I've noticed large sized (space) photos like this one Tom Mullin posted of a THF train.
Notice how large the photo is in comparison to the print. How are photos posted this way? Often I try to post a photo and must reduce it so much that it loses the clarity needed, or else I must crop it down so much that it must be "chopped" in half and posted in two pieces.
There seems to be no rhyme or reason to some of the pics I post "making it" and others (same pixels) being too large.
Any help appreciated. And I'm not very computer savvy.....
Rob, I'm with ya! I don't wanna come across as being a "whiner" or whatever, I certainly appreciate this forum to the "nth" degree. But I agree, it's often hard to post pics under the 200kb limit. I thought I had a real nice shot of my '12 Roadster pickup to post the other day after a great outing, but couldn't. Not trying to show off really, just trying to "show it". Maybe someday whoever controls the forum specs will be able to increase the size to at least say 300kb.
Like you, I'm not that savvy, I've tried the "re-size" thing and it wouldn't work for me.
Because you drive a Model K LOL! I post pictures that are up side down, in my files they are correct but downloading to the forum flips them sometimes. Also not very computer savvy.
I agree Rob. Pics I try to post end up so small you can't see the detail. I'd love to be educated.
I use a free software "image optimizer" from xat.com
It allows you to resize images pretty quickly and easily, and you can "compress" the images to a small file size without losing too much of the clarity.
For example, this image is only 70kb
I use Paint.net. You can make 'em as big as you want. Just resize them, then compress them to under 200K.
Do you think it will help with text? Often I'm posting old newspaper and journal ads and articles, and the already poor copy is often reduced to "mush".
You know how to butter a guy up
(Upsizing a "K")
You can drive a RHD Model T, with a ruxtell and a warford, downshifting going downhill following a school bus, but are afraid to use the right side of that mouse thingy. I make you guys do all the work by having to click on a link. I like the blurry pics that you have to scroll all over to see what it is. ws
Some software reduces more fuzzy than others. You have to find one that keeps your clarity....remembering that clarity will usually be a multiplier of the native size.
Not to go uber-geek, but a pixel line count of 96 will also show up quite clear on a computer. Many have their defaults set at 250 or 300. You just waste space and wind up with teeny weeny pix, 96 is fine for viewing...if you want to make a print, ask the poster for a full size PM.
The other misconception is that you have a 200kb limit. No you don't! There is always buried encryption that goes along for the ride and that counts in the limit! Most of the time I can get a 185kb to post, sometimes not. 175kb will always post for me. If you want to get real fancy, don't post as a JPG....post as a PNG. Somehow this always come out huge even for the same pixel count.
Yes Rob, I thought you'd appreciate the subject matter.
I used IrfanView, a free program. After lightening the image a bit, I used the "Save As..." and specified a file size of 185 KBytes. Normally, when I've used an image resizer program, the image is much smaller for the same 185 KBytes. I suspect the number of bits used for color information is different between the files.
Be sure to download the plugins, too, as one of them is needed to save the image smaller.
This is resized using only the standard iMac procedure.
This is with one of the free image optimizers. Changing resolution from 180 to 72 had no effect. I'll try one of the others later.
See if you can change the color depth to 256 colors (8-bits or one byte). That means each byte in the file will contain more picture pixels than normal "full" color at 24 bits (3 bytes), 8-bits each for cyan, magenta and yellow (or RGB depending on your color model).
Well I just tried that IrfanView thing, followed their instructions on re-sizing, and it didn't make it smaller. I'll try the other program further up in a post maybe tomorrow and see what happens. Maybe I can set them smaller on my camera, but I'm thinking I've already done that and can't go any smaller. Sometimes ya can't win
I have been using IrfanView for years now. It's a great editing program and worth a try.
Even without the plugins, reducing the file size is easy (but maybe not all that obvious) with Irfanview. Open Irfanview, then open the picture you want to work with. On the Image menu, pick Resize/Resample... It doesn't show you the size directly, but if you pick something like 640x480 pixels, it will be fine. After you click OK, save the picture under a different file name and you're good to go.
Just did that with this picture. It's now 80K, reduced from 1.8M, and it was taken with a cell phone, not a "real" camera.
Irfanview is very powerful. It can do things like take a whole bunch of pictures of different size and resize them all to the same max dimension, rename them, and put them in a different directory. It is also great for doing format conversions.
Photoshop resolution test
Tim, I'd set the camera to take the best pictures possible, then make a copy for resizing so you still have the good original. If you start out with a low quality file from the camera you can never make it any better.
The explanation Rob is to reduce the color quality or bit depth of the photo as well as cropping to overall photo down to some smaller size that still shows the main scene (or automobile). Some software can't alter quality - higher priced stuff does (you gets what you pays for). I only use Photoshop. Color photos came be up to 24 bit depth while grayscale pics are only 256 shades. While it's easy to post large format grayscale photos it takes a bit of work to get an equally large color photos without loosing important detail.
I used to post large format photos here regularly until some of the dinosaurs started whining about them being too large for their 1990's computer screens. I quit posting photos and am quite happy leaving them to view 4x3 photos.
I use Microsoft Office Picture manager to modify pictures.
It allows me to crop, resize, rotate, compress, change the contrast, hue and saturation, and remove red eye. The only thing I have to remember to do is save my changes - usually with a slightly different name so I can retain the original picture
Windows XP - Image Resizer from http://windows.microsoft.com/en-US/windows/xp-downloads#2TC=powertoys
Windows non-XP - I've tried the following in Windows 7 http://imageresizer.codeplex.com/ Have not tried V3 though.
I think max permitted is 200KB.
I guess there should be a forum FAQ for this.
