Done it (I think)

Just done my first upload of images, cant get over how small they have to be, ie reduced from 47 /52 Mb down to 300kb. They look a bit soft on my screen, is this normal? If not how do I get them sharper at this size, please.
Charles.

Re: Done it (I think)

I used photoshop

1) I resize the longest size to 1000 pixels and turn the dpi to 72 pixels per inch.

2) Then I used the export for Web option and save the file making sure it is under 300k.

(If they look soft then maybe an Unsharp Mask on the exported file)

Re: Done it (I think)

how are you resizing your images? the most simple way is to find a tool that will resize them in a batch (i.e. point it at a folder and it outputs the resized ones in a new folder) this is the simple way,. some great free tools,. I generally use IrfanView - Official Homepage - one of the most popular viewers worldwide - v easy and great results,. you can choose the amount of jpeg compression and also how much sharpening is applied during the resize operation

if you want to get into the black art of usm then check out the 6 part sharpening tutorial at Ron Bigelow Photography Articles (about 1/2 way down on the right hand side underneath heading 'Editing/Photoshop')

Re: Done it (I think)

Welcome to the forums blackadder,,,. Most of us but not all use photoshop.....I just heard that little drop in the water noise when a rock drops on a smooth surface of water,, wait what was,,oh yea. I make an action for portraits and another for landscapes. If you know what it is, thats ok. It's a recording palette that records your actions, after you hit the stop button, it will repeat what you did everytime the same way. I made mine 700 pixels on the long side because thats what I use on the web for every thing. Chris does his the same way with way less babbleing going on..

Re: Done it (I think)

Thanks guys, I use lightroom, but got elements 10 for "cleaning" images, ie remove power lines etc from landscapes. I used elements to resize, and converted to save for web. The full size images are pin sharp at normal size (4368 X 2912) so I put it down to the huge amount of info dumped to get it so small. I will give usm a try on the small image to see what happens when I view "fill screen" size (27" hd screen calibrated)
Thanks Charles.

Yes, your images do seem do look of poor quality to others, and very highly saturated.

In comparison to others.

Charles.
I think that the way you sharpen and downsize the images must be the cause as others have said. Sharpening is an art in itself, and everyone will have their own favoured methods - none of which is right or wrong.

My routine is that using Photoshop from editing a 16bit tiff file (around 70mb), I apply sharpening and convert to 8bit tiff for storage. I then reduce the dpi to 72 and the longest side then ends up at 1021 pixels. I sometimes reduce this too, but not below 800 pixels. For portrait orientation I'll reduce the height to 900 pixels.

Some say that you should re-sharpen when you change the image size but I don't usually do this. I never use the save for web as this usually brings up a dialogue box telling me that the image exceeds the file size that save for web is designed for. I 'save as' a jpg and use the quality slider to bring the file size below 300kb. Most images will save at about 8 to 10 on this slider, but occasionally I've had to go to 4 or 5, but not very often.

I have occasionally exported jpgs from Lightroom and have had no problems, but I mostly go through PS to finish off before saving. There are a couple of good sharpening pre-sets in LR, but I've added a few of my own too. RAW files usually benefit from input and output sharpening - that is in LR and PS. Frequently the only tweaks I make on an image is to sharpen in LR than again in PS.

You need to play around with this until you can get satisfactory results then you'll have no further issues.

Re: Done it (I think)

Yes that looks fine Neon.

I suspect your right Charles, getting the resize right will improve the web look. I use an action like Boofers too. Have not got lightroom, but there must be a way using that too, as many here use it too.

Re: Done it (I think)

I know it's off topic (a little) but setting/changing the dpi value has no effect on how an image is viewed on a computer screen, dpi is a scaling factor used for variable pitch output (e.g. printers) Say No to 72 dpi

it's because photoshop is confusing,. dpi is a scaling factor that is ignored by web browsers / monitors,.

so you have for example a 4000x4000 pixel image,. we need it to be let's say 1000x1000 pixels - just change the pixel dimensions and you are done (we can put the dpi at any figure we so choose because it's ignored)

where the confusion in photoshop appears is that people are looking at the wrong thing,. so going back to our 4000x4000 pixel image,. let's say the camera arbitrarily sets the dpi to 300 (it could set any number - but most happen to use 300dpi) - if we printed that out (dpi!) and our printer took notice of dpi (many consumer printers and photo kiosks willfully ignore dpi) that's an image about 13 inches square

what happens when you change the dpi value on photoshop it assumes you want to keep the print size the same 13 inches (!) and then it moves the pixel number downwards to achieve this,. so setting 72dpi at 13 inches is 936 pixels

as you might tell it 'kind of' works but is totally backwards way to view what's going on and 72dpi is just confusing

Re: Done it (I think)

That might be so, but I've just resized the same tiff file and converted to a jpg, and the 300dpi one at 706x900 pixels is just over 400kb where the 72dpi one at 706x900 is 211kb. Neither was measured in Photoshop

oh,. that is something different (I thought you meant resizing an image by changing the dpi),. your case above could be a fault in the software,. the files should be the same (honest!) the dpi is encoded into a couple of bytes,. actually found a link which explains better Image DPI on the Web

No - the thrust was about reducing file size, and both resizing and reducing the dpi will do this. The combination of both processes results in the file size of the re-sized image coming right down. In my example the bulk of the reduction has been achieved by re-sizing, but the final reduction of close on 50% is due to the dpi.

Everyone will have their own routines that work for them, I was just saying what I do as an example - not that it was the best/only way.

the '72dpi' issue is quite engrained,. some of my friends are graphics/web professionals and were taught to use 72dpi online,. it's very confusing,. the above link describes why changing dpi doesn't change filesize,. it's a scaling factor only

Nevertheless, it is good practice to use low resolution images on line for security reasons.

Re: Done it (I think)

If you are using Lightroom, then one of the easiest ways to produce a version of your images for web or similar use is to use "Export". It is similar to the "Image Processor" facility in PS but even better. This will allow you to resize, save as JPEG, change to sRGB, sharpen for web, add a watermark and other processes if you wish. It is logically laid out and very easy to use. I use LR Export for all my competition projected images and any web output. You can export single or multiple images.
