The normal size around here is obviously 1024x768. Ideally, this looks great, but the accptance rate is more "competitive" so to speak. If you can manage to get something in bigger with relatively good quality, then the accptance rate gets a little better.

Just depends on what you fancy.

I myself go for the 1024x768 as I see it standard...but that doesn't mean you have to.  Smile

From the upload -FAQ, hope this would help  Smile

How important is scanning and photo quality?
Very important! We only accept the best and a very high percentage of the photos that are uploaded are rejected due to low scan or photo quality. A few pointers: Use a good camera and scanner. Spend time finding the best DPI and other scanner settings to get the final image to look as good as possible. Also get a photo manipulating tool like Paint Shop Pro or Photoshop (or some similar software that came with your scanner) and use the "Sharpen" feature when needed. The most frequent reason a photo is rejected is due to a blurry look. Furthermore the photos need to be bigger than about 1024x768 pixels. We suggest using sizes around 1000 pixels in width. Anything bigger than 1600x1600 will automatically be resized. For portrait format photos we recommend the longer side to be 1024 pixels at least.

1024x768 is not standard aspect ratio for most DSLRs CCD/CMOS chips. Its wider. So learn basic photoshop skills, set the cropping tool to 1024 width and you should end up with something like 680 height. I personally always keep my pics in the same aspect ratio.

So basically you have 1024x768-1600x1600 space to work. What is acceptable? I have yet to get 1024x768 to work without distorting the photo. Mine will come out to something like 1024x637. Even with cropping I only got 680 like ChrisH stated. Arggg this will bug me but I guess you have to toy with it to make it work. One quick question.

Does size really matter? (So to say  Big grin ) When uploading, where should I shoot for bigger or smaller?

Thanks again for all your help!

Smaller images will show less artifacts (grain, compression etc.).

If you use photoshop, open your image, press C to activate cropping tool. Now drag across the entire image and let go (press F once first to get the image centered if you like). The whole image will be selected and there will be 8 small boxes, one in each corner and one in every middle. Now click and hold a corner box, hold down your shift key and drag. The bounding box will now keep the aspect ratio of the original image, and you can crop as you wish without losing the proper ratio. Once satisfied, press enter to crop. Now do your editing and downsize the pic to 1024x for instance. In image size dialog, make sure "Constrain proportions" is checked.

Just a quick question about my cropping tool: When I go to crop in photoshop, the little boxes you talk about do not show up, and the cropped area is seemed to being held in a certain aspect ratio. Do you know how I can fix this. Thanks.

Newark: Are you using the crop tool, or are you using crop from the dropdown menu? In the toolbox is where you have to select the cropping tool (or press C), then you have to click and drag to select the part that will become the final image.Everything outside will be grey. When youve done that you will see the little boxes.

Dont use "crop" from the dropdown menu. Also, depending on PS version, I have CS, you'll see some info on the tool just under the dropdown menus, if theres a certain size/dpi entered there in the boxes you have to clear them to be able to crop freely.

hope Im making sense here =)

My photos usually come out around 1024x(685-720)....depends how much you crop from the top and bottom. 1024x across would be ideal though.

Thanks guys..I wil have a go, I am presently baffled with the rejections I keep getting, I have had many images published in various magazines and some newspapers which have been rejected here at A.net..

I have two rules of thumbs:

1. Ratio
2. Size

----

Ratio:

Is it film, digital or digital SLR?
Film and digital SLR tend to use a 3:2 ratio.
i.e. 3 units wide, 2 units high.
Normal Digital tend to used monitor oriented resolutions instead of photo oriented resolutions. so the ratio would be 640:480 = 1024:768 = 4:3
I recommend keeping the ratio of the original shot unless the shot warrants it

This is my only shot which didn't stick to the standard ratio. I would normally recommend against this.... but in this example, I hope you understand why.

Size:

As a screener I must first warn against using shots 1600 wide.
While it's a great size for detail, it automatically reveals flaws that might otherwise go unnoticed in a lower resolution.
Unless your camera equipment and editing workflow are flawless, then expect a lot of rejections.

In my experience with rejections, I would say that more than 50% of the 1600 wide shots get rejected

The size of your shot should be calculated on the ratio (above) and the longest side. Upload FAQ instructs that the longest side must be greater than 1000 BUT less than1600.

Somewhere towards the lower end of the scale is recommended.
I recommend:

For film scans: 1000 to 1024 pixels wide
For non DSLR digitals: 1000 to 1024 pixels wide
For < 4MP DSLR's: 1000 to 1024 pixels wide
For modern DSLR's: 1000 to 1200 pixels wide

Above this, you can take your own risks with rejections.

Take this width, and find the height:

E.g.

Film/DSLR ratio - 3:2

Width of 1000:
Side = (1000/3)*2= 667 (rounded)

Width of 1200:
Side = (1200/3)*2= 800

Digital ratio - 4:3

Width of 1000:
Side = (1000/4)*3= 750

Width of 1024:
Side = (1024/3)*3= 768


Hope this clears up your question.

Quick PS tip, when cropping you will notice at the top width and height boxes. Put '4 in' in the width and '3 in' in the height box and leave the resolution box blank, then when you drag your crop across the picture it will retain its 4:3 ratio. All you need to do then is resize the width and the height will follow in the correct ratio Big grin

Better still Jid....

If you put 1200 px and 800 px in the crop boxes, it simply crops to that exact size and maintains your aspect ratio.

This way you get to frame, crop, resize in one step.

Hi guys,

I have set my Canon 300D on Medium Sharp image size which equates to about 2048 pixels wide. I make sure the object I am photographing is about 2/3rds the view finder size. During post editing I simply set the crop size to 1600x1200 or 1365x1024 or 1024x768 in order to maximise the object size. Is this the right way to go?

Related to this, I submit images that will always have the 1024x768 ratio so that they fit on the PC screen. I have found before that often pictures submitted by other photographers are at 1024x678 so they never quite fit the screen totally. Why?

Thanks, Marc

I don't think setting your image quality to Medium Fine is a good idea, unless you have a low capacity CF card (in which case I would get a larger CF card). Your camera is capable of recording 3072x2048 pixels so why not record all of this information. Use Large Fine or Raw. This ensures you are recording the highest quality image possible. You can then downsize (resample) it to the desired size during post-processing.

Regarding your second question, not everyone uses a screen resolution of 1024x768 pixels. Other choices include 1152x864 and 1280x960 pixels. Trying to size your image so that it fits peoples screens is therefore a futile exercise, unless everyone agrees to use the same screen resolution but I don't see that happening. Some (or many?) people simply maintain the aspect ratio of the original image, which is generally 3:2.

CB,

Thanks for the reply.

OK, but if you resample an image (from 3072 to 1600 for eg) it becomes "fuzzy" as the pixels are also resampled. Do you then use "adaptive unsharpen" etc to make the picture clear again? If so, does this not make a poorer quality image than if it had been captured at a lower size without any resampling?

My reasoning, as per previous posting, is that rather take the picture at a size that will require the least amount of resampling so that you do not loose any "information" in the pixels. Then, just use a mask (say 1600x1200) and resize the image that way without any resampling.

Bell, youve got it all a little backwards. It is _always_ better to start out with the highest resolution / lowest compression possible. Personally I downsize incrementally, it increases quality even more. For instance going from 3000px, 2500px, 2000px, 1500px, final 1100px. I'll sharpen both original size and then sharpen the final size with various settings.

Also, I don't shoot for a.net and computers solely, and I dont like the 4:3 aspect ratio of a computer monitor. I want to keep the picture the way I saw it in the viewfinder. Maintain aspectratio of your original shot and simply crop slightly to center a/c is the way to go imo.

With each resize, crop, resample.... you will LOSE quality.
Keep it simple!

I perform level/contrast/colour/shadow-highlight alteration prior to rotation, at full res. I then rotate!
After rotation I crop/resize (one step in Photoshop) and perform FocalBlade or USM sharpening last.

You dont lose quality in every downsize, try it and you will see for yourself =)

I am still struggling with my image processing but am getting better (I hope) so I desperately need some feedback please ! My acceptance rate is still not very good, but improving. My biggest problem seems to be that I am not very good at recognising the onset of jaggies.
Adobe say that the last processing should be the USM and that this should only be done once as the effects are different if you repeat it at different levels. A screener recently gave me a hand, probably pissed off with me, (thank you Peter) and he suggested re-sizing to 1024, then USM 200, 0.3, 0 then 200, 0.2, 0 once or twice. That works for a.net !
What has surprised me is that for USM virtually everyone uses a threshold of 0. If that was the best setting, why have Adobe included it in all of their programmes? (Americans, please note the correct speelling)
With the threshold set at 0 everything becomes a candidate for sharpening, including grain/noise and this is contrary to Adobes recommendation.
For Digital, my 10D I now set it at 2 and for scanned slides at 7. they then stand USM 200, 0.5 or 0.6, 7 without the grain being obtrusive as it was with the threshold at 0
I did use Neat Image but have stopped doing so and have started using Smart Blur, a mere hint to soften some of my old, grainy shots, levels 3,4, 7 and I find that they will stand a touch more USM afterwards. Probably completely wrong but it does seem to work.

It is true that when you downsize you lose quality, but this is no worse than not recording the information at all. In fact, IMHO, not recording the information at all is far worse. You've paid for a 6.3 MB camera but with the Medium Fine setting you're using it as though it were a 2.8 MB camera! If you want to print your images the extra pixels are very useful.

Mick, if you're going to give the Americans a spelling lesson, probably best to spell the word 'spelling' correctly.  Smile

Thanks to everyone for the input on this discussion - much appreciated.

CB,

Will give it a bash at the higher end of the image size and see how things progress from there.
