Photoshop magic..

During the function for my dad on mom  last week, I had to be performing a lot of things.. which meant my stint with the camera was done.. 

I usually don't trust others with pictures for events.. and definitely don't trust others with my camera.. however on recent trips, have been handing my camera to my baby cousin (who is not a baby anymore) and teaching her how to hold steady, focus and shoot with the 5D mark ii and she has a really good eye for composition.. told her to keep clicking and leave the rest to me to photoshop..

She did me proud.. We did hire professionals for the event but they are working on the photos. We should have great pictures in a week or two.

Saw this one pic where San has her cute dimply smile and I really wanted to make a portrait out of it.. (Credit to my cousin for cracking the right joke at the right time!).. 

The background.. I needed some recently shot greenery.. and the photo from Amethyst gave me an idea..

So here is 2+2=6..

The original..

the background from a group photo..

and the end result..

Have been lost in photoshop for a long time.. work calls tomorrow. My cold is almost bearable.. have been doing yoga everyday during the break and resting and working on photoshop as a good distraction.

Also my wife is back from India and that alone is a big relief.. my girls know how to press my buttons and get anything they want and sometimes I don't know if I am authorized to authorize things.. good that the big boss is back in the approval loop.

Ta ta for now..

Software tricks that compensate for hardware

If you hear about software compensating for hardware be it in imaging, networking, security, etc. etc. take it very seriously. 

Got to witness it firsthand over the weekend. We were at a friends place and one of our friends who works at Apple, whips out an iPhone8 and says "let me show you the portrait mode on this one". She takes a photo of me and with a single swipe on the icons in the bottom she was able to adjust the lighting on the portrait, AFTER the photo was taken. The background was also blacked out instantly and precisely.

It is interesting to note that Apps have figured out how to identify your face and put bunny ears on them, glasses and hats on your image and move them dynamically as you move your face. That is already 2016! as pointed out by my other friends. So the face and body recognition has come a long way. The speed and precision with which it is being done is what is amazing and scary! 

It takes me (and I do this with practiced ease) 3-4 minutes to cut an outline and create portait shots by blacking or whiting out the background. I use the smart cut tool in Adobe Photoshop CS5 and do a layer by cut followed by a solid layer and reordering the layers. 

The key issue is that the smart cut is only as precise as I can do it manually. My rush and crude job in the picture below shows that I did not get the boundaries right on my head line or right ear, which is because the background color blends with skin color or fuzzy boundaries are hard to delineate. The option is to gradually increase opacity between the layers. It can be done and it will take another few mintutes and can be automated.

How do you adjust the lighting post picture?! Think the iPhone8 is taking a page out of the Lytro book and doing multiple exposure shots (kind of like HDR but by adjusting focus) or is adding image sensor tricks to deliberately over expose or underexpose a group of pixels after it identifies the face prior to taking the pictures and is then able to play with this in the post processing. Dont know what kind of AI went into this, but whatever it is, very impressive!

Note that when I do smart cut and add a black layer, there is no lighting effect. I can also recreate part of the effect by creating a custom Vignette option. But I cannot change the local lighting on my face. It will always match the original. 

The "smart cut" being done with software is what is incredible. This is going to put portrait studio kits out of business. 

The SLR camera and lenses are temporarily safe. It still takes a good zoom to capture pictures of moving subjects against a plain backdrop and CS5 to adjust it. Maybe when you import the photos into an iPhone8 those photographs will be edited with a button click. Photoshop options and customized macros are going to be folded into the iPhone. You dont need those anymore soon..

One idea that I had was this.. Build a housing for an iPhone where the phone's camera focuses on an internal white board inside the box which replaces the plane of the full frame sensor in an SLR. You directly put your 2000$ lens on to this small box and the phone connects to an EF lens, telescope, binocular etc. etc. 

In the mean time photography enthusiasts like me will still lug around a heavy bag... 

Technology is moving very fast. Faster than a common person with respect to that technology field is improving. I am in hardware and see a scary progress in software. A software person is probably seeing the same thing in hardware space. The collective improvement is something neither one can anticipate or expect. . . it beats the average expectation by a wide margin!  The happy go lucky average users (all of us) don't see the larger picture of where this is going!

Why bother?

Sometimes San asks me why I bother to sit with Photoshop on some pictures..

See the original of this photo here..

Do you see that "Kebab me haddi" in the background? Well, he happened to be a nice guy, but as far as this picture was concerned he was an unwanted artifact. It was freezing out there, what with the glacier on one side and high speed winds on the other side. My subjects were literally 4 feet away and my zoom was at 17mm  to get them and the scenery in the frame. Simply could not get an angle where I could cut out the nice gentleman but my wife and daughter were flashing smiles at me and it would be criminal negligence if I did not click away!

Photoshop comes to the rescue. See the final picture!

Using the texture of the mountain and floating ice on another part of the picture, cleaned him out of the frame. On the one hand, yes! it is photo manipulation but on the one hand, I have something worth putting in our album!

Thank you Adobe for giving me the wisdom to know that we can always change things in "post-production"!

Memories..

BIL sent me an old picture while cleaning up his stuff from 2008.. 

It was a keeper! While the background distracts you, the smile on our faces is priceless!

Spent a few minutes in CS5 to get this one.. 

Wish to bundle her up like that now! 

See what I mean by they are growing up sooo fast?!

Thanks to my BIL for saving old pictures. Have purchased a negative scanner as my Christmas gift, thanks to Costcos 24 deals of Christmas in 24 days.. Have literally 1000's of negatives from 1989 to 2002 in India and in my closet. Can scan a lot of those before the film starts to decay! That should be a fun Christmas project to try and set up.

Day by day breakdown

The only way in my head to describe the Death valley National Park trip in pictures is to go day by day. Have finally finished processing all pictures from Day 1, uploaded the people pictures to Facebook to make the Mrs. and kids happy (they sit together at bedtime and surf facebook and this seems) and now uploading the nature stuff here. 

It does not make sense to visit death valley for a day or two. When Balaji told me we needed to take an extra day off for this plan, was initially not for it. We have never done a national park trip for more than 3 days. Then we did the internet learning and figured that 4 days in the park might just about cut it. 

It did not! We still missed a few spots after spending four full days in the park. That means the the next time we go, it has to be either :

- Rent and RV and stay inside the park or

- Stay at the one or two lodges inside the park and book it months in advance so we get a spot

We drove to a place called Ridgecrest after an 8 hour journey and rested that night. The next day (Day 1) we started at 8AM thinking that we will have time till 6PM to see things. The sun set at 4:15! We did course correct for this the rest of the trip. 

We went first to the Panamint area. There is a small store/ Visitor center with very helpful people and a very clean restroom there. You can also pickup things like moisturizers, sunscreen lotions etc.. there if you run out. 

There are beautiful views as you drive to this area

When you have a ND filter and you can do HDR.. you can almost.. almost make it look like what your eye sees.. but still it is only "almost". The human eye is the most amazing wide angle HD HDR ready thing and we usually do not realize it!

You keep walking through parched ground for a long time and 

then suddenly Darwin Falls!!!

We went on a dirt road for about a 2 1/2 miles and then went on a hike that definitely was more than a mile to see Darwin Falls ! There was lots of water flowing, considering we were in the middle of the desert and it was nice because we walked on the shade of the rock face. You are better off driving there in a Jeep or SUV instead of a minivan as your vehicle has to go real slow if it has low clearance! We did 10-15 miles / hour speeds throughout on dirt roads. 

It was really worth the effort as we got great photo ops on the way and at Darwin falls. Then we came back to the Store and had lunch.

Here is one with my two little bear cubs in a little cave! 

For comparision see bearcubs from Yellowstone many years ago..

It was already close to 1PM when we started lunch and we left the Panamint area by 2PM to go to Stovepipe Wells area.

That is almost an hours drive and we registered there at the Ranger station. That is when we were told "Sunset in an hour!". So off we went to Mosaic canyon which was the closest thing to see from the Ranger station. 

It was another 1/2 mile hike inside a canyon with smooth polished walls of marble and rocks of many colors and given that the sun was going down, it was like being in the Mckennas Gold movie! 

We have seen many canyons, but nothing like this! The kids could slide off some marble slopes.  We came out of Mosaic canyon and the sun had gone down but it was still bright out.

Started driving out of the park at 4:30 and it took us a good 2 hours plus to get back to Ridgecrest and got some fantastic views..The next day we started early amid protests from the kids! "This is a vacation, why do we have to wake up at 6 every day ?! Not fair" etc. etc. 

Wake up at 6 we did.. will share pictures from Day 2 in a few days.
