Large Image Files – PSB vs TIFF

In this post, I am going to explore some basic differences between the various Photoshop file formats: PSD, TIFF and PSB

I’m working on a very large image, and it is a panorama of (42) 10 MP captures, each between 8-10 MBs, merged into Photoshop CS5.1.

Photoshop CS 5.1 can not save anything over 2.0 GBs as a PSD file…

The TIFF file is 3.7 GBs…

and the PSB file is 2.7 GBs…

Open Questions

In this example above, there is approximately 1 GB (25%) loss in file size…

Where did it go?

  • File compress?
  • Color Data?
  • File Optimization?

Findings

  • Photoshop PSD (max) file size: 2 GBs
  • Photoshop PSB (max) file size: 4 exabytes (300,000 x 300,000 pixels – 350 x 350 feet)
  • TIFF (max) file size: 4 GBs

Observations

  • Lightroom is not “seeing” my 2.7 GB PSB file, but is “seeing” the 3.7 GB TIFF.

anyone got any ideas?

Post Hurricane Irene Nature Walks

About an hour ago, we finally got our power back!

We lost it Saturday night around 10:32pm during “Dr. Who”… I mean Hurricane Irene.

I was monitoring my various networks, watching for things related to the storm that was all around us.

The TV was nothing but an Emergency Broadcast transmissions for tornado warnings all over the area.

The first alert was described as strong storm, with possible circular rotation for areas to the south, starting in New Castle and heading towards Kennett Square.

About 5 minutes later, there was another warning that included the King of Prussia area.

We are right in the middle, and needless to say, I was a little nervous.

At 10:31pm, I posted to Facebook that our lights were browning…

Then the Power was gone…

I turned on the radio and listened as I paced the house, moving from the front to the back, and occasionally into the garage to look out into the night from one of the opened doors.

Sometime around 3:30am, I finally laid down and continued to listen to the radio before I falling asleep.

I was woken up by my wife, as she prepared snacks for the kids, who were upstairs watching a movie on the iPad.

They were happy.

Walking around the house, I surveyed out all the windows to see what the outside looked like, and how many branches would I be picking up later.

I also watched for cars to gauge how the roads were, and as I saw more, I wanted to go out to see for myself, and so did Madison.

We got down to Kerr Park around 11:30, and saw several other people already exploring what Irene had left.

After parking, both Madison and I walked across the water-logged grass, and headed toward the Brandywine creek, which was well over it’s banks.

The small little stream and bridge in the middle of the park were covered with several inches of water.

One could also see that one of the older trees and fallen over during the heavy winds from the night before.

After walking around some more, we headed back to the car, and off to the Dam along Struble Trail.

When we got to the small little parking area, there was another family already investigating the dam and all the water that was flowing over it.

We finished taking our pictures, walked back to the car, and on to home.

Once there, Logan was now ready to see the outside world also, so we jumped into the car, and headed to the Dowlin Forge Road entrance to the Struble Trail.

I was actually a little surprised to see as many folks walking the trail, but considering that the power was still out, what better way to spend a Sunday afternoon!

As Logan and headed West, we found our little trail that leads down to the edge of the Brandywine, but were confronted with a large puddle from earlier flooding. Logan jumped on my back for a piggy-back ride across and we continued on.

It was loud and many of the ‘normal’ creek-bed features, were covered in several inches of deep water.

I wanted to find the “Creek Claw“, but with all the water, I knew that it was not going to be, but I was able to find the “Hobbit House” tree.

As I took several different angles, I reminded Logan that when the water was lower, he was able to stand inside.

He looked at me with disbelief, and then went back to lightsabering the tree branches.

We continued down the dirt trail, and back up to the main paved trail.

On the way back to the car, we only saw one tree laying across the trail, which was a surprise.

From the parking lot, we drove along Creek Road (Rt. 282) back into Downingtown, and on to Kerr Park for a quick stop, and no camera.

As we walked around, I pointed out where the water had been earlier and told him I would show him the pictures later, once we had power again.

The WORST part of a Facebook Post…

Knowing that EVERYONE is going to read it…

– Then waiting for the grammatical Critiques…
> Not ‘said’, but thought…

– Then Factual Critiques…

– Then Reunions…

– Then Face-to-face…

Damn it! I’m old enough, I do not CARE!

It was the computer’s FAULT for not knowing what I was thinking!

Silicon sux!
