Pramod

Thanks for the feedback Pramod. Guess, I have screwed something up on home computer. They all look ok to me. I'll re-edit and post these.

Try to include negative space in the direction where your subject/subjects are looking...that way the frame does not look cramped.

Time lapse shot from Fisherman's wharf over look the Alcatraz Island on a cold evening.

300 photos shot at 15 seconds interval.

TG,
The negative space was kept on the other side on purpose. Basically, I was trying to create a point of interest outside of the frame and not tell the complete story. Also, wanted to create a bit of tension by including the negative space on the other end :).

I'll watch the video at home, don't wanna get caught watching a video at work ;).

HW, nice works, I felt the sunrise pic bit dark to my taste.
TG, that golden water was lovely, I am too young to comment on other technicalities !

Since we have already reached Pondy by now, here comes my sunrise !

Thanks Shaju, I'll fix it and re-post them. I don't want to comment on the color of your shot as my work monitor is screwed up at the moment.

I find that it is always better to use "Save for Web" option in PS for getting an upload version of the image. It will have optimum file size and can offer you good quality pictures at quality levels hovering around 90. You can notice that the "Save As" option will produce an image with same quality and bigger file size. You can omit any camera data when you use 'Save for Web'. In addition, I can convert my AdobeRGB pictures into sRGB without any notable differences in color tones.

You have to flatten the image to 'save it as' jpeg, but you don't have to flatten the image if you are using 'save for Web' option.

@shaju: The yellow look too unnatural in your sunrise shot
@TG: Took that from a Jet? Why don't you pull up the curve a little bit in this image

Thanks for the tip, it was not a silhouette attempt because if I moved even 6 inches from my spot, the sun would have hit my lens and spoiled the whole pic, so I was left with no choice but click few of the same, not knowing what it would convey to the viewer !:) I will post the full view of the beach umbrella below, but its a different message and another angle.

Its almost close to what I actually saw, not much PP is done on it than bit of contrast increase. Anyway we missed the sunrise at Pondy as it was very cloudy. We saw the sun when it was already up. :thumbs up

Life is a Beach !!

Sorry if the PP has gone bad. I had to remove 2 men, 1 huge water bottle and a portion of the building from it. Sharp eyes can spot them.

1. Flatten the image has nothing to do with quality and size.

In a layer base system such as GIMP or Photoshop instead of applying modifications on source file you can create layer and use various options to apply masks , curves , blending etc. Advantage of using layer is that you can go back and forth between the layers and save a lot of time to undo-redo which you would have done if you were working on original layer.

Flatten just means that in final image only the final picture is saved and layer information and history is not preserved. Yes this may reduce size as well but objective is to remove the intermediate working data which is redundant.

2. To reduce the image size for uploading on web , there is a better option ,

Go to Image size tab and choose the size you want , click for lock aspect ratio, for example choose 1024 and software will pick other axis size automatically depending on aspect ratio

Now in the interpolation option choose "bicubic"

Bicubic interpolation preserves the image sharpness which is lost if you are saving it otherwise. This is more evident if you are preserving for very small size such as thumbnail.

I did not say that flattening has something to do with image quality. I am well aware of all the details which you wrote. I agree, and in fact, doing your editing using layers is not destructive compared to doing the editing in the image itself directly. Too many such operations can leave the image in a bad shape, for example, it can cause more posterization than same image whose editing is done in layers + flattening at the end.

I do Save for Web because I get to keep my picture with all layers so that I can still continue my editing in future. I save it as psd, while I have another smaller image to upload. I know very well about the image size operation you told, please check all my images posted here, all are in the range of 1000x800. The original image size is bigger as it is coming from a 10MP cam.

The point was that if you use Save for Web with very high quality, you can get an image which is smaller in size than an image which you "saved as" - both having the same image size.

Example: Open a high res image (orig.jpeg)
resize it to haev a width of 1000 and Save As another jpeg. (A.jpeg) Let the quality be 11 (out of 12).
Now, Use option 'Save for Web' on orig.jpeg, and save a web version with same image size as that of A.jpeg, say B.jpeg. Set quality to 92 (Out of 100)
In most cases, B.jpg will have less file size than A.jpg, but both will look same in terms of image quality.

Well, bicubic is the default one in 'Save for Web'. You can choose 'Bicubic Sharper' to have a sharper image, but I use bicubic only.

Extremely sorry for a moment I overlooked to whom I am responding.

stupid: The display image reminded you are the lens surgeon :-)

I am not sure If I understood the point properly will try this out and check size , Usually while using Save as I choose the Jpeg quality little lower then max and keep an eye on the image size , I think save for web puts a default value for jpeg quality.

bicubic does not appear by default in GIMP 2.6 for me also have not noticed bicubic sharper either so will search for it.

Thats where you get the advantage when you use Save for Web, the file sizes will be lesser for the same quality you select, so that you don't have to compromise too much on the quality to get your file size less than 1MB.

I remember making making my wife's 150x200 passport size photo jpg last day, for uploading in an online application. They want the image to be within 20KB in size.

I did all the editing and finally tried to 'Save As' and I was unable to get a decent image quality within 20K. I had to reduce the quality to 3 or 2 and even there the sizes were like 40KB. The image looked very bad with that low quality setting. (Camera data itself takes some size and it is useless in this case)

Then I used save for web, and voila! I got an image with 90 out of 100 quality setting and file size was 18KB. (90 /100 is like setting 11/12 in 'Save as')
