![]() ![]() Irfanview requests the location of the destination folder for the out-putted images, so I asked it to place the processed images in the 002 Batch directory. I then clicked on 'advanced' and set the pixel dimensions I wanted (1200 x 900) and the 100 dpi resolution. In Irfanview, I opened the first image in the 125-strong list, then clicked on the 'batch' option. In this instance, the earlier 2.47Mb size has reduced to 724kb.Ħ) The 100dpi resolution means that image quality is at its absolute maximum for viewing on a computer screen, but the reduced size means that three pictures can be uploaded in the same time and same 'space' originally taken up by just one.ħ) As to re-sizing / re-sampling, I always use the superb freeware, Irfanview, because it's daft to attempt to undertake a job like this on a picture-by-picture basis. I've also decided to increase the dpi from 72 to 100, because the lower figure isn't mandatory any longer where computer monitors are concerned.ĥ) The effect of such changes is to create a revised and resampled image that is 1200 pixels wide by 900 pixels high (which is why I stuck with the 100dpi figure, because it makes pixel dimensions easy to remember). ![]() This is a proportional reduction the 4:3 aspect ratio remains intact. At a dpi resolution of 72, however, the pixel size is well over 20M.ģ) Whilst this image size is perfect for post-processing in Photoshop or any other image editor, it's anything but suitable for uploading: the time involved will be lengthy, and the demands made on TA's own equipment at the receiving end, excessive.Ĥ) After experimenting with various measurements, I've opted to drop the image size from 42.7 inches to 12 inches wide, and from 32 inches to 9 inches high. Typically, the apparent file size of such an image is 2.47Mb. This means that each out-of-camera image is 3072 x 2304 pixels the image size is 42.7 inches wide by 32 inches high. (The other directory was 002 Batch.)Ģ) All pictures were shot at the camera's 'highest quality' setting. The images all went to a folder (named 'Lakes', in this instance) and the first of two directories: 001 Originals. The number of images unloaded was 325, from which 200 have been deleted once I'd viewed them on-screen. It's a three-year-old pocketable Panasonic Lumix DMC TZ-3, point-and-shoot, nothing extraordinary but, yes, it can take some great pictures thanks to an excellent lens. If it's of any help at all, here's what I've done today in regard to our recent stay in The Lake District, UK.ġ) First off, I unloaded the images from the camera onto the computer. Hi Country Wife - oh, and anyone else who might be browsing this thread. I now seem to have answered my own questions. But as you say, anything higher than that is a waste.Īs to image dimensions, and in view of the 5Mb file size maximum, it's probably going to be the case that a landscape image at 90dpi at a file size of 2.5Mb (half the maximum) is perhaps the best - i.e., the uploaded file size dictates the image dimensions, rather than t'other way around.Įr, um. I think that's the explanation!Īs to screen res, yes, you're correct, 72dpi certainly was the maximum resolution capable of being handled by CRT and early generation LCD monitors but things have moved on a bit, so I'm thinking 90dpi might be more appropriate nowadays. I'm guessing that what TA is trying to say is, don't post images which can be viewed only by someone turning her / his head to see 'em properly. The "sideways" oddity occurs in the Help Center photo management text, where it says TA is unable to handle this kind of image. Wow, talk about supersonic speed! Many, many thanks for that instant reply - very much appreciated. I suppose another way to refer to it is an image that has been rotated 90 degrees so that the photo looks like it is laying on its side. > I could not find the reference to sideways - but if they are telling you not to do it it means to upload an image where the top of the image is aligned to one of the sides of the photos and not on the top. > I have to leave that one for the others.ģ) Just what is meant by TA's reference to "sideways"? ![]() That is what i learned 10 years ago when editing images for a website, so I suppose things may have changed with better monitors - but this is my understandingĢ) What are the preferred dimensions of an image upload. > My understanding is 72 dpi is about the max a monitor can display, so anything more is just increasing the size of the file with no visual improvement except when printing. I'm no expert, but I'll post what i know and I'm sure others will add to it:ġ) What is the preferred resolution of an image upload, for example: not less than 72 dpi / not more than 100 dpi? ![]()
