Post Processing: Minimizing the Image Size.
« on: August 22, 2011, 08:21:00 PM »
Friends,
I had seen that many beginners in this forum Posts Large size jpegs which take both time and bandwidth to open. So this is my image saving work flow. Hope it will help someone.

This is based on Photoshop.

1. after processing, save the full size if you wish.
2. Resize by pressing Ctrl+ Alt + I.
3. Add the Minimal of Border if you wish. other wise a white/black stroke will do the job from Edit menu.
4. Merge all layers by pressing Shift + Ctrl + E.
4. From file menu select save for web devices. or Press Alt + Shift + Ctrl + S.
    a) Select Jpeg.
    b) Quality to 60%
    c) Select only Optimized.
    d) Leave Pregressive, Embed Color Profile, unchecked.
    e) Select Convert to sRGB.
    f) Select any preview type you wish.
    g) Select Metadata you want to embed with file.
    h) You could resize from here also, resize if you haven't done yet.
    i) Click Save.



Approx Image size you get. all sizes in px


1. 600  x 400 = 29.7-35 Kb (Standard Web size, I guess Ayaz uses this size, earlier I too post these size.)
2. 750 x 500 = 40-50 Kb (For Portraits and landscapes best size to post online of 500 px height)
3. 900 x 600 = 51-70 kb ( Macros or your shots has some fine details, Large size landscapes could also be posted this size)
4. 1050 x 700 = 65-90 kb (Detailed Macros, Mind your image will not be seen full in browser window and user has to scroll it. so avoid using this size)
5. 1200 x 800 = 80 - 120 kb (If you want to show very fine details in macros, Mind your image will not be seen full in browser window and user has to scroll it. so avoid using this size)
6. 2700 x 1800 = around 280-300 kb.  ( Never Post such sizes online, your Images will be stolen)

For cropositions, Always keep the Height of Image in mind. for height more then 600px generally user has to scroll the browser widow and not able to view the image at one go.

Post Small, And save time and bandwidth.

Please feel free to correct me as this is totally my exp. and thinking.

@ Vimal - I second that!

@ Vijay - I can't take shots like this, but I can answer that question. Insects have compound eyes - so literally a cluster of a many, many, many eyes that their brain then processes as a single image. One can't see that normally, but at this magnification one is able to see the hundreds of 'eyes'.

Vimal you didn't give us the complete picture. You missed posting the "to be stolen" size.

For those who do not have Photoshop (or don't wanna get into it), some nice freeware alternatives are: Paint.net and Gimp. While Paint.net is very similar to PhotoShop in it's appearance and easy enough to use, Gimp can appear to be very daunting at the beginning.

When converting images for posting in forums/galleries, I use Google Picasa a lot. It can be configured to save to a predetermine filesize and features adjustable quality. Saving the images in reduced size is as easy as selecting the ones you want and clicking on the 'Export' button at the bottom.

I have no idea of Picasa I uploaded some images long time ago and lost them for ever.

Also a bump for encouraging the use of low resolution/size files.

Vimal Sir,

   I too have a Nikkor 50mm f1.8 lens.. but I could never capture something like this... I just want to know how close you went to the subject.. and is the image a cropped one? I was wondering how could an insect be so steady for such a long time??
Please enlighten me!!
-An amateur started with Nikon D3000 with 18-55, acquired a SIGMA 70-300 and then a Nikkor 50mm f1.8 lens and recently exchanged my companion D3000 with D7000
Right now I can say that I am a Sr.Amateur :-)
