anything obvious that I did wrong? Surely. Someone please tell me!

    In Photoshop, goto IMAGE and then Image Size. Self explanatory from there but if you have any more questions, PM me.
  • If your using Adobe Photoshop.
    First make a copy of the image file to work on, handy for when you screw up.
    Then under the Edit menu item there is a image size option. Click on it.
    Then set the pixel width to something like 550, the hieight should automatically adjust.
    Then OK or exit that screen.
    Now at the main screen under the File menu youshould be able to use the "Save For Web" option
    At the bottom of the screen is a info section that tells you how big the jpeg image will be. You can cancel and run the image size option
    to tweak this as needed. PCGS likes under 100k byte sized images.
    When you click OK you get a second screen, check the filename, and select the jpeg only option.
    Then save it.

    There are special jpeg options for increasing compression and decreasing compression ratios on the image, as you increase the comression ratio the image quality will start to suffer. You can decide how much you need or don't need.

    Other image programs have similar options, you should see itin there someplace off the menu bar as a option of some sort.

  • I think I just figured something out. My image mode was 2048x1536 pixels. Should I have used the "posting to the web" recommended 640x480? Will this change the quality of the picture or just reduce the incredible size?

    Reduce it's size. 450-500x450-500 is pretty big for threads.
    You lose some slight detail when you use different .jpg compression levels.

    In Photoshop, I like to use the Save for Web command. You can adjust size and jpg compression to make the file exactly the size and number of Kbytes you want. Also, at the bottom of the page there's a little Internet Explorer icon. CLick on it, and it will preview the pic in an IE window for you.

    I would imagine there must be some sort of resolution settings in the camara setup.

    Perhaps change the settings from High Res to normal or something like that.
  • ttt, so if I reshoot the coin with the 640x480 mode it looks like I can get under 50MB, right?

    Shoot full size and then reduce it in photoshop--the quality will be much better.

    And I think you mean kb, not mb... 651mb would just barely fit on a CD.

    Cropping works wonders to get the size down also.

  • I think i take all my pix with the coolpix 775 set to vga and basic.
    check your manual.
    at those settings they are always smaller than 50kb
    took some pix of a watch last nite,set to vga and fine that were 700 kb
    lighting is a bugger on coins,worse on slabs !

  • Just keep playing with it and you will find a happy trade off between the size of the file and how big you would like the picture to be on screen.

    The pictures on my web page had to be made small enough that I could fit them all into a 10MB limitation for the whole site. Since I have 108 coins on the page that is 216 pictures (for obverse and reverse). It doesn't much to fill up 10MB with 216 pictures.

    Good luck and have fun with it.
  • Hi,

    In Photoshop... you can use the "save as" choice, save it as a JEPG... then rename the photo and the optimize will automatically pop up, you can see how the photo will look at different save levels in the preview.... usually an 800x600 image saved at level 8 will be 100k or less.

    You'll aslo still have the original saved if you have to go back and do it again.

    Anthony
