How to Resize Your Picture for Web




Before i know the resizing technique, i often complaint why i got bad picture after i resize it and post it for web usage. The picture seems dull and not sharp. While other people could still get best result even if they resize the picture.
I just find it out recently, and i hope it could be useful for you who have the same problem like i did before.


Resizing means compressing your picture, whether you compress the pixel quantity or consequently the dpi (dot per inch). Resizing also means minimize the data contained in your picture.
How a photo processing software manage to resize your picture? well if you use normal command as "image size" in PS, they simply cut the size of your picture without optimizing it. They don't care about quality or color shift after resizing process...that's my old days
If you don't do extreme resizing, this is OK...but if you wan't to resize your picture from 3500 x .... pixel into 900 x .... pixel and save it as JPEG, believe me..your picture would look like SHIT


If you want to get optimal result on your extreme resizing process, do the following action...resize your picture using into medium size using "image size" command...let's say 1024 x ..... pixel, with 200 dpi (i often use this setting)
Then after resized, look in the File menu of PS, and look for "Save for web & devices"



Find it?
OK, then change the image size as you need, and then look for the play button beside preset...
set your required file size...



and WHALAAA...save your picture and it finish
Very simple...but the result is very different indeed


Good luck guys

Photo Editing - Do you need to edit your picture?



When i begin taking picture back several years ago, I never wanted to edit my picture...
I only use RAW converter in Photoshop and what i convert is the final result.
Why? because i want my picture to be original from what the camera shoot.
Until i begin to realize that the RAW file from the camera (or NEF in Nikon) is simply: RAW...and that's why it is called RAW.
Different camera tend to produce different tone, even if it is from the same manufacturer (with different type ie: D700 and D200)
Even the pro camera usually create a RAW picture which is dull (less contrast), but they really preserve huge details --> what that huge file is for? the answer is to be post processed!.
The latest camera from Nikon already support Picture Control capability, which may produce many different color tone from single camera...and it is fully customizable. You can create dozens of picture control in your camera, which create various tone result...so if you still think that what you get in the camera is original, think again pals:)
Our friend in Canon also has it, but i don't remember what it called...you can turn your blue colored sky into twilight color, make the green leaves popping etc.

If you want to edit your picture...from RAW file, we need to convert it into semi RAW (which usually TIFF format) by using OEM's RAW converter before editing in Photoshop.
Can we use Photoshop to convert those picture??? Why should we bother OEM's RAW converter which is double handling?
Below is the comparison between Photoshop RAW converter and Nikon Capture NX as RAW converter:


PS direct convert


Capture NX convert

Those picture is taken as is, no editing, no cropping, only resize and save in JPEG from NEF
The difference is the 1st picture is converted directly in PS, resized and save as JPEG
While the 2nd is converted in Capture NX, saved in TIFF, converted into 8bit, resized and save as JPEG
Different??? for me yes

Nikon Capture NX is very powerful, not only converting the RAW file...but you can also edit the picture in NEF format, and save it as NEF file! You can dream about it in Photoshop:)
The editing is also very simple...the U-point technology allow you to edit the picture by zone.
No more layer required, no more selection, masking bla bla bla....
I always edit my picture in Capture NX, and use Photoshop only for noise reduction, sharpening and image resizing...very simple indeed.
The U-point smartly detect and edit only the similar color tone. Therefore you can edit pictrue background, without effecting the skin tone.

Then maybe another question...why I convert into TIFF instead of JPEG during processing in Photoshop?
If you convert from NEF into TIFF, you will find a huuuge file size. This is because TIFF is saving the picture in 16 bit format. Preserving more data (color, smooth gradation etc.) so we can save it without degrading it's quality.
When you satisfy with the result, convert it into 8 bit to be able to save it in JPEG format...
You will get optimum result
By the way...sharpening must be done on the very last step (after converting in JPEG)...why? because you will reduce the sharpness if you do conversion or resizing after sharpening.

After you read my opinion, maybe you'll ask: So if photo need to be edited, then what's the difference between photographer and photoshoper...???? Here's my personal opinion:
A photographer try to maximize the picture result from their camera (good detail, sharpness, depth of field control, correct exposure etc.) so when they need to fine tune their photo...it would be minor (saturation, contrast, sharpening etc) no need hundred of layers like photoshopers did. They enjoy taking picture, and not to sit in front of their computer a whole day only to edit one picture.
A photoshoper usually don't really care about the technique...bad exposure, reckless aperture setting, weird composition etc. but they try to make it good using photoshop.
They usually also add something which actually do not exist in their shot...ie. additional Ray of Light, Additional bird in the sky, fake fog above the lake and many more.
Well...that's my personal opinion

So...does picture editing is required? For me...Yes, but you should now the limit between Photographer and Photoshoper above:)

Jagir Bridge - Surabaya



I stay at home during this lebaran (idul fitri) holiday, simply because my daughter is still 1 month old, and it's quite impossible to bring her out for vacation.
I went to Jagir bridge which is only around 10 minutes from my house.
This bridge was very old and built by Dutch during World War II and used to control the water flow in Kalimas river.
Kalimas it self was a busy river which used for domestic harbor up to now.
The neighborhood around this bridge was not so safe these days, simply because this area was a crowded slump, many illegal house was built around here.
Actually if government willing to take care of this place, it would be a good city icon and it could be a nice tourism and photo object.
But since the area is not safe, people tend to stay away from this area


If you want to go here, you can see from the map below...or you can simply search "jagir" in google map:)

Bromo Plateau & Savanna

Nikon D200 f/161.1 sec iso 100 exp -0.7 20mm Tokina 12-24 f4
Last month i went for photo hunting to Bromo with my SPC friends (Sampoerna Photography Club). We depart from Surabaya at night (10.00 pm) to ensure we could get sunrise in Pananjakan.

Nikon D200 f/10176 sec iso 500 exp -0.7 38mm Nikkor 17-55 f2.8
From Surabaya, we're heading east to Pasuruan...then between Pasuruan and Probolinggo we turn right heading to Bromo - Tengger - Semeru National Park.
This road is common road and many people usually went to Bromo through this route.
After arriving in Ngadisari village, you could rent a jeep with fee around:
  • IDR 275.000 --> Pananjakan and Bromo Crater only
  • IDR 375.00 --> Pananjakan - Bromo Crater - Savanna
This is the common road, but actually there are some other route to go to Bromo:

Nongkojajar--> the route started from Lawang, a small city between Malang and Pandaan. The route is beautiful with canyon in left and right.

Pasuruan route2 --> before exiting Pasuruan town, turn right ...this will lead you to a totally different route. This route heading directly to Pananjakan, the famous sunrise viewing spot in Bromo

Tumpang route --> we could reach this route through Tumpang, you could either rent a jeep from Tumpang public market (in front of alfamart store). Or if you want more adventure, you can ride motorcycle (i've tried it without any problem), a car with high clearance also will do. This route is the most spectacular (at least for me), there are 3 waterfalls along the route, vast apple plantation, local farm and national park forest. The strange thing is that you could find a village in the middle of National Park...yes, this is Tengger tribe village. This tribe has settled in Bromo since Majapahit era.

Nikon D200 f/81/250 sec iso 200 exp -0.7 19mm Tokina 12-24 f4

Many have seen Bromo Caldera and crater...but few have seen it's beautiful savanna.

If you interested in seeing the savanna, it's located behind bromo crater.

Nikon D200 f/81/320 sec iso 200 12mm Tokina 12-24 f4

You'll be amazed by it's beautiful landscape...hills, canyon and blue sky create perfect photo object that will never end for you to explore.

Surabaya #2 - Kenjeran Photohunt

Nikon D200 f/5 1/750 sec iso 500 exp +0.3 matrix metering AF-D 80-200mm f2.8
Last week i have a long week end due to national holiday...
Bored being at home all the time and sick of shopping mall, i decide to go for photo hunting with my friend.

We decide to go to Kenjeran Beach...this place is located only ~20 minutes from center of Surabaya. From center of Surabaya, we can go east to ITS campus and look for road sign written: "Pantai Ria Kenjeran", yes and it's quite easy to find.

Actually there's not so much to see in this beach, the sand is muddy and black, the ship dock is deserted, only few boat is anchored in the dock.

But the sunrise from this beach is promising
